Solar energy is being adopted by more and more households and commercial institutions since it is a cleaner, greener, and affordable alternative to traditional fossil fuel-based energy sources. A solar photovoltaic system captures solar energy and converts it into electricity. Transitioning to a solar photovoltaic system can offer the consumer immense cost benefits in the long run. In this article, we will look at all the major components which are a part of any solar photovoltaic system, and uncover the anatomy of a solar PV system

The following are the most essential components of any solar PV system:

1. Solar PV Panels


Solar panels are the most expensive components of any solar PV system. As a matter of fact, they will make up 60 percent of the cost of the system. It is, therefore, essential that while choosing solar panels, go for the best ones available in the market. Solar panels simply absorb sunlight and convert it into electrical energy. However, at this stage, this electricity is not useful to us - it is a low voltage, DC electricity, and cannot power any appliance in the home or office. It is at this stage that the inverter becomes another essential component of the solar PV system. 

2. Solar Array Mounting Racks

There are three ways in which solar panels are mounted: on roofs, on poles, or directly on the ground. Before they are mounted, they are joined in arrays. 

The most common form of mounting is roof-mounted solar panels. It is also the most aesthetic and efficient approach. However, roof-mounted systems require high maintenance. For instance, clearing snow or repairing the panels in a high-rise building can be an issue. 

Pole-mounted arrays, on the other hand, can be set up at a fixed height which is easier for their maintenance. However, a major drawback of this form of mounting is the additional space that is required for the arrays. 

Ground systems are simple to install and cost the least. However, it requires an enormous amount of space to install solar panels on the ground and they cannot be used in areas where there is a regular accumulation of snow. 

Irrespective of how and where you mount the arrays, there are two types of mounts - fixed and tracking. Fixed mounts have their angle and height set and they do not move. Tracking arrays on the other hand move east to west to adjust their angle for maximum sunlight reception. 

3. Array DC Disconnect/Isolator 

Another important component of a solar PV system is the array DC disconnect. It is used for disconnecting the solar arrays from the mains for the purpose of maintenance. It is called a DC disconnect because the solar panel generates only DC current before the inverter converts it into AC. 

The DC isolator is a manually operated switch. It aids in the quick shutdown of electricity transmission from the panels to the inverter in emergency situations. 

4. AC Isolator 

AC isolators work on the same principle as the DC isolator, but in this case, the system can be shut down by disconnecting it from your home. This is done during emergencies. However, remember that there is a specific shutdown procedure that needs to be followed while disconnecting. Follow the instructions carefully, and hire a qualified solar installer to conduct any kind of maintenance work. 

5. Inverter

Luminous Solar Inverter NXG1400 12V Solar Home UPS

This is the second most expensive component of a solar PV module after solar panels. Since standard home appliances run on AC current, the low, DC current generated by the solar panels cannot be used. It is the inverter that converts the DC current generated by the solar panels and the batteries to the AC current used by the appliances. The inverter boosts the current-voltage to 240V AC, which is suitable for all home appliances. 

6. Battery Pack

Luminous Solar 150Ah Battery

A solar PV system entirely depends on sunlight for generating electricity. However, sunlight is available only during the daytime. Besides, during rainy/cloudy days, the duration of sunlight reception diminishes. Therefore, a solar PV system comes with batteries, which can store the energy produced during the daytime and can be used to power appliances throughout the day. 

7. Consumption meter

The consumption meter is an optional device, which enables you to monitor the energy consumed by the household and the energy generated by the solar PV system. It also helps you determine the amount of money you are saving on your energy bills due to the use of solar energy in real-time. Besides, it helps you know when you can shift the use of certain appliances to particular times during the day, when energy generation is maximum. 

8. Power meter 

Solar energy, in most instances, is not always sufficient to power all the appliances in your household throughout the year. There are seasons when the sunlight reception is not enough to generate electricity to power the house. Therefore, there must be an alternative connection in place to the main electricity grid of your locality. A power meter measures the amount of power used from the grid. In solar PV systems which use net metering, the power meter is bidirectional, i.e. it measures the amount of power the solar system sends back to the grid. 

9. Backup Generator

Solar PV systems which are not tied to the power grid make use of a backup generator to power the house during periods of low power output. If you are concerned about the environmental impact of generators, you can install a generator that runs on alternative, cleaner fuels such as biodiesel, rather than diesel or kerosene. 

10. Breaker Panel and Circuit Breaker Panel

The breaker panel is the point to which the power source is joined to the electrical circuits of your house. A circuit consists of a continuous route of wire that connects outlets and lights in an electrical system. There exists a circuit breaker for each circuit, which prevents the appliances on a circuit against overloading and causing a fire hazard. In the event of an overload, the circuit breaker will switch off, thus, interrupting the flow of electricity. 

11. Charge Controller 

The charge controller maintains the proper charging voltage for the batteries of a solar PV system. Continuous voltage can lead to an overcharging of the batteries. By regulating voltage, the charge controller prevents overcharging and allows charging only when required. 

12. The main fuse box (switchboard)

In general, if you are not using an old or a tiny fuse box, you can make use of your existing fuse box for the newly installed solar PV system. However, your new system will be wired into your existing fuse box, so that it can supply electricity to the house wiring, grid, and meter. 


Thus, in this article, we listed down all the essential components of a solar PV system, uncovering the anatomy of a solar PV system. Solar energy is a clean and green alternative to conventional fossil fuel-based energy solutions. It is a futuristic energy solution and must be adopted on a larger scale to mitigate the effects of climate change. 

With solar energy being adopted by various stakeholders as an alternative to pollutive, conventional sources of energy, solar PV modules are becoming increasingly popular. Solar panels are the most essential component of any solar PV system. In this article, we will chart out the steps in the process of manufacturing a solar panel. It will provide the readers with a basic knowledge of how solar panels are made

Step 1: Sand

Quartz sand

Sand is the raw material used for making any solar panel. Most solar panels in use are made of silicon, which is derived from soil. It is an abundantly available material, and in fact, the second most available element on our planet. However, the conversion of sand into high-grade silicon involves a high cost and is an energy-intensive process. Silicon with a high purity level is produced from quartz sand, by heating the latter in an arc furnace at extreme temperatures. 

Step 2: Ingots

The silicon is collected in the form of solid rocks. A large number of these rocks are melted together at very high temperatures to extract ingots in cylindrical shapes. During the melting process, it is ensured that all atoms are perfectly aligned in the desired structure and orientation. Furthermore, boron is added to give the silicone positive electrical polarity. 

There are two kinds of solar cells: monocrystalline cells and polycrystalline cells. Monocrystalline cells rank better in terms of efficiency in converting solar energy into electricity, and hence, the price of monocrystalline panels is higher than that of polycrystalline panels. 

Polycrystalline cells, on the other hand, are manufactured by melting several silicon crystals together. They can be recognized by the shattered glass look given by the numerous silicon crystals. 

After cooling down the ingot, grinding and polishing are performed, so that the ingot is left with flat sides. 

Step 3: Wafers

Wafers are derived by slicing the silicon ingot into thin disks. This process requires the use of a wire saw for precision cutting. A wafer is as thin as a piece of paper. However, since pure silicon is shiny, it can reflect the sunlight without absorbing any. In order to reduce the loss of sunlight, an anti-reflective coating is applied on the silicon wafer. 

Step 4: Solar cells

The wafers are then converted into solar cells capable of converting solar power into electricity. The wafers are individually treated and metal conductors are added to each of their surfaces. Because of the addition of metal conductors, the wafers get a grid-like matrix on the surface. This ensures the conversion of solar energy into electricity. Moreover, the coating also facilitates the absorption of sunlight and reduces the loss of sunlight because of reflection. 

Further, phosphorus is diffused in a thin layer over the surface of the wafers inside an oven-like chamber. In this way, the surface is charged with a negative electrical orientation. The use of boron and phosphorus gives rise to the positive-negative junction, which is crucial for the proper functioning of the individual solar cells.

Step 5: Cell Cutting

With the help of a laser cutting machine, solar cells are cut out. The size of a cell is determined on the basis of the wattage of the panel. This process is skipped for full cell size modules. 

Step 6: Stringing Process

The stringing process is a fully automated process. Stringing involves joining the cells together to place them in a panel. A good quality panel uses a cell of size greater than 38 mm. Solar cells are joined together with the help of soldering. The upper side which faces the sun, and usually comes in a blue/black color is the negative component, while the bottom side, which is white in color, is the positive component. 

Step 7: Solar Glass

Once the stringing process is complete, the machine transfers it to a section where tempered glass is applied to the panel. The tempered glass already comes with a layer of ethylene vinyl acetate (EVA). 

Step 8: Visual Inspection

 A technical inspector examines the cells for any fault or an error in the stringing process. 

Step 9: Taping

In this step, a technician tapes the solar cells into a matrix alignment. 

Step 10: Connection

Connections between the cells are soldered together. At the same time, any excess material is cut out and removed.

Step 11: Insulate Module Connection

The connections are then insulated by using a back sheet and EVA encapsulation. This is done in order to protect the module for dust and moisture. 

The next step consists of insulating the connections by using a back sheet and EVA encapsulation. This process protects the module from any dust and moisture.

Step 12: Mirror Observation

In this step, the module is checked for any dust particle, color mismatch, and so forth. 

Step 13: EI Testing

EI testing is the abbreviation for Electroluminescence testing. In this step, the solar module is scanned in an EI machine, in order to identify any dead or low power cells, short circuit cells, cracks, etc. In case the module has any such error, it is sent back for fixing the error. 

Step 14: Lamination Process

The lamination process involves laminating the module at a temperature of 140 degree celsius. The laminating process approximately takes 20 minutes. Following lamination, the modules are left for 10-15 minutes to cool down. The next step is carried out only after they cool down to reach room temperature. 

Step 15: Trimming Backsheet, Frame Cutting and Frame Punching

In this step, the excess material of the back sheet is cut and removed to offer perfectly shaped modules. Frame cutting, on the other hand, involves cutting out frames of different sizes for bordering the panels. Following this, holes are punched into the frame for mounting and grounding the panel. 

Step 16: Sealant Filling / Framing

Sealant is attached to the solar panel to protect it from air, dust and moisture. It also helps the module firmly attach to the frame. Once the frame is fixed to the module, the module is sent back to the framing machine, where it is punched to ensure that it is permanently attached to the frame. 

Step 17: Fixing Junction box

Using the sealant, a junction box is firmly attached to the module. Following this, the remaining connections are soldered and are left for 10-12 hours for curing, so that the structures are fully dry and attached properly. 

Step 18: Cleaning and Testing

The solar panel is then wiped to remove all traces of dust and extra sealant. The solar module is then connected to check its output current, voltage, etc. and a test report is generated after following all the essential guidelines. A label with all the details is pasted for the benefit of the users. The module is then sent to a quality control lab to test for its insulation resistance. Finally, it is sent for a mechanical load test. 


In this article, we laid down in detail the process of manufacturing a solar panel. A solar PV module might require a high initial investment, but once installed, it can run maintenance-free for years and can lead to enormous savings on energy bills. With the threat of climate change being more persistent than ever before, we encourage more people to switch to solar energy. 

Recently, people have been switching to solar panels to power their homes. Unfortunately, not every house can apply these solar panels. Your house needs to fit several criteria to accommodate these panels on your rooftop and effectively derive power from the sun’s rays. Well, here are some important criteria your house needs to meet so that you can consider fitting these solar panels at the top.

1. Do you own the house?

If you were to install the solar panels, install them in your own house. In most cases, the initial setup cost incurred due to the solar panels is justified by the savings you get each month when compared to the normal electricity bills. If you install solar panels on a rented house, then you won’t be able to enjoy its fruits for a long time.

Another alternative is to ask the owner of the house to be a part of the installation process and pay a certain amount. In this way, you won’t have to burn a hole in your pocket setting the solar panels and still get to enjoy the monthly savings.

2. Are the nearby trees or structures shading your rooftop during the day?

To extract maximum energy from the sun, enough rays must fall on the solar panels. You don’t have to worry if some parts of your rooftop are under the shade sometime during the day. You can still fit the panels in such a way that maximum rays fall on the solar panels. However, it becomes impossible if your house receives shade most of the time.

The sunnier your roof, the better is the energy production. With the right system and the right components, you can easily avoid the little shade problem on your roof, and still, gain the benefits of solar energy.

Once the shade problem is out of your way, it's time to see how much of the sunlight falls naturally on your sunroof. You can find this out either with the help of Google’s Project Sunroof or book an appointment with an expert. He/she would then inspect the orientation of your house, the roof angle, and the effect of the shade available on the solar energy output.

3. What kind of roofing material do you have?

Another important criterion to fit the solar panels on the rooftop is to check whether your roofing material is durable enough to hold it. Solar panels fit like a dream on durable and strong roofing materials such as concrete tile and standing seam metal. Always go for professional help when finding out the type of roofing you have.

Also, check if your roofing needs to be replaced or repaired any time soon. If your rooftop is due for fixing, repair it as soon as possible before fitting the panels. Once the panels are fitted, it will be quite difficult to change the roofing tiles or do the necessary maintenance.

Age of the roof

Solar panels can be fitted onto your roof for more than 30 years and would require very minimal maintenance. If your housing roof is pretty old, it's ideal to replace or fix it before you fit the panels on. Further, the older the roof, the weaker it becomes. Since solar panels are huge and heavy, your roof should be capable of holding them in place. Even when affected by rain and wind, both the solar panels and the roof should stay intact.

Space available on the roof

Solar panels are huge and wide. Your roof should have enough space to hold them effectively, without causing overcrowding. In some cases, when the roof is small, the consultant would suggest that you go for partial electrification using solar energy. Most residential buildings require at least ten solar panels to supply all the energy needed for that house. If your roof has more chimneys, windows, and other irregular structures, it becomes quite difficult to place the solar panels effectively.

The tilt of the roofing

It's easier to install solar panels on a flat roof, but the problem is it requires a lot of space. Even then, flat roofs yield better output when compared to steep roofs. It's quite difficult to install those panels on steep roofing, and the output would still be below. Thus, as a rule of thumb, a tilt that varies between 30 to 45 degrees is optimal for installing solar panels.

4. What kind of climate prevails in the locality?

Solar energy can be generated in most climatic conditions. If you were to install high-efficiency solar panels, then it can convert both the direct and indirect sun rays into useful energy, and these panels work even on cloudy days. A solar professional will help you determine the amount of energy the panels can generate based on climatic conditions and other factors.

5. If not a roof, is there land available for installing these panels?

If your roofing isn’t compatible of withholding these solar panels, you can consider any flat-lying areas nearby your house. With ground-mounted solar panels, the problem of space constraints doesn’t really matter. You can place the solar panels in the perfect tilt and in a way that it receives maximum sunlight.

However, there are a whole lot of complications and dangers to the solar panels compared to the roof-mounted ones. You can also fix these panels on your car porches or any other shed owned by you.

6. Does the government offer any incentive for switching to solar energy?

Before you install solar panels, make sure they comply with the policies set by the local body in power. In some places, you can sell the excess energy generated by the solar panels and get some incentives from the government. This increases your monthly savings, and you can easily recover the cost of installing these solar panels.

7. The setup cost of these solar panels

If solar panels and the usage of solar energy are quite popular in your area, the chances are that the cost would be more affordable and doesn’t break your back. If it's quite expensive to install solar panels, then you might have to reconsider it as it takes a lot to recover your initial investment.

The cost of setting up the solar panels usually depends on the availability of the suitably sized solar panels, labor costs, and the difficulty level of fixing it up on your roof.

Wrapping up...

Solar energy is one of the cleanest forms of energy that can be easily harnessed and used without requiring much-converting equipment. It's quite popular in households and helps you save a lot per month. With that said, installing solar panels in the wrong areas will only incur more loss than savings. Thus, it's safe to go to a solar consultant and get your house checked professionally to decide if it's suitable for accommodating those solar panels. If you get the green signal, you can go forward with the installation process. If it's otherwise, then you can consider alternatives, such as fixing the panels in the open area or on raised structures nearby.

Do you want to want to be in complete control of the energy that is used in your home? Do you want to use energy that is not only pocket-friendly but also environment-friendly? With this article, we will guide you in your journey to reach energy independence using solar energy. 

Over the last few years, solar energy has become a sought-after solution for sustainable and healthy living in most countries. We think that the first step towards gaining energy independence is by installing solar products like solar panels, solar batteries, etc. at home. This will allow you to generate your power instead of relying on external sources. 

You will hardly have to pull any electricity from the grid if your solar panels meet your energy requirements. The result of a balance between the renewable energy that you produce and that you consume will lead to a net-zero energy bill. Let us learn further how to be energy independent with solar energy!

Go Solar For Energy Independence

Have you been worried about the increasing power consumption at home and the excessive hole it is burning in your pocket? Do you think it’s finally time to go easy on the environment and stop exploiting mother nature by reducing your carbon footprint? It’s never too late to bring about all these positive changes in your style of consumption. Simply switch to solar energy and run all your household appliances on natural light. 

Use Natural Light For Energy

Appliances like lights usually run only at night time while others like your dishwasher, microwave, refrigerator, and laptop are devices that run at a time of your choosing. With solar panels, you can generate and save up energy during the daytime and use it throughout the day. Even the excess electricity can be used to run various appliances in your home. 

The advantage of solar energy is that even when the lighting conditions are relatively low such as on a cloudy day, the panels can generate a sufficient amount of electricity. You can install a low-cost power meter that is linked to your smart meter to generate enough excess energy. Some brands might also display the excess electricity generated. 

Become Energy Efficient

Being energy efficient does not mean using all the home appliances at a minimum level but using electricity in such a way that no extra watt goes to waste. It is how you use your energy in smarter ways. According to me and many experts, an energy-efficient home does not require a large solar power or a complex energy storage system. 

There are many ways in which you can reduce your energy consumption and that does not mean returning to the dark ages. 

Home Energy Storage- Lite

With most families having members that work through the day, the maximum energy is required post-work during the nighttime and during weekends. This mismatch can be resolved by installing a smaller solar battery that can be controlled as per your time shifts. A home energy storage system ensures that solar electricity is not exported to the main grid. 

This will also avoid the hassle of purchasing electricity for the appliances in your home during peak consumption hours. You can charge the small battery during the day and use it to power your devices efficiently at night. 

Home Energy Storage- Robust

Undoubtedly, a larger battery system will help in your efforts to maximize energy independence and self-sufficiency. It need not be as large or costly as a true off-grid system. A battery is sufficient if it can be used to generate electricity during the winters or bad weather conditions. While a full grid system is expensive and might be difficult for you to access now, solar energy technology is rapidly evolving and prices will reduce quickly. 

Until that happens, get yourself solar panels that you can afford since that is better than no solar energy at all. 

Benefits of Energy Independence

We all love freedom and it is something we aspire to achieve with age. Is freedom or independence something you have thought about with regards to your energy consumption patterns? While I have mentioned most of the benefits of energy independence in this article already, I feel it will be helpful to put them all together under one heading. So let’s see what are the benefits of energy independence: 

Do I Need A Solar Battery If I Am Not Off-grid?

As someone who manages the household and takes care of expenses, you must be aware of what can be done in case your existing solar system generates excess energy. There are quite a few options for you to avail yourself of in such a case. You can either exchange the excess photovoltaic energy for net metering credits or store the excess energy in a battery to be used for emergency purposes. The option of doing both also exist. 

If you transfer excess energy back to the utility company, you will be rewarded with credit. I will suggest a wonderful and efficient idea that you can use. It is common knowledge that during the daytime, the price of energy is the cheapest at utility companies and it increases a great deal during peak hours. You can create a grid arbitrage to turn the situation in your favor. 

You can use the utility energy during the low-cost hours during which your panels get charged and then use the stored energy during the peak hours. You can then sell the excess energy to the companies and earn yourself credits. Such freedom in choosing how you manage your energy is a boon and you must make use of it.

Why Go For Loom Solar Panels?

There are quite a few reasons for choosing Loom Solar panels and we will discuss them briefly in this section. It will tell you about the basic features that a Loom solar panel provides along with the advantages they have over other solar panels. By the end of this section, you will be as convinced as I am regarding the great quality and performance of Loom Solar panels. 


1. Efficiency

Loom Solar panels are made of mono PERC cells that make them 20% more efficient than regular solar panels. The mono PERC cells are a part of the latest cell technology that ensures optimum generation of electricity even when the lighting conditions are low or the weather is cloudy. 

Compared to monocrystalline cells that are used in the majority of commercial solar panels, the mono PERC cells have a higher energy density per square foot which facilitates increased light absorption. With such great efficiency and conversion capacity, Loom has won the hearts of many solar panel users in India. 

2. Durability and Build

Loom solar panels are made of silicon cells that do not deteriorate easily. They last for a long time and that is why you will find the company providing 25 years of on-site warranty on its solar panels. They usually last over 30 years and save a lot of your money in the process. The panels have been built to resist Potential Induced Degradation (PID). 

3. Module Size 

You will find small-sized Loom solar panels that will not occupy much space on your rooftop. However, a smaller panel will also cost you more because of the better features. 

4. Frame Thickness 

Other than the quality of the solar cells used, the thickness of the frame is another factor that affects the overall build of any solar panel. Most solar panels including the Loom solar panels have a frame thickness of 30-45 mm and it is guarded by an aluminum structure that can withstand heavy snow loads and harsh weather conditions. 

5. Connecting Wires 

To make an array, solar panels are connected either in series or  in parallel lines. Multiple solar panels are connected in an array and hence, a solar panel must be accompanied by at least a 1-meter wire along with an IP 68 junction that is waterproof and dustproof. Loom solar panels offer all this and much more. 

6. Unbreakable Glass 

Solar panels also come with unbreakable glass for support. The folding solar panels come with foldable glass that has very little chance of breaking. 

Benefits and Advantages:

One of the most important factors that prove the worth of any solar panel is its capacity and effectiveness. The Loom Solar panels undergo extensive testing systems that include optic, mechanical, and electrical tests. Only after they pass these tests are they approved to be sold in markets. You and I therefore have access to the best quality solar panels in India. 

The Loom Solar panels are certified by both ICE and MNRE which are the two most important solar authorities in India. These solar panels require less maintenance since they are mostly dustproof and resistant to PID which also ensures durability with enhanced efficiency. Wouldn’t you like to save on electricity bills without having to do any cleaning work at all? 

You can also save a lot of money in 30 years by using these panels as they are 20% more efficient. The initial cost of investment and installation might be a tad higher but once that part is over, you can relax and see your savings rise. The loom solar panel price will leave you impressed and wanting to switch to solar panels immediately. 

Lastly, the government offers a high amount of subsidy on solar panels in India up to 40% on grid-connected rooftop solar. However, this subsidy is not available on battery-connected solar panels. You must check out the state-wise subsidies assigned to solar panels to know about the exact subsidy that your state government offers. 

Where Can I Buy Loom Solar Panels?

Solar panels have become one of the basic units for generating electricity in an environment and a pocket-friendly manner in the current era. You can purchase Loom solar panels from the official Loom Solar website. The website offers all the information that you require to choose the best solar panel and check out the specifications. You will also find all the information in their information catalog. 

Other than the official website, Loom also has distributors spread out across the country. You can find one near your location and physically visit the showrooms to check out these solar panels. Various other e-commerce websites sell these solar panels as well. Thus, accessing and purchasing the Loom solar panels is no big deal. 

What Information To Provide While Buying Loom Solar Panels?

The information required to provide while buying Loom solar panels is pretty much the same as anywhere else. You must provide the seller with basic details like identity and address proof. There might be some specific permission that you might require depending on the locality you inhabit. It is best to contact the local authorities regarding this and sort out the matter. 

How To Install Loom Solar Panels?

Before you buy solar panels it is best to have some knowledge about the installation process. You must get a professional to install the Loom solar panels for you instead of trying to install it yourself.  Even a tiny mistake could lead to a loss of power and lessen the overall efficiency. Depending upon your location, the standard cost for installing solar panels ranges between Rs.10-rs.15 per watt. 

The first step of installation includes figuring out the direction and angle of the solar panel. South-facing panels absorb maximum light and can generate higher electricity. If the building has a blockage in the south, you can try east or west as well. Anything but the northern direction will work fine. 

The solar panel angle must be in congruence with the latitude of your location as that will generate maximum efficiency. Once these crucial decisions are made, the next step is to assemble the solar panels. The third step encompasses the electrical wiring using MC4 connectors. These universal connectors can be connected to any type of solar panel. 

After these steps are accomplished, you must connect the solar panel to the solar inverter. Connect the panel’s positive wire to the positive terminal of the inverter and the negative wire of the panel to the negative terminal. For overall functioning, you need to connect the solar panel, solar battery, and grid input to the solar inverter to produce electricity. 

Once all the connections are made, you need to switch on the mains. This will start the inverter using the solar panels and the grid. Ensure proper earthing of your solar system as it protects the system from overload, directs excess electricity to the ground, stabilizes the voltage, and prevents accidents. 

Frequently Asked Questions 

1. Do solar panels work during the monsoon?

Due to cloudy weather which creates a low lighting condition, the solar panels might generate comparatively lesser electricity during monsoons. The simple rule for all solar panels is that the more the sunlight, the better the efficiency. However, with the mono PERC cells used in Loom Solar panels, you need not worry about monsoons as the panels work extremely well even then. 

2. What is the average lifespan of a solar panel?

If you have spent a significant part of your life living in a part of India that is prone to power cuts, you know the importance of power backups. For the longest time, Indians relied on propane, diesel, and natural gas-powered generators but the wind is blowing in a different direction now. People are realizing how efficient solar batteries can be for this purpose and they are slowly shifting to solar batteries for their homes or offices. 

The awareness about solar power is increasing among Indians which is why they are opting for eco-friendly and pocket-friendly backup options like a solar battery. Contrary to popular belief, you do not need to install a solar system in your home to use the battery. The solar battery can be set up as a standalone device that generates electricity whenever there is a power cut. In this article, we argue why a solar battery is better than a generator. 

Here are a few reasons

1. A Solar Battery Is Quiet:

If you have generators at home or you have used them at some point, you will be familiar with the horrific loud sound that they make. This incessant noise lasts for the entire duration of the power cut which might last anywhere between a few hours to a few days. While one can tolerate the noise for a few hours, it can disrupt your work and disturb others in the family as well. 

On the other hand, a solar battery is completely quiet. Even if you’re standing next to the device, you will not be able to hear any sound coming from the battery. This is the best device to go with if you are looking for a low noise solution to power outages. 

3. A Solar Battery Is Clean:

When taking into consideration the health of yourself and your family, a solar battery is the right option to go with. Generators emit dangerous chemicals and gases that can cause immense harm and lead to various physical ailments in the long run. For example, diesel generators emit carbon monoxide, nitrous oxide, particulate matter, etc. Even generators that run on propane and natural gas emit harmful gases which if inhaled repeatedly can cause an intense level of damage. 

Solar batteries run on naturally absorbed sunlight which is then converted to energy that fuels the battery during power cuts. There is hardly any harmful gas present in it and the little that is there is sealed so that there are no emissions that could potentially cause ill-effects. 

4. A Solar Battery Is Small:

 The most commonly installed generators in homes tend to take up a large area of space. They occupy a large footprint that can be bothersome if you do not have a space crunch at home already due to other devices and things. You might require a large concrete pad to house such a generator. Smaller, portable generators are available in the market now but they are not ideal for the needs of a home. 

Solar batteries can be mounted on the wall and hence, require no extra construction for the setup. They take up only a few inches on the wall and can be placed just beside the solar equipment or any other garage devices. 

4. A Solar Battery Is Instant-On:

When there is a power cut in your area, the generator will always take a few minutes to cycle up and get your electricity going again. This delay can result in an inconvenient and possibly dangerous temporary blackout. Your children might be scared, people may trip and fall, clocks and devices might reset; overall, there can be unnecessary duress and stress. In the case of a portable generator, the delay can last for a longer time as the generator has to be started manually. 

Solar batteries are instant-on which means that as soon as the current goes, your battery will power up all the electrical appliances in your home instantly without any delay. All of this will happen in the blink of an eye which just goes to show how much more efficient solar batteries are when compared to generators. 

5. A Solar Battery Is Reliable:

A generator requires maintenance every month to ensure that all the components are lubricated and operate properly. Most homeowners get it serviced every year by a professional to ensure it works properly and lasts for a long time. All this requires a lot of investment financially in addition to the hassle of cleaning the battery. 

Solar batteries require no maintenance whatsoever. It will provide you with top-class service all your life without you having to worry about lubrication or servicing. However, it is advised that you clean the surface of the battery from time to time to ensure that it runs well. Trust a solar battery to come to your aid in a moment. 

6. A Solar Battery Is Natural Disaster-Proof:

Many parts of India are prone to natural disasters like earthquakes. In the wake of one, the local utility company is required to shut off the natural gas service to avoid fires and accidents that can easily take place from the gas. If the fuel supply is shut off during an earthquake and the electrical lines ruptured, you will not have access to light for a long time.

Solar batteries do not run on such fuels and hence, they are safe to use even when there are natural disasters in the area. 

7. A Solar Battery Can Run Indefinitely:

Generators are dependent on the amount of fuel available for their proper functioning. It will stop operating and you will be out of a power backup once the device runs out of propane, diesel, or natural gas. It is important to mention here that natural gas generators are fed by an underground line that does not get exhausted and hence, these generators do not run out of fuel except for when there is a natural disaster. 

Solar batteries, on the other hand, can run indefinitely without any hassle. The battery only requires recharging itself and once that’s done, your battery can function without grid power for an indefinite amount of time. 

8. A Solar Battery Saves You Money:

A generator is useful to you only on certain occasions when there is a power outage. Even if that is for a total of 3 days in a year, it amounts to less than 1% of the time. Because you are investing tonnes of money in buying and installing a generator, it makes no sense to use it for such a short period. 

Solar panels and solar batteries run every single day of the year. It helps you save a lot of money on your monthly electricity bills. They assist you when you have power and want to save on the bill and also assist you when you do not have power. 

9. A Solar Battery Enables Energy Independence:

It is becoming an increasingly appealing idea to produce your energy and become completely energy independent. You no longer have to rely on the electric grid to generate power which is the case with generators. Solar batteries enable you to produce, store and use your electricity. This completely reduces the dependence on the local utility. 

10. A Solar Battery Can Be Free:

Generators are not very intelligent devices as they have no interoperability with the electric grid. It makes no difference if you have a generator or not as far as the electric utility is concerned.

Solar batteries are smart devices that can generate and activate power the moment it is required. This is an intriguing quality that appeals to both homeowners as well commercial establishments.. Solar batteries have become increasingly affordable than generators due to these features. 

Frequently Asked Questions

1. How can I make a solar battery last longer?

There are multiple methods that you can use to make your solar battery last longer. You can rotate the batteries periodically, use large battery interconnect cables, charge the battery properly, allow gassing and boiling, and enhance battery equalization. These methods have a shot at increasing the lifespan of the battery by a few years. 

2. How can I tell my solar battery is bad?

Short circuits can result from broken or loose terminals. 


Solar batteries have become a viable option to install in your home as a power backup. This brief article has provided you with some of the most important reasons for which this is the case. We hope that this convinces you to go for a solar battery that will ensure instant power supply whenever there is a power outage. 



Solar panels have gained popularity in India in recent years as people are gradually realizing how cost-effective and environment-friendly they can be in the long run. Most households and even businesses use 300-watt solar panels or more in India. Choosing the right solar panel for your solar system can be an exhausting process, especially when you have a fixed budget in mind. 

This article will help you figure out the best 300-watt solar panel price in India so that you can select the panel that fits your budget. Along with the prices, we also provide you with other important information you need to buy a 300-watt solar panel. 

How Much Can A 300-watt Solar Panel Run?

A 300-watt solar panel has the capability of a battery with300-watt power. It is recommended by experts that you use 12-volt batteries so that that energy can be stored efficiently and can be used at a later time. Even the appliances that you use should be of the same voltage as the battery, that is, 12 volts. Only this way can the efficiency and benefits of the solar system be maximized. 

Once the solar panel is charged for a few hours, you can use it to run a wide range of electrical appliances like fans, TV, LED lights, and so on. If you plan on using the solar panels just to power a single appliance like a fan, it will run for a longer period as the pressure on the solar system will not be as much. However, if you plan on using all the electrical appliances that have been mentioned here, you cannot expect the system to run for a very long time as soon you will have to recharge the battery. 

Fans tend to consume more power than LED lights. Hence, it is best to avoid using other electrical appliances when you use a couple of ceiling fans coupled with a few LED couple lights. This will permit the fans and lights to run for a few more hours than usual. Be mindful of the fact that a single 300-watt panel can only run a maximum of 300-watt appliance(s). To run a load more than that, you require multiple solar panels. 

A single solar panel will provide energy only for a couple of hours and if you need it to run for the whole day, then install more than one panel. For example, if you install more than 6 solar panels on the rooftop, it will be able to run almost every appliance in your home smoothly. LED, TV, ceiling fans, refrigerators, etc. can all be run simultaneously with this many solar panels. Installing multiple panels will also result in a sharp drop in your electricity bill. 

For a business or office installation, you will need to use more than 50 panels for complete support to all the appliances in the building. If the office has multiple floors, the number of panels will increase as per the increase in requirement. 

Factors To Be Considered Before Buying The Best 300-watt Solar Panel

  1. Types of 300-watt solar panel:

The different types of 375-watt solar panels are based on two factors- the mounting type, and the technology used. 

  1. Mounting Type- There are two ways in which solar panels are mounted; it is either mounted or fixed on to someplace. The fixed solar panels are the conventional panels that are fixed on the rooftop and supported by a corrosion-resistant aluminum frame. These panels are still commonly used for many purposes like utility, and in both commercial and residential settings. 

On the other hand, we have flexible solar panels that are portable appliances. These have taken over the market today because of the ease with which you can move them around. 

  1. Technology- The price of a 300-watt solar panel is also based on the technology it uses; whether it is a monocrystalline panel or a polycrystalline panel. The former have an efficiency rate of 18-25% while the latter rate only 17-20% on the efficiency scale. While the former are more durable than the latter, they are also more expensive because of the superior quality material used. 

2. Weight:

The weight of the solar panel is yet another crucial factor you need to consider before buying one. This is so important because it directly impacts other factors like how portable or heavy the solar panel is. If you plan on moving around the solar panel frequently, it is best to opt for something lightweight and ultra-thin. The flexible or movable solar panels weigh around 2 kgs and hence, can be easily moved around the place. 

Even the chance of any major damage is reduced in the case of lightweight solar panels when there is a storm. The pressure on the rooftop is also reduced during these times. 

3. Dimensions:

The dimensions of most 300-watt solar panels are the same with a few moderations here and there with regard to the measurement. The power generated by the solar panel determines to a large extent the dimensions of a solar panel. A 300-watt solar panel is medium-sized which is suitable for both residential and commercial purposes. However, as mentioned earlier, if you want to run multiple appliances on the solar panels then you will have to install multiple solar panels. 

4. Price:

This is the most important aspect of the solar panel with respect to this particular article- the price of a 300-watt solar panel. You must have a budget in mind before you set out to buy a 300-watt solar panel. The price of a 300-watt solar panel depends on the type of panel you are purchasing as well as the brand from which you plan on buying it. Most of these solar panels are available at an approximate price of Rs. 8000 in India. 

5. Efficiency:

The last factor we want you to look into is the efficiency of a 300-watt solar panel. With installation in residential areas, space becomes a major issue. You must make use of every inch of the space available to you because the efficiency of a panel depends on its size as well as the number of panels you can install. Try to choose panels with higher efficiency as they tend to be more pocket-friendly and effective in the long run. Do not compromise on the quality and efficiency of the panel while trying to find something that fits into your budget.

Installing a solar system is a big step, and you should be thorough with your research and analyses before investing in it. Diving into it headfirst is probably not the best idea since solar designs are much more complex than they appear. 

Things to Keep in Mind Before Going Solar 

1. Cost: There are a few things that determine the overall cost of your solar installation. You need to factor in the size of your home and how much energy you use. Apart from that, there are plenty of solar panels to choose from. In India, some of the leading solar panel manufacturers include Tata Power Solar, Vikram Solar Pvt. Ltd., WAAREE Energies Ltd., EMMVEE Photovoltaic Power Pvt. Ltd., and Moser Baer Solar Ltd. 

2. Your roof: If you’re installing solar panels on your roof, it needs to be inspected to make sure it can withstand the panels’ weight. You can discuss with your installer or contractor whether your roof will be affected by the installation. 

3. Residential location: Solar panels need about four hours of sun exposure per day, so if you live in an area where enough sunlight is available, you’re good to go. The more sun exposure, the greater is the solar panel efficiency. 

4. Source of electricity: Whether or not you want solar power to be your only energy source is totally up to you. You can choose to harness some energy through solar panels while also staying connected to your city’s electricity grid. People living in low sunlight areas mainly consider this. 

5. Warranty: There are two types of warranties – product and performance warranty. Warranties are dependent on the manufacturers, so there might be exceptions to what different warranties will cover.   

6. Right contractor: Just like any other installation in your home or office, you need the right installer or contractor for your solar power system. If installed incorrectly, your roof could be damaged, and panels’ production output and lifespan can reduce. It’s also helpful to consult people who already have solar panels installed about their experiences. 

7 Common Mistakes to Avoid 

1. You’re Not Necessarily “Going Off The Grid.” 

It’s a common misconception to think that upon installation of a solar power system, you will disconnect from your city’s electricity grid. That would be a mistake. 

Solar panels allow you to generate your energy, and you can stop paying for power from these grids. However, you do need a way to store the energy generated by solar panels for later use. With access to power lines, you can store this energy in the electric utility grid. 

So, what you’re looking for is a grid-tied solar system rather than an off-grid solar system. This system allows you to generate power for your home and sell access electricity to the state government. You also get five years of payback time and free electricity for the next 20 years. 

Off-grid solar power systems do not have access to power lines, so they need another method to store energy. This is where battery banks come in. Batteries are expensive and mandatory for the off-grid system. They eat up much of the return on investment (ROI) from solar panels.

Therefore, you can avoid a very costly mistake by staying connected to the grid. Installing solar panels does not mean being completely independent of the grid. So, if your property has access to power lines, a grid-tied solar system is the best way to go. 

2. Misdesigning the System 

Designing a proper solar power system with proper sizing is more complicated than it looks on the surface. This is why it’s best to consult with manufacturers and installers about designing and planning the system. 

If you think simply researching enough to buy panels that cover your energy usage is all, then you’re ignoring a lot of crucial factors. Climate, panel orientation, natural efficiency drop, shading, and other factors determine your system’s total output. 

Some factors you can consult a solar panel technician on are:

1. Efficiency: Solar panels have an efficiency rating, and they suffer a 0.5-1% efficiency drop every year. It means 20 years after installing them; they’ll be 10-20% less efficient. So, while designing your system, you should account for this loss of efficiency by designing a little extra headroom. To do that, you could add a few extra panels. 

2. Weather and location: Manufacturers test solar panels in ideal temperatures, ranging from 20-25ºC, inside factories. However, in the real world, your system is exposed to much harsher weather conditions. High temperatures can negatively affect the energy you generate. 

Your location determines the number of sun hours you get. “Sun hours” refer to the amount of time the Sun is in the correct position to generate maximum energy. In India, the average sun-hours range from 5-8 hours per day. However, depending on the state, the exact amount would affect the sizing of the system.

3. Voltage: While inverters and charge controllers have maximum and minimum voltage input windows, panels and batteries have voltage ratings. Your system’s design depends on the voltage requirements of the equipment being used. Temperature also affects the voltage and system performance. Not having the proper voltage from solar panels or battery banks can lead to poor system performance and damaged hardware. 

4. Battery Bank Sizing: If you’re using the off-grid system, you’ll require a battery bank. A common mistake that happens with battery banks is mismatching the battery bank with the charging source. Your battery should get enough power supply to keep it charged but not too much power so that it doesn’t overcharge. 

While overcharging can damage the batteries, undercharging can have an even worse effect. Some batteries need to be fully charged daily, or they run the risk of failing prematurely. 

3. Solar Power does NOT Prevent Outages 

Even though you’re generating your own energy, you can expect your electrical appliances to stay functional even during a power outage. This is primarily for grid-tied solar systems. While the panel generates the power, it gets stored in the electric utility grid. So, when the grid power goes out, yours does too. 

The only way to remedy this situation is to have a grid-tied system with a battery backup. When the power is on, the standard grid-tied system is functional. When there’s an outage, the backup battery bank takes over. It does cost a bit more, but you can rest assured with the backup, especially if you live in an area with extreme weather conditions. 

4. Going Solar is a Bad Investment  

Agreeably, investing in solar energy isn’t cheap. It’s a big commitment with a large upfront sum payment for the installation.  However, electricity from the power company isn’t cheap either, and it’s only going to get more expensive with the exhaustion of nonrenewable resources. 

In the long run, installing a solar power system is much more beneficial. Most grid-tied systems pay for themselves and make you profit over the warranty period. 

In India, on average, a solar system (with a battery backup) of up to 10kW is installed in homes, known as the residential solar system. The investment is around Rs. 1,00,000  per kW. Installing a solar system in such a residential setup could lead to annual savings of up to Rs. 8,400. The investment is expected to have a payback period of approximately 10-11 years, and return on investment (ROI) will be around 8%. 

Commercial solar systems (grid-connected), such as those installed in hospitals, factories, offices, resorts, etc., require 25kW capacity. The investment is around Rs. 50,000 per kW and annual savings are around Rs. 14,000. The investment is expected to have a payback period of approximately 3-4 years, and the return on investment is around 28%. 

5. Leasing 

Investing in solar power is great as long as it’s your own system. Leasing the system from a third-party can diminish the value of the investment. Solar leasing wasn’t very popular in India, but now more solar companies are entering the leasing space. Hero Future Energy, SolarTown Energy Solutions, First Green, and SunAlpha Energy are some of them. 

The problem with leasing is that the third-party lender owns the system, so they’re eligible to claim the incentives. You do not get the incentives, and you will also have to pay a premium rate for leasing and the interest on it. It can be more expensive than financing your own system. 

Leasing also makes it difficult to sell your home if you’ve decided to move. It limits the number of potential buyers for your home. 

6. Lack of Proper Planning

Not planning while designing your solar power system can give rise to problems in the future. The common mistake made while planning a solar power system is thinking about the present needs. People often don’t think about how their needs might change in the future. 

You could have children, build more rooms in the house, buy an electric car, or start a business at home. All of this would increase energy consumption. If you don’t know the factor in these things at the time of your planning, you won’t be able to expand your system in the future. 

Make sure you have the space to expand the current installation. If the panels already cover the entire roof, where will you place more panels in the future? Another thing to keep in mind is whether the system is designed to expand. It’s not as simple as just adding more panels to expand the system. You need to ensure that other parts like the inverter are sized to match. 

For an off-grid system, you also need to think about battery sizing. Your existing battery bank might not be expandable. Lithium battery banks can be expanded, but lead-acid batteries have limited options. This is because new lead-acid batteries tend to absorb the characteristics of the old ones. So, the new batteries can age prematurely. 

7. Building a Piecemeal System

Recycling, reusing, and thrifting are excellent practices, but not so much when it comes to solar system installation. If you’ve acquired different parts of the solar system over time from different sources, you cannot just slap these parts together and build your solar system.  

Just like with other electronics, you need compatible parts for building the solar-powered system. Otherwise, you might have undersized inverters, differently-sized panels, components that have different connectors, a power center with missing essential components, among other problems. 

You’re not building a solar-powered Frankenstein monster. Piecemeal systems are bound to turn into a disaster and a waste of resources. Unless you properly plan and design your system and acquire the parts after proper research, you won’t be able to build a functional solar system. 

Bottom Line  

You might have realized by now that installing solar panels is not an easy affair, but it’s necessary in today’s times. The best way to go about it is by conducting thorough research and consulting experts and technicians regarding design plans and other variables. When you’re making this big an investment, you need to make sure you get some experienced set of eyes to look at your plans. It will help you identify and eliminate some costly mistakes before you dive in. 

Solar panels are an ingenious way of reducing expenses on energy bills. They are an eco-friendly, green alternative to conventional energy sources, and can help reduce your carbon footprint. In recent times, rooftop solar panels have become popular with all kinds of consumers, thanks to their easy availability and diminishing costs. However, a serious issue that many consumers face during the installation process relates to roofing problems. Many times, the roofs of the buildings are damaged or aging. As such, they are simply not strong enough to bear the burden of the new solar system

In this article, we will discuss the challenges related to roofing during the installation of a solar PV system. We will also offer solutions to these problems. Going through this article thoroughly would reveal whether you should replace your roof before installing solar panels.  

The Importance of Roof for a Solar PV System 

While researching on solar panels, you get to know about different brands of solar panels, the components used in a solar PV system, etc. But very often, the research articles tend to overlook the question of roofing. However, your roof is one of the most essential components of your solar PV system. 

This is because the roof of any building receives the maximum sunlight. Some homeowners might choose to install their solar panels on the ground, but that would require a lot of space. Certainly, most people would not like to waste the limited space available for the garden and the lawn around their house by setting up solar panels. As such, the roof of the house is the best place to install solar panels. 

People often fail to realise that their roof is not simply a collection of tiles or shingles attached to the top of their house. Instead, it is a complex system that comprises the following things: Roof truss, decking, frame, water barrier, insulation, decking, shingles or tiles. The damage in any of these layers can weaken the structure of the entire roof, thus, making it unfit for installing solar panels. So, how do you know that your roof is not all okay? We shall discuss it in the next section. 

Identifying Roof Damage

The following are some of the common types of roof damage:

1. Loose/broken tiles:

Loose or broken tiles is a kind of damage, which can be observed with the naked eye. You can use a ladder to visually inspect your roof and see if there are any loose or broken tiles or shingles. 

2. Wear and tear of materials:

As your roof gets older, exposure to constant sunlight, rain, hail and snow will wear out many of its components, making it more fragile. Such damages include shingle granules, rust, and bare shingles. 

3. Water damage: 

Water damage is one of the biggest concerns for any roof. The moisture retained by the concrete can seriously affect the structural integrity of the roof. Water damage usually follows a broken component of any roof, such as worn out swalants, torn underlayments, etc. 

4. Standing water:

If your roof does not have a proper angled design, rainwater logging will take place. Usually, roofs are designed to efficiently shunt water off its surface. Thus, if you notice standing water on your roof, it is an indication that there is something wrong. 

5. Pictures and cracks:

Cracks and punctures are one of the most serious forms of rooftop damages, and if there are any visible cracks on your roof, you must get it repaired as soon as possible. 

6. Structural damage:

Structural damages happen only on rare occasions, and they are prone to collapse. Therefore, issues of structural damages must be addressed immediately. 

If you notice any of these things, there is a possibility that your roof requires repairs before you can install solar panels. 

Importance of Roof’s Age

Even if there are no visible damages, it does not mean that your roof is fit for installation of solar panels. An important thing to factor in is the age of the roof. An old roof can be fragile and prone to damage. It might not be fit for the installation of solar panels. The factors that can impact the lifespan of your roof include its materials, the climatic conditions of your area, and how well you maintain it.

In the villages, particularly in areas which experience hot and dry weather conditions throughout the year, roofs made of clay tiles are common, and they can last for a very long period of time. They tend to have a lifespan of about 50 years. Slate and copper roofs can also last for nearly 50 years. Wooden shake roofs, on the other hand, tend to last for about 30 years, offering a slightly lesser lifespan than the clay tile roofs. And finally, we have the roofs made of cement shingles, which tend to last for more than 20 years, without much repairs. If there are noticeable damages on your roof and you have not fixed them over time, the lifespan of the roof may be cut short. Thus, it is important to undertake regular repair works.    

It can be really dangerous to install solar panels on a roof which has gone past its lifespan. This is because worn-out components can make the tiles more vulnerable to cracking. The underlayment, too, becomes much more vulnerable to wear and tear. An old roof will not be able to support heavy solar panels. It will not hold up well to drilling, installing, or racking. Many older roofs were simply not designed to handle the heavy weight of solar panels.  

Thus, before you contact a certified solar PV installer to install a solar PV system, make sure that your roof is not very old. Go through the house building plan carefully and talk to the installer about the specifications of your home roof. If your roof is nearing the end of its lifespan, it is advisable to get it properly repaired or replaced, before moving ahead with the installation of solar panels. 

The Importance of Roof Repair/Replacement Before Getting Solar Panels Installed 

It is true that repairing and especially, replacing the roof of your house is not an inexpensive thing to do. You will have to spend a huge chunk of money on buying and installing solar panels, and roof repairs will only add on to these costs. However, repairing or replacing the roof may be the right thing to do, even if it pushes costs up or delays installation of a solar PV system. The good thing is that today, due to a number of policies devised by governments and authorities at various levels, one gets a heavy amount of subsidy on installation of a solar PV system. In fact, banks, nowadays, offer loans for solar PV systems as a part of home improvement loans. Such initiatives can heavily reduce the burden on your pocket, and can leave you with enough incentives to undertake a repair of your rooftop before installing solar panels. The stronger and better the roof, the longer and more efficiently the solar panels can work. 

If you decide to install solar panels on a fragile roof to cut costs, you will have to address a lot of problems in the future. You will have to remove your solar panels all over again, get your roof redone, and install them again. In this way, the costs are only going to escalate in the long run. Thus, paying for roof repairs before installing the panels, in the first place, will save you a lot of money and lots of headaches. 

In addition, the roof of any building plays an important role in insulating the building. A poorly insulated roof, suffering wear and tear, can make the house extremely cold in the winters, and extremely hot in the summers. Thus, it will require you to use air conditioners and heaters more often, meaning that you cannot entirely depend on your solar PV system for meeting your household’s energy demand. A new roof can make your house energy efficient, and you can use smaller and more affordable solar panels to power your home. 

Besides, a new roof will increase the appeal of your house and increase its value, which is very important if you are planning to sell your house in the future. 


In this article, thus, we discussed the importance of getting your roof repaired or replaced before the installation of solar panels. We listed down all the important reasons for doing so and also, how you can identify roof damage in the first place. In our opinion, you should look for an installer which performs roof repair/replacement and solar PV installation at the same time. By contracting the two activities out to a single agency, you can actually bring down costs.

As the threat of climate change is getting wider recognition at different levels, the transition to renewable energy sources is happening at a much faster pace than ever before. One of the most widely used renewable energy sources is solar energy. 

Apart from powering houses and offices using solar PV modules, solar energy is also effective as an outdoor lighting solution. In this article, we are going to talk about one such lighting solution, namely, solar street lights. 

Traditional street lights use electricity generated using conventional sources to function. Although new, energy-friendly technologies such as LED bulbs, have made street lights more environment friendly, they have not ended their reliance on conventional energy. Solar street lights, on the other hand, are fitted with solar panels and batteries, and it uses the energy trapped from sunlight to function. In this way, it ends dependency on conventional energy sources, leading to drastic cuts in terms of carbon emissions. 

However, choosing a solar street light might be a tricky task. Not only are there too many brands and products to choose from, but they also differ in terms of the specs, features, power ratings, price and so forth. 

Therefore, in this article, we will help you choose the best solar street light in the market. We will review some of the best solar street lights that are available in India, and also list down all the important factors that one must look for while buying a solar street light.

In this article, we have included both all in one and integrated solar street lights in our list of the best solar street lights in the market. 

2. Area To Be Illuminated

The area to be illuminated is one of the most important considerations to make while buying a solar street light. This will depend on your requirements, such as whether you want a street light for a narrow street, or a wide street. Solar street lights are not only meant to be used for illuminating the streets, but also for public street lighting, park lighting, sidewalk lighting, farm and ranch lighting, perimeter security lighting, dock lighting, fence lighting, and residential property lighting. 

For the best results, it is advised that you should maintain a pole distance of 10 to 15 metres, so that there is a sufficient distribution of lights. In addition, make sure that the area where you are installing the light receives sufficient sunlight, and is not covered with tall buildings and branches of trees.

3. Battery Life

This is one of the most important factors affecting the performance of a solar street light. While purchasing a solar street light, make sure that the product uses a lithium ion battery with a good capacity. Further, pay attention to the kind of batteries used. SMF batteries are not really good and they must be avoided. The best option is to go for a solar street light that features a LiFePO4 battery. Otherwise, simply stick to the Lithium ion batteries. 

4. Water Proof 

Since solar street lights are always placed outdoors, it is normal for them to face harsh weather conditions. One of the things that affect any electrical equipment is rain. Thus, make sure that the solar street light you are buying is waterproof. 

Usually, there are three kinds of waterproof certification standards available for solar street lights. They are indicated by their IP rating. An IP55 rated product offers protection against dust and water jets projected by a nozzle of 6.3 mm. IP65 rated products, on the other hand, are able to protect themselves against all kinds of water jets. An IP66 rated product can protect itself against powerful water jets and IP67 rated products are able to protect against underwater immersion up to 1 m depth.

Solar cookers are an ingenious way of cooking food without the use of any kind of fuel. It is an environmentally friendly alternative to traditional LPG-cylinder based or electricity based cooking technologies. Solar cookers share advantages and disadvantages with most other solar-based products. Just like any other solar-based product, solar cookers cannot function or be of any use without sunlight. In this article, we are going to carefully lay down all the advantages and disadvantages of solar cookers. We are also going to discuss the various types of solar cookers that are currently available in the market, as they tend to eliminate the problems which have traditionally been associated with solar cookers. We would urge you to go through this article carefully to find out more about solar cookers. It will be of great help to you if you are considering installing a solar cooker at your own place. 

Advantages of Solar Cookers 

The following are some of the advantages of using a solar cooker:

1. Cost-effectiveness 

Unlike an LPG based cooking solution where you need to spend money every time you get a new cylinder, a solar cooker requires no such recurring payments. This is because sunlight is free and unlimited and hence, cooking on a solar cooker is effectively free. You just need to make an initial investment of installing a solar cooker, and that’s all! 

2. Environment Friendly 

Natural gas is a non-renewable energy source, and if you reside in a hot area, a conventional cooker makes your house hotter while cooking. A solar cooker produces no emission of gasses like carbon monoxide, maintaining a better air quality indoors. Besides, sunlight is unlimited and a renewable energy source. The environmental impact is thus, minimum when you are using a solar cooker. 

3. Nutritious, tasty and hygienic cooking 

Solar cookers make cooking more nutritious, hygienic and tasty. It eliminates the possibility of burning food when you are cooking, baking, grilling or roasting. The latest solar cookers can even direct the sun rays in a more precise manner, thus, offering a better efficiency. Moreover, in baked food, the moisture and softness is retained. 

4. Power cuts is not an issue

Induction ovens and microwaves require electricity to run, and power cuts are a major challenge in India. However, as solar cookers use sunlight to cook food, you do not have to worry about power cuts. 

Disadvantages of Solar Cookers 

The following are some of the disadvantages of solar cookers:

1. Useful only for cooking in the daytime 

The biggest disadvantage of using a solar cooker is that it is dependent on sunlight for cooking. As a result, you cannot cook using a solar cooker at night. Besides, rain, low sunlight penetration, cloudy weather, etc. also serve as impediment to cooking on a solar cooker. 

2. Eye damage 

One needs to be careful while using a solar cooker, as accidental reflection of sunlight into your eye can damage your eyesight. 

3. Requires Backup

It is impossible to be completely dependent on a solar cooker for cooking. You will require a conventional cooker, which can be used when sunlight is not sufficient, or on a rainy day. Besides, with a solar cooker, you need to start cooking early in the day, when the sunlight reception is maximum. 

4. Less Efficient

Solar cookers take a lot more time to cook than conventional stoves. Hence, if you are in a hurry to cook your food, you will have to use a normal stove. Besides, solar cookers are costlier than regular gas stoves. You will also need to find a suitable place in your house to place a solar cooker, where the sunlight reception is maximum. You might also be required to change the position of the reflector, according to the position of the sun. 

Types of Solar Cookers

To eliminate the problems traditionally associated with solar cookers, companies have come up with new products, introducing improvements in technology. As such, commercial solar cookers can be categorised as follows:

1. The Hot Box

This is an insulated square or rectangular box solar cooker, which comes with a glass lid. There are multiple panels, which focus the sunlight’s radiation into the internal side. The flat black colour over it enables a better absorption of heat. 

2. The Parabolic Dish

Parabolic dish solar cookers can attain heat up to 250 degrees celsius. These cookers lack flat panels, and instead come with a parabolic dish or a plate. This dish acts as a lens to focus sunlight at a certain point. These kinds of solar cookers are highly efficient, enabling fast cooking. 

3. The Vacuum Tube Cooker

Vacuum tube solar cooker comprises a pair of tubes. The tube’s heat insulators have a vacuum in between them. It ensures that the heat is reflected on the outer tube perfectly and then gets absorbed by the inner tubes. In this way, it helps reduce cooking time. 

4. The Panel Cooker

Panel cookers use a simple technology. There are more than one panel to fold out sunlight radiation, and in this way, a panel solar cooker ensures an efficient cooking. 


Solar cookers are an environment friendly alternative to traditional cookers and stoves, and they help reduce costs in the long run. However, they come with their set of cons, which you need to be aware of before switching to them. Their efficacy is mostly impacted by weather conditions, and moreover, you cannot completely depend on them. You cannot cook on a solar cooker during the night, as there is no sunlight.

In this article, thus, we pointed out all the advantages and disadvantages of solar cookers. We also listed some of the recent innovations that companies have introduced in their solar cookers, and classified them into four different categories. Go through this article carefully, so that you can make an informed choice about solar cookers. 

Growing environmental concerns, increasing electric bills, and depleting natural resources is an alarming matter of distress. The drastically changing conditions have convinced many to look for sustainable and feasible alternatives for electricity production. 

Till now, the most efficient and lucrative option disposable has been solar power. The Sun, in the form of solar radiation, is the greatest energy provider. It makes sense to harvest the freely available source of electricity as, unlike with fossil fuels or other non-renewable resources, it isn’t going to run out any time soon. 

The almost non-existent environmental risk and the reducing, and in some cases absent, electric bills are incentive enough to see a shift in sources of electricity. So, what’s stopping us? 

Solar Installations- The Problem 

Despite the many benefits and cost-effective outcomes, most people have not decided to convert their channels of power to solar energy. This can be easily justified by the enormous installation costs required to set-up the system that converts sunlight into usable electricity. 

Even though the initial cost of installments is warranted and returned in the form of significantly reduced energy bills, the startup investment is a hard pill to swallow. The expenses deem the whole process unfeasible and ‘out of the bounds’ for the common working man. 

But, global warming isn’t going anywhere. Looking after our carbon footprints is the responsibility of all inhabitants of the world. Considering the lose-lose situation, bank financial institutions have stepped up and are now helping facilitate this conversion in the form of loans for solar installation. The simple solution enables solar installation for homes, offices, etc., and is a stepping stone to a better future. 

Cost Breakdown

Why are solar power plants initially so expensive? The concept of harvesting solar energy and using it as a usable form of work may seem like a simple one, but the actual technology involved is quite sophisticated, hence the expense. 

A basic solar energy system has four primary components- solar panel, solar inverter, solar battery, and panel stand. This is besides the additional solar panel installation requirements and accessories- modules, string inverters, module mounting structure, cables, conduits, earthing electrodes, lightning arrestors, earthing strips, and civil foundations.

The cost of the actual system largely depends on the rates of the modules and inverters employed. It is a given that the more refine and advanced technology would demand a steeper price for the premium quality products. The higher the rates, the better the quality, the longer the system lasts, and the more energy generated. 

The type, models, size, and power of the solar panel system will be decided by the electricity load of a household. With the difference in power comes the price difference, and so the type and amount of loan.

A starter plan may be described as- the total expenditure that includes system design and equipment cost, which accounts for 75% of the solar loan. 10% of the total is for installation and commissioning, regulatory approvals charge 5%,  and finally, the maintenance accounts for 10%.

The rate for a 1 kW rooftop solar set-up can lie anywhere between ₹45,000 to ₹85,000, not factoring in the cost of batteries in the current market. Average Indian household requirements are majorly met by a 5 kW system that produces 20 kWh of electricity on a bright, sunny day and roughly 600 kWh a month. This investment price could be met by a loan of ₹225,000 to ₹425,000.  Additional costs like the construction of elevated structures, strengthening of roofs, and GST are not included.

Loans for Solar Installation

The exorbitant rates of the high-tech pieces of technology necessary to avail the benefits of a solar panel system make the switch to greener energy an unlikely option for most middle-class families. Even if people want to invest in a better, sustainable future, they lack the means of finance. 

Thankfully, government financial institutions, like banks, have offered to support various schemes to help facilitate loans for homes. Besides the government, several private banking options and non-banking financial institutions (NBFCs) have released schemes too. Companies involved in the solar panel business also have tie-ups with particular loaning agents to help their customers make the purchase. 

Buying a solar system is no different than buying any other product, albeit a pricey one. Think of it as purchasing a home or a car. Making these investments has become convenient because of the many schemes, EMI options, and the general availability of loans. 

Investing in a solar system is no different. In fact, solar loans is becoming more and more popular by the day with the increasing need and banks are accommodating this rising traction of customers by offering many options of payment at reasonable solar loan interest rates in India.

What Banks offer Solar Loans?

In India, the first resort for loans of any kind is banks. Many banks offer solar loans that provide top-up plans in the form of home loans and renovation loans. While other banks specifically hand out loans for residential solar rooftop installation. 

These loans have varying solar loan interest rates in India ranging anywhere between 10% to 18% that is decided by the risk profile and the source of income of the customer. The payback period also varies accordingly, starting from 1-5 years that can build up to 20 years.

Some of the choices that are available in today’s market for loaning for solar panel installations are the State Bank of India, Union Bank of India, ICICI Bank, Axis Bank, Kotak Mahindra Bank, Federal Bank, Canara Bank, Indian Bank, YES Bank, IDBI Bank, Syndicate Bank, Punjab National Bank, and Delhi-Cooperative Housing Finance Corporation Limited.

Anyone holding a credit card can easily opt for the EMI option on a solar system, but do debit cardholders have this option? 

About 80 crores of Indians are cardholders, out of which nearly 30 crores people own debit cards. Only 50 lakh people, i.e., approximately 1%, have credit cards that allow them to avail the EMI option on installations of solar systems. So, this makes EMI a less than possible choice in solar installation for most people.

How can you get Loans for Solar Installation? 

Specific loans for solar installation are available by a few loaning agencies, and the purchase can be made via Equated Monthly Installment (EMI). Other choices also include- conventional mortgage loans, no personal security loans, and over-the-counter credit card payments. 

Typically, two ways are followed to sanction loans for residential solar systems- 

  1. Purchase solar panels on EMI 
  2. By home improvement loans

1. EMI with Credit and Debit Card

Credit cardholders have the privilege of availing themselves easy access to EMI payment options for most loans, including the solar system. Debit card users, on the other hand, do not have it that easy. 

In India, 80 crores of people from the population are registered as bank cardholders, of which only 1%, i.e., roughly 50 lakh people, own credit cards. The majority, 30 crores individuals, carry debit cards. 

So, 1% of all bank card owners can consider EMI for loans for solar installation as they do for other consumer durables. Banks like- CBI, Kotak Mahindra Bank, ICICI, Axis Bank, Induslnd Bank, HSBC, Corporation Bank, Standard Charted Bank, American Bank, HDFC Bank, City Bank, SBI Bank, and Yes Bank- have simplified the process of taking credit for specifically for solar installations to be paid back as EMI with zero interest. However, this option is only meant for the parts or accessories of solar installations. 

For debit cardholders, the case is different. The chances of getting loan approval are meager, approximately 0.02%. The approval depends on the bank’s internal database and the cardholder’s records. To check the availability of loans according to the Loan Eligibility Criteria, simply send a text from your registered mobile number and get the necessary details. Here’s how- 

2. Home Improvement Loans

A few banks offer home improvement loans, like the State Bank of India, that can be re-purposed as solar loans. The interest rates vary according to every bank’s policies. The SBI grants loans of up to Rs.1 lakh for home improvement with an interest rate of nearly 8%. 

Home Credit (loan) is a bit more complicated and involves several steps. For starters, a Quotation from a trusted solar company would be required by the bank. Documents will have to be verified by the bank officials, after which the loan may be sanctioned. 

If approved, the bank will proceed to transfer 80% of the total loan directly into the solar company’s account. This may take up to 5 to 7 business days. After the installation is complete and the customer sends a NOC to the company, the bank will finally transfer the remaining 20% to the company account. 

A bank customer can easily be allocated a home improvement/renovation loan to install a solar panel system. The process becomes even smoother if the customer already has a home loan from the bank as the bank would carry the proof of the customer’s credibility in its server. 

In case he does not have a previously awarded loan in his name, he is still eligible to take out a home improvement loan after all documents have been verified and thoroughly vetted.  

Apart from banks, there are non-banking financial institutions (NBFCs) that also finance residential solar installations. Some of these agencies are- Gromor Finance, EFL, Lendingkart, Edelweiss, Bajaj Finserv, and Metafin. Though, unlike banks, NBFC demand much steeper interest rates starting from 13% that may go up to 18% to 24% but do not ask for collateral.

Tax Benefits of Loans for Solar Installation

There are some tax benefits to be considered when debating the mode of payment of financial status while purchasing a solar panel system. 

A working man who receives an annual salary equal to or more than Rs. 5 lakhs can claim tax benefits by announcing their solar system installation as an expense in their ITR. Once a customer’s home improvement loan is passed, he may stake a claim of an expense in his ITR as a deduction from his total annual income. 

Let us consider a potential customer who earns an annual income of Rs.10 lakhs and is interested in investing in a solar system. He decides on a 5 kW power solar panel set-up for his residential building that estimates to Rs.3 lakhs. He requests a home improvement/renovation loan of Rs. 2.5 lakhs. 

The loan tenure will be decided by the bank depending on the customer’s age and finances. This may range anywhere between a year to 30 years. The customer can negotiate his EMI payment plan according to his comfort and convenience. 

If the customer decides to pay an EMI of Rs. 15,000 a month, his annual obligation would then be 180,000. This sub-total amount would be deducted from his total annual income.

To conclude, there are several different options available to an interested customer in solar system installations. From banks to NBFCs, there are many payment methods, interest rates, policies, and types of loans to choose from that would be best suited to their financial conditions. 

A solar charge controller controls the variation in power that the solar panel generates after absorbing sunlight and then charging the battery and operating the DC load. This controller prevents the battery from overcharging and causing any damage to the solar system. The current being generated by the solar panels and traveling to the battery is regulated with a solar charge controller.

Factors To Be Considered Before Buying The Best Solar Charge Controllers In India

1. Types Of Solar Charge Controllers:

The first most important factor that you must have some knowledge about before buying the best solar charge controller in India is the types of controllers available. 

2. Maximum Current:

You must check the maximum current rating of the solar charge controller before making a purchase. It tells a lot about the performance of the controller as well as its capability of handling high-load appliances. It indicates the maximum current that the device can deal with. Basic budget models can usually handle 10 or 20 amps of current, whereas the more high-end ones can handle 30 to 40 amps. 

3. Voltage Rating:

This is another crucial factor that you need to consider. The voltage rating does not affect the performance of the controller in any way but it ensures versatility and compatibility levels of the device. Almost all the solar charge controllers mentioned in this article are compatible with both 12-volt and 24-volt solar panel systems. 

4. Warranty:

Once installed, solar panels tend to last for decades. However, this is beneficial only when the other parts of the solar panel are just as reliable. To ensure that the solar system functions for a long time, check for the warranty offered by the solar charge controller company. Most of these devices come with a 1-year warranty but a few better ones have a 2-year warranty on them.

MPPT solar charge controllers have a higher power output compared to the PWM solar charge controllers. It can harvest an additional 11.1% of energy. Thus, MPPT is better than PWM. 

2. What capacity solar charge controller do I need?

This depends on the amount of energy that your solar panels produce. You require a solar charge controller that can handle this load efficiently. Thus, if the panels produce 480 watts of energy then you require a 20 amps solar charge controller. Typically, the amperage rating of controllers ranges from 1 to 60 amps. 

3. How many watts can a 20 amp solar charge controller handle?

A 20 amps solar charge controller can handle approximately 480 watts. 

4. What is the function of a solar charge controller?

A solar charge controller is essentially a protective guard that limits electrical energy flow from the solar panels to the battery. It prevents overcharging as well as undercharging. It also protects against excessive voltage flow. 


Solar charge controllers are a boon for all solar panel users because of the crucial protection to the solar battery. A lot of damage is possible without the controller regulating the flow of energy from the solar panels. Through this article, we have tried to provide you with adequate knowledge about the workings of a solar charge controller along with a list of the best solar charge controllers in India. We hope it benefits you in making the right decision. 

In recent years, heightened awareness about climate change has made countries shift from conventional, non-renewable sources of energy to non-conventional, renewable energy sources. In this scenario, solar energy is fast emerging as an alternative, particularly in equatorial and tropical Third World countries. Solar energy is a green and affordable alternative, and its use is central to the goal of achieving sustainable growth and development. 

In this article, we will focus on the main economic benefits of solar energy. We will also touch on some of the environmental benefits as well, because sustainable development entails that environmental benefits outrule economic benefits in the long run. 

Economic Benefits of Solar Energy

1. Lower energy bills

Traditional ways of saving on energy bills, such as switching to LED lighting, using natural ventilation instead of using an air conditioner, etc. can help bring down energy bills, but only up to a certain extent. At the end of the day, you will have to be completely dependent on your energy provider, and pay whatever the monthly charges are in accordance with your energy consumption. This is not the case with solar energy. Solar energy helps the consumer attain self sufficiency in meeting energy requirements, and drastically reduces one’s dependency on the discoms. If you install high capacity solar panels on your rooftop, you can power a large number of electrical appliances in your home or office. Although the initial investment on solar panels is high, in the long run, there is a high return on investment, as these panels can last for more than 25 years without requiring much maintenance.  

2. Net metering

Net metering is one of the most unique economic benefits that come with a solar PV system installed at your home or office. Net metering allows you to send the extra energy produced by the solar PV system back to the grid, and earn credits for it. During certain months in a year, when sunlight reception is maximum, the solar PV system might produce more energy than is required. If you have opted for net metering, you can send this extra energy back to the local grid of your area. The credits thus earned can be used to avail electricity during the other months, when demand for energy is higher than the supply by the solar PV system. Solar net metering also allows developers to set up rooftop solar plants at various locations and earn money out of it.  However, you need to ensure that your state has a net metering policy for you to avail net metering. 

3. Get rid of Time-of-Use (TOU) rates 

Time of use (TOU) rates can result in an increase in energy bills, as electricity consumed in peak hours, i.e. those times of the day when the demand for electricity is the highest, is charged more than the electricity consumed in normal hours. If you have a solar PV system installed at your place, you won’t be required to comply by the TOU rates of your electricity distribution company. This can lead to a lot of savings on your energy bills. 

4. State subsidies 

Transition to solar energy requires a lot of initial investment, as the installation requires solar panels, batteries, and wiring, among various other things. As a result, people are generally skeptical about making a transition to solar energy, as they do not have the money in the first place, and they are not sure about the return period on investment. However, to make things easier, a number of state governments, as well as the central government, have come up with policies to lower the burden of investment on the people by the means of subsidies on solar panels, easy loans, etc. Some Indian states offer up to 50 percent subsidy on solar panels. All of these measures are being taken to make people switch to renewable energy and reduce carbon emissions. 

5. Solar home value 

Many studies have shown that investing in solar energy can increase the value of your home by many times. Thus, if you are planning to sell your property in the future, it will be a good choice to buy and set up a solar PV system. Energy bills are expected to rise in the future, and solar power is the future. Hence, people are going to prefer buying a place that has a solar PV system.

6. Sunlight is free - Zero operational cost 

Conventional energy sources are dependent on natural resources, and with time, as these resources deplete and their prices go up, consumers will have to pay more in terms of their energy bills. The best thing about solar energy is that sunlight is free! Thus, apart from the initial investment that you would be making on installing a solar PV system, in the long run, you will effectively incur no cost at all for operation. Of course, there is maintenance cost involved, but that is insignificant when compared to the benefits. 

Environmental benefits of solar energy

In the previous section, we discussed the economic benefits of solar energy. As already stated, apart from the direct economic benefits that solar energy offers, there are endless environmental benefits associated with it, which are vital for sustainable growth and development. The following are some of the environmental benefits of solar energy:

1. Reducing greenhouse gas emissions 

Fossil fuels used in conventional energy sources are the major sources of greenhouse gasses. Solar energy, on the contrary, makes use of sunlight and is a non-polluting source of energy. Thus, it helps cut down on greenhouse gas emissions. 

2. Air pollution 

Studies show that some 6.4 million people die every year from illnesses related to air pollution. Every year, we hear news reports about the poor quality of air in cities across the world. As solar energy has zero carbon emissions, it can help with cutting down air pollution drastically, making this world a livable, breathable place. It can contribute to the healthy lives of individuals, and reduce medical bills. 

3. Social impact

Global warming has increased the incidences of forest fires, floods, droughts, and storms. It has led to rising sea levels, making people living on the coast vulnerable. In fact, global warming affects the poorest of the poor the most, destroying people’s livelihoods and devastating their lives. A transition to solar energy can help reduce global warming, and in this way, it can reap benefits for all sections of society. 

4. Job creation 

The solar energy sector is expanding with time, and a number of employment opportunities are becoming available to people as a result. Solar energy is, thus, responsible for job creation, which is very important for the unemployed youth in developing, low-income countries. 


In this article, thus, we talked about all the major economic and environmental benefits, which are associated with solar energy. As climate change has emerged as the overarching threat the human civilization faces today, switching to alternative, green sources of energy is becoming the need of the hour. If you are amongst the ones who are skeptical of making a transition to solar energy, we would advise you to go through this article thoroughly to find out about the immense economic benefits of solar energy

Net metering is an incentive that allows you to store the extra energy produced by your solar photovoltaic system in the grid system, in exchange for credits. The credits can be used to “take back” energy from the grid in situations when the solar PV system cannot produce sufficient energy due to factors like low sunlight.  It is a quite simple technique that helps bridge the differences between needing more energy at a moment and generating more than required at the other during any particular year. For instance, in India, most areas receive bright sunlight during the summer months, whereas the same areas receive a low income of sunlight during the winters. Net metering allows establishments with solar PV systems to store the extra energy produced during the summer months in the grid, and then “take back” energy from the grid when the cold winter comes along. With solar PV systems rising in popularity and increasing in scale, different state governments in India have come up with their own set of policies regarding net metering.

In this article, we will talk about everything that you need to know about net metering so that you have in-depth knowledge about the topic before making the transition to solar energy for your home or office. 

How does net metering work?

To use net metering facilities, the solar PV system needs to be connected to the utility grid via the main service panel of the consumer and the meter. The meter should be a bi-directional meter, as when more power is generated by the solar PV system than required, the excess power can be returned to the grid by reversing the meter from its normal direction. Since the meter works in both directions, one can get readings of both power purchased (when demand on-site is greater than the on-site power production) and power returned to the grid (when demand-on site is less than the generation on-site). The customer pays the “net” of both transactions. 

Why is net metering important?

Net metering offers a number of benefits to consumers, and is also good for the environment. By transmitting the excess power to the grid, energy wastage is prevented. The grid, similarly, receives power from a green, renewable energy source, apart from receiving energy from conventional power sources like thermal power plants. Besides, the consumer can save thousands of rupees on energy bills every year. Thus, net metering is a very good money saving choice, and it prompts people to switch to a solar PV system. It can result in an increase in the return on investment on a solar system. 

There is another advantage of net metering. Since your solar PV system is generating electricity near the point where it will be used, this process reduces the strain on the transmission and distribution infrastructure of the grid. It also minimizes energy loss which is associated with sending voltage to places far away from the power plant. Some studies, however, have claimed that net metering creates an unfair burden on non-solar customers. However, other studies involving cost-benefit analysis of net metering have found the opposite to be true. 

Can you make money net metering?

When you opt for net metering for your home or office, you only pay for the deficit power consumed, i.e. the difference between the power consumed from the grid and the solar power generated by the solar PV system of the home or office. As a result, there is a drastic reduction in the electricity bills, and it provides you with the opportunity to earn an income. Besides, these savings on energy bills from net metering add up with time, increasing your return on investment. Corporates, industrial establishments and educational research institutes can save a lot of money with the help of net metering after making a transition to a solar PV system. The money saved can be used to invest in other businesses in the case of corporate establishments and in the case of educational institutes, this money can be used for the development of educational infrastructure. Thus, net metering offers a great amount of impetus to the growth of an economy and the development of a society. 

Apart from the money you directly earn from net metering, switching to solar energy can have a high return on investment in the long run because the Government of India offers financial subsidies for solar panel systems, under certain conditions. The up-to-date data on cost and capital subsidy terms for rooftop solar PV systems can be checked on the website of the Ministry of New and Renewable Energy, Government of India. In addition, the Department of Financial Services has directed all the Public Sector Banks in India to encourage giving home loan/home improvement loans to those who want to install rooftop solar plants and to include the cost of the system in the home loan proposals. All of these are initiatives that can encourage net metering. Besides, the government also plans to introduce a ‘rent a roof’ policy under which the investors can rent/lease roofs from households and install a solar PV system to feed power to the grid. The responsibility of maintaining the system will be with the investor/developer. 

Challenges of net metering in India 

The following are some of the challenges of net metering in India:

1. Voltage fluctuation and imbalance in the voltage 

Since the energy generated by a solar PV system is dependent on the availability of sunlight, there can be drastic variations in power due to reasons like changes in weather conditions. As a result, there are rapid voltage fluctuations, which can lead to faults in the transmission network. In some cases, such fluctuations can overheat the power lines. Solar PV systems come with inverters, which are designed to regulate the voltage. Voltage fluctuations can arise because of the improper functioning of the inverter. If fluctuations move outside the specified values, the system should be designed to automatically disconnect itself from the grid. 

2. Electrical Disturbances 

Electrical disturbances, which produce harmonics, are generally caused by the presence of non-linear components in the solar PV system. They can lead to the overloading of equipment and metering errors. As such, the total harmonic disturbances produced by a solar PV system should not exceed 5 percent. Similarly, the individual and current harmonic disturbances should not exceed 3 percent and 8 percent respectively, so that the quality of power in the grid is not affected. 

3. Transmission of unwanted current in the grid

The power generated by the solar panels is DC current, whereas the one supplied to your house is AC current. The solar PV inverter converts DC current into AC current. However, there remains a possibility that the inverter passes unwanted DC current into the AC-driven network of the power grid. This can result in overheating of the transformers, damages, and power losses. 

4. Unintentional islanding

Unintentional islanding occurs when the solar PV system continues to supply power to the grid even when the grid power is off. This leads to safety issues for technicians, as a power line that is considered off may still be powered. 

5. Reverse power flow

PV penetration at high levels leads to reverse power flow. This happens in the case of a weak network, or when the consumption at the consumer’s end is lower than the power fed to the grid. This can lead to an increase in voltage, causing the electricity to change its direction and flow. As a result, there might be overheating in the transformer and transmission lines. 

6. Policy problems

Most states in India currently have their own net metering policy. However, net metering is still characterized by slow implementation and arbitrary constraints and limits. For instance, a number of states do not allow net metering for large off-takers of power (i.e. HT power consumers). Besides, in most states, there is a cap on the size of the solar plant that can be availed under net metering. 

Due to the poor implementation of net metering policy and business-unfriendly net metering rules, the rooftop solar sector in India is still underdeveloped. This is despite the fact that a number of industries in India have lots of idle spaces on roofs, which can be used for solar plants. 

Net metering policies in India 

At present, 18 out of the 29 Indian states have net metering policies. West Bengal was one of the first Indian states to have formulated a net metering policy, back in 2013. Most of the other states have come up with their own net metering policies in recent years. Some of these states, such as Karnataka, Uttar Pradesh, Haryana, Telangana, Gujarat, Andhra Pradesh, Assam and Jharkhand allow for both net and gross metering. Besides, most of the 18 states now allow for a 100 percent capacity with respect to sanctioned load for net metering. However, the limitations on transformer capacity vary, with the limitation being as high as 90 percent in the case of Tamil Nadu, and 20 percent in the case of Assam and Jammu and Kashmir. 

Most of the states which allow net metering follow a yearly cycle of compensation, with Telangana, Andhra Pradesh and Karnataka being the only exceptions. The billing period for settlement in most states is monthly. 


Net metering is an ingenious way of reducing the burden of energy bills. It is also an environmentally friendly solution, as it prevents the wastage of electricity by sending the excess electricity produced by the solar PV system to the grid. Besides, it encourages entrepreneurship in the rooftop solar energy sector. 

In this article, we covered each and every aspect of net metering. We answered many relevant questions, such as why net metering is important, can net metering enables us to make money, how net metering works, etc. Besides, we covered the challenges of net metering in India, and also discussed in detail the policies that different Indian states have with regards to net metering. We would advise you to go through this article thoroughly to understand what is solar Net Metering and how it works for home solar panels.

Factors To Consider Before Buying The Best 375-watt Solar Panel

1. Types Of 375-watt Solar Panels

The different types of 375-watt solar panels are based on two factors- the mounting type, and the technology used. 

a. Mounting Type- There are two ways in which solar panels are mounted or fixed to someplace. Thus, there are fixed solar panels and flexible solar panels. 

1. Fixed Solar Panels- The fixed solar panels are the conventional type of solar panels that have been available in the market for quite some time now. These solar panels are fixed on the rooftop into a corrosion-resistant aluminum frame. An EVA film and a TPT back sheet are used to design the solar panels. 

Fixed solar panels are used for multiple purposes on the utility, commercial, and residential scale and hence, they are commonly found in the market. You can install these solar panels in boats, small cabins, and trailers. 

2. Flexible Solar Panels- With a growth in the demand for portable appliances, the popularity of flexible solar panels became unparalleled. The best 375-watt solar panels are now mostly flexible so that they can be carried from one place to another easily. These solar panels have been designed to be compact and lightweight for this purpose. 

b. Technology

Solar panels across the country are designed based on two technologies- monocrystalline and polycrystalline. 375-watt solar panels are available based on either of these two technologies. 

1. Monocrystalline Solar Panels- These are the more superior-quality solar panels that are not only more efficient, and durable but also more expensive. It has an efficiency rate of 18-25% which is higher than that of polycrystalline solar panels. They have round edges and a dark black look which makes it easy to recognize them. 

As the name suggests, these solar panels are made using a single crystal seed that is turned into a solid crystal structure after placing the seed in molten silicon. A single solar cell is then formed by integrating the sliced silicon wafers. Brands usually offer a 25-year warranty on the panels and they tend to last even longer than this in most cases. 

2. Polycrystalline Solar Panels- If you are looking for a low-cost option while buying solar panels, those made using polycrystalline technology are the ideal ones. The low price does not mean any compromise on quality. Premium-quality materials are used to make polycrystalline solar panels as well. 

However, these solar panels boast a 17-20% efficiency and last for a shorter period as well. Multiple crystals are used to make them and you can easily recognize a polycrystalline solar panel by its blue color. They usually have a lifespan of 25-28 years which is slightly less than that of the monocrystalline solar panels. 

2. Weight

Another crucial factor that must be taken into consideration before buying the best 375-watt solar panel is the weight of the panel. This is important because it directly dictates how portable or heavy the solar panel is. Look for a lightweight and ultra-thin solar panel if you wish to move around the panel frequently and also if the rooftop space is limited.  

Flexible solar panels weigh less than 2 kgs and hence, it’s therefore well suited for being moved around. The less weight of these panels is also advantageous as when there are storms or heavy snowfall as it reduces the chance of any major damage. It also reduces the pressure on the rooftop. 

3. Dimensions

All 375-watt solar panels are designed using the same measurements with slight changes here and there. These dimensions are decided based on the power that the solar panel generates. 375-watt solar panels are medium-sized and the size is ideal for both residential rooftops as well as commercial buildings. However, if you wish to power many appliances at the same time, you will have to connect many such 375-watt solar panels to generate sufficient power. 

4. Price

Before buying the best 375-watt solar panel, you must make sure that you are aware of the price and that it is at par with your budget. Begin by deciding on a set budget for your purchase and try to stay within it. However, do not compromise on the quality of the solar panel just to meet your budget. A cheaper model might look appealing but make sure that it has a 25-year warranty and the service is provided by the brand. 

5. Efficiency

Efficiency is a factor in which you cannot compromise no matter what. Space is usually an issue, especially when you are trying to install it in a residential area. All this considered, every inch of the space available counts and must aid in the generation of power. Moreover, the power generated by a particular module decreases over time, and hence, choosing a low-efficiency solar panel might not be a great idea. 

Look for a solar panel with a high-efficiency that also fits into your budget. This way you can ensure that there is enough electricity for all the appliances in your home or office. 

How To Install a 375-watt Solar Panel?

1. Organize

The most important and the first step in installing a 375-watt solar panel is to organize the space where the modules will be installed. You must first take a close look at the space where the panels will be set up; be it the rooftop of your home or any commercial building. This will help you envision how you might place the solar panels. 

Organize the space before installation or during installation by making sketches and plans so that the solar panels are well-distributed. 

2. Install The Mounting Brackets

The next step in installing the best 375-watt solar panel is the installation of the mounting brackets. It is better to install the mounting brackets while you are still on the ground and before you go to the rooftop. This way you can save on any additional labor expenses. 

3. Install Other Components

This is an important step in the installation process. The other components of a solar system are the charge controller and the battery. These need to be set up in the RV first. Once that has been accomplished, select the shortest path to connect the wires. A longer path will increase the chances of voltage drops as well as increase the power losses. 

4. Drilling and Mounting

Once all the steps have been taken care of, it's time to start with the real work of connecting all the wires and placing the solar panels that were planned. The AWG wires (12-10 AWG) need to be passed through holes that you need to drill. DC breakers must be installed before this and fuses must be installed between the charge controller and the batteries. 

A waterproof cable entry plate needs to be installed on the rooftop and this will be connected to the series or the parallel connection between the solar panels. Next, drill four holes that will hold the modules to the roof and then install each of the panels according to the plan. Bolts and screws will help get this done.

The ever-growing popularity of solar energy is great when it comes to environmental sustainability. Our collective future hangs in the balance now more than ever and it is high time that harnessing renewable energy is realized to the best possible extent. Solar energy as a resource can be reliably used to fulfill our power requirements and more and more people have put their faith in it and are now reaping the benefits. However, the joy of using solar energy is two-fold. Not only does it let you manage your energy bills better, it also helps you reduce your carbon footprint.

Ever since it was discovered that solar energy could be stored and collected, the energy source has seen rapid growth in various parts of the world. We might even entertain the possibility that someday, all conventional sources of energy would eventually be replaced with solar and renewable energy. In this article today we will try and assess the environmental impact of solar power. We will speak about different ways in which solar energy is better for the natural environment as compared to the traditional conventional sources of energy. Apart from this, we will also discuss some of the costs and negative trade-offs that are associated with potentially higher levels of solar energy usage. 

The potential environmental impact of solar energy usage on a large scale can be divided into various subcategories such as land use impacts, ecological impacts, impacts to water, air and soil as well as its impact on society and economy. It's also important to mention that these impact assessments can vary depending upon the types of technology used by different solar energy systems. 

Ecological impacts including land usage 

Land is a very important factor if we are to produce large-scale solar energy that can be a genuine replacement for electricity. Such a solar energy system would require a lot of land for production as well as the collection of energy. As a result of this, there can be genuine ecological fallouts with regard to the ecological balance in different areas. The effect on flora and fauna could also be significant and these factors should be thought of prior to establishing a massive elaborate solar energy grid that can fulfill the needs of numerous households in a particular area. Special attention should be paid to the wilderness or recreational zones or parks while setting up solar energy grids. 

Another aspect that should be carefully considered is that the local ecological balance could also get altered as a result of activities such as exploration, extraction, manufacturing, and disposal of manufacturing and settlement processes. This could lead to significantly high energy footprints. Effective evaluation should be undertaken prior to planning procedures for the solar energy grid. There might be areas where the damage can be mitigated through careful and dedicated usage of the right inputs, time, and effort. However, there might also be other areas where the balance is delicate that once it is disturbed, it can never be restored.

Impact on Soil 

Any moderate to large scale construction of solar energy grids require a great deal of cleaning and grading of the soil. This results in the compaction of soil over time and also leads to alteration of traditional natural drainage channels which could cause issues related to the flow of water from local streams and water bodies. With higher levels of construction comes a higher risk of soil erosion which has a number of different adverse consequences for the region and its biodiversity. 

Impact on Water 

Often, large-scale solar energy projects require central tower systems. Each of these towers needs to be maintained and they consume a lot of water in order to remain cool. This is a serious concern in arid settings and should be adequately investigated before any major solar project. Apart from that, keep in mind that higher water demand is a strain on the ecological balance in any environment.

 Along with this, there are also factors such as chemical spillages which need to be considered. Chemical spillages often result in groundwater contamination that could take years to reverse and this could create major problems for not only the local human population but also the flora and fauna. 

Impact on Air 

Any kind of large-scale industrial facility will always cause certain environmental issues for the air in and around the area, including solar energy installations. Hazards to air quality can be because of different reasons and adequate safeguards should be put in place to combat these issues. For instance, one of the biggest issues surrounding solar installations involves the release of pathogens that are carried by the soil. This eventually results in increased levels of suspended particulate matter and this could also have an effect on contamination of reservoirs. 

Heavy Metal Contamination 

A lot of people have reported on the adverse effects of contamination as a result of the residue and excesses of heavy metals used in solar power installation areas. Some heavy metals pose contamination risks to the various biological and ecological balance in open areas. 

Metals such as Cadmium Telluride are notorious for causing minor to significant damages to ecological diversity. It is important to mention, however, that similar contamination occurs on a much larger scale in the case of coal and other industrial power plants which are engaged in manufacturing traditional metals and energy sources. According to some estimates, coal plant installations cause up to 300 times more pollution as compared to solar power installations. 

Other impacts 

Besides the ones we have already mentioned, solar power installations could also have other social and economic impacts. Things such as the construction of the facility would result in the creation of jobs of various kinds and this could bring positive change. 

Apart from the income drawn as wages and salaries, there would also be a requirement for specialized services and maintenance work for the construction and daily operations of the project. 

. The construction of large-scale facilities creates a demand for migration of workers to the specified area and this affects things such as housing, public expenditures as well local government involvement. 

Recycling Solar Panels 

At this point in time, solar panels do not have a great deal of recyclability. This is because there aren’t enough locations to carry out the recycling and it's not economically viable to recycle panels. . 

This is rather unfortunate as solar panels often contain a lot of precious metals such as silver, tellurium, and indium. All of these metals suffer from varying degrees of scarcity and there is a lot of scope to recycle them for future use. There is a lack of awareness when it comes to the recycling potential of solar panels and this needs to change. 


In this article today we tried to give you a comprehensive picture of the environmental impact of solar panel installations. We started off with a brief intro where we discussed the ever-growing popularity of solar panels and the numerous benefits it provides. Then we moved on to detailed explanations about the different kinds of impacts on the natural environment that could occur..  We advocate for increased recycling as the way forward to tackle these detrimental impacts and we hope you found this information useful. Until next time!

Alongside the type of solar panels you buy, their placement and direction is equally important. The panels can absorb the maximum energy when the sun’s rays hit them perpendicularly. You can ensure that the solar panels generate a sufficient amount of power when they face the right direction and have the correct tilt so that they receive maximum sunlight for a long period of time. 

Energy production  significantly increases in a few cases with the help of solar tracking systems that guide the solar arrays to follow the sun. In this article, we will discuss some important topics related to the direction of solar panels, the angle of their tilt, and so on. We hope that after reading it you will be able to reconfigure your solar panels to maximize energy production. 

What Direction Should I Point My Solar Panels?

The direction that your solar panels face depends entirely on your geographic location; that is, whether you live in the northern or southern hemisphere of this world. The general rule of thumb when it comes to setting up solar panels for those living in the northern hemisphere is that the panels must face true south and in the southern hemisphere, they must face true north. These directions are ideal because the solar panels can receive direct sunlight throughout the day only in this manner. 

You must, however, know the difference between magnetic south and true south to avoid any confusion. Magnetic south is the direction that the compass points towards and that is the Earth’s south magnetic pole. Whereas, the solar panels need to face the solar or geographic south, which is the direction of the South Pole. The same is the case with magnetic north and true north. 

The direction might vary as per the usage of the solar panels. In certain cases, it might be beneficial to slightly rotate the panels away from the south direction and more towards the south-west. While directly facing the south might help the panels collect more energy, rotating it away might help in generating maximum power when it is required. If you use your solar-powered appliances more frequently in the evening, for example,  and if the panels face the setting sun, they can produce more energy for this time of the day. 

It becomes ideal to make the panels face east when solar collectors are being used to heat and light up your home. Sunlight is needed the most if you wish to warm the house for the day. 

Can Solar Panels Face East Or West?

Ideally, solar panels generate maximum energy when they are south facing as compared to any other direction. However, the solar panels on your terrace may face the east or west direction. These panels produce 15% less energy on average when compared to south-facing solar panels. Even if the efficiency of the solar panels is lower when they are west or south-west facing, they will be more economical as the time-of-use billing will be less. 

The time-of-use billing is at its peak during the afternoon and for those households that do not require power throughout the day, west-facing solar panels are perfect. This way you can have solar panels installed on the rooftop and still save a lot of money. 

East-facing solar panels are not that uncommon either, even though they generate only 80% of energy. However, it is crucial to have net-metering for east-facing solar setups. This means that you are charged with the electricity bills as per your net electricity usage and this will help you save money.

Why Should Solar Panels Face North?

Solar panels should face north when they have been placed anywhere in the southern hemisphere which includes places like Australia, South America, or some Asian islands. It will receive maximum sunlight when facing north and this will culminate in a lot of energy production for all the appliances in your household. However, north-facing solar panels are ideal only when there are no obstructions on the northern side like buildings or trees. 

North-facing solar panels tend to be best suited for people or families that stay home throughout the day. Since they are home for so long, the use of appliances like pool filters, washing machines, clothes dryers, etc. is also more. Solar panels facing the north direction yield more energy and hence, they are ideal for such households. In many cases, it is possible to have the panels face different directions. 

While some might face north, others can face west so that the effect is somewhat like that of the north-west facing panels. This generates the least energy in the morning and the maximum energy in the middle of the day and the afternoon. This is a good thing if you wish to save money on your electricity bills. 

What Is Solar Panel Tilt Angle?

The solar panel tilt angle is yet another important factor that needs to be considered before you buy solar panels for your rooftop. You must have adequate knowledge about this to be able to assist the solar panels to generate the maximum energy for your home. The tilt or verticle angle of the solar panels. should directly face the sun  for ideal absorption of sunlight 

You must angle your solar panels depending on the latitudes of your location to produce maximum energy. For example, if the latitude of a particular place is 50 degrees then the optimal tilt angle should also be 50 degrees. The closer the solar panel gets to the equator, the more vertical it must be. 

They must tilt towards the equator if they are closer to the poles.. Certain climatic and environmental factors also influence the tilt angle of the solar panels. In places prone to heavy snowfall, the sun’s rays can be easily obstructed or even blocked with low tilted solar panels not getting much light. This leads to a great deal of energy loss in places like Canada and the like. Places prone to dirt and debris can also have a bad effect on low-tilted solar panels. 

What Is The Correct Angle For Solar Panels?

The sole purpose of the correct tilt angle for solar panels is to maximize the production of energy so that all the appliances in your home can depend on solar energy. It can be quite tricky to figure out what is the correct angle for solar panels because of the changing position of the sun throughout the day. In an ideal situation, you would be able to change the tilt-angle of the solar panels to suit the direction of the sunlight but that might not always be possible. Therefore, you must place it at an optimal angle. 

A steep angle of 60 degrees tilt is considered to be the best option to get the most out of your solar panels. During the springtime, the best tilt-angle is 45 degrees and once summer comes, you might want to have a low-tilt angle for the solar panels; preferably 20 degrees. 

How Do You Determine The Best Angle For Solar Panels?

You must know how to calculate the correct angle for solar panels and articles like this one can provide helpful guidelines on how to do the same. Solar panel angle calculators are beneficial in these cases, but you can also do the calculations on your own. Calculating the tilt angle during summers is quite different than calculating this angle during the winters. Two main methods are used for such calculations. 

One way of calculating the correct angle for solar panels is by subtracting 15 degrees from the latitude of the solar system. This is for summer days. You must add 15 degrees to the latitude for the winter days. This method has been criticized for not being very reliable. The second method for doing this calculation is by multiplying 0.9 to the latitude of the place and then subtract 23.5 degrees from the result

This calculation is once again for the summer season. For the winter season, repeat all the steps and then add 29 degrees to the result

What Are The Other Factors That Affect Solar Panel Angle?

There are a few other factors that affect the solar panel tilt-angle that you must take into consideration before purchasing a solar system. 

  1. Design Of The Roof:

Most people decide to invest in solar panels and install them on the roof because they guarantee an enhanced exposure to the sun without any obstruction. Most roofs have an inclination of 30 to 40 degrees which ensures that the panels get maximum exposure to sunlight. However, in many cases, if the inclination is bigger, it becomes difficult to achieve the ideal angle for the panels. 

In certain other cases, the optimal angle might be lower than the roof angle. The best thing to do in this case is to install the panels flat on the roof. You might also get a low-angle roof made but that will require a lot of money as well as time. A racking system can be built to hold the solar panels the right way when the roof has a small inclination. Racking systems are mandatory for flat roofs. 

Only by following these specific instructions and guidelines, you can achieve the correct tilt-angle and direction for the solar panels. 

  1. Solar Panels Direction:

We have already spoken a great deal about the direction of solar panels. This is the most crucial aspect of setting up a solar system since many other factors such as the tilt-angle, the power output, the durability of the panels will all depend on it. 

Frequently Asked Questions

  1. Can solar panels face different directions?

Yes, solar panels can face different directions if they cannot face the ideal direction, that is the true north for the southern hemisphere and the true south for the northern hemisphere. You can make the solar panels face both north and west directions if needed. You can even have the solar panels face more than two directions if required. 

  1. How does the angle of a solar panel affect the output?

The angle of a solar panel can greatly affect the output that it yields. Based on the position of the sun and your geographical location, adjust the tilt angle of the panel. The corrector the ideal angle will help produce maximum energy. 

  1. Can solar panels be laid flat?

Solar panels can work quite well on flat roofs as well. Most commercial buildings have flat roofs and can accommodate the flat roof solar systems quite well. You can use them in domestic buildings as well. 

  1. What is the solar hour angle?

The solar hour angle is the angle of the sun in relation to the solar panels at a particular hour. For example, at 11.30 am local apparent time, the hour angle is -22.5 degrees. 


A large section of the population is gradually shifting to solar energy not only to save the environment but also some money. For first-time buyers, understanding the workings and various aspects of a solar system can be quite challenging. Hence, we have gathered important information on the two most basic components of solar panels- their angle and direction. Hope the article is useful!

Factors to look for while buying a solar panel

1. Weight

The weight of the solar panel impacts its portability. If you are planning to install a panel on the rooftop of your house, it is easier to carry the panel if it is lightweight. Besides, weight is an important factor to consider as well because certain roofs  are designed to withstand weights only up to a certain level. Additional weight can pose a danger to the structural integrity of your building. This is particularly important to consider if you live in an area, which frequently experiences hail storms and snowfall. 

2. Dimensions

The dimensions of a solar panel are usually directly proportional to their output. However, this might not always be the case. A number of good quality and expensive solar panels can fit in a smaller space when compared to low-budget solar panels with the same rating. Before buying a solar panel, take proper measurements of the space where you are going to install the panel and make your purchase in accordance with the space available.

3. Price

As with any other product, price is an important factor to consider while buying a solar panel. There are a number of affordable, low budget solar panels available in the market, which the consumer might find desirable. However, not all these panels boast of a good quality. Since buying a solar panel is a huge  investment, you must be careful while choosing one. Go for a panel which should last for at least 25 years. It is always good to buy products offered by trusted brands, some of which have been listed in our reviews of the best 100W solar panels in India

4. Efficiency

It is important to keep in mind that due to solar cell degeneration, the power generated by a solar panel reduces over time. Therefore, choosing a product which features a low efficiency is not a wise investment decision to make. Choose a solar panel with the highest possible efficiency, even if it requires you to make slight adjustments in your budget. In this way, you can make sure that you will have enough power for your appliances in the long run. 

5. Fixed Solar Panels and Flexible Solar Panels

Traditionally solar panels have been fixed units, with an EVA film and a TPT back sheet cover, fixed into a corrosion-resistant aluminium frame. In fact, fixed solar panels are the most common in the market. They are used for both commercial and residential purposes. Low output, fixed, mounted solar panels are generally used for boats, RVs and trailers with flat rooftops. 

Flexible solar panels are a new introduction in the solar market, and are quickly becoming popular. They can bend up to 30 degrees and are therefore considered the best solution for curved surfaces in trailers and yachts. Another advantage of these panels is that they are lightweight and ultra thin. They are also a great choice for  campers, as they are easy to install. However, a drawback found in flexible solar panels is that they are available only in 50 W and 100 W options. 

6. Monocrystalline and Polycrystalline Solar Panels

Monocrystalline solar panels offer a high degree of module efficiency (18 to 25 percent). Their distinct homogenous, dark black look and rounded edges makes them easily recognizable. As the name suggests, monocrystalline panels are made from a single crystal. The single crystal seed is placed in molten silicon and is left until a solid crystal structure, known as a cylindrical ingot is formed. In the later stage, the crystal is cut into silicon wafers, which are then integrated into a solar cell. Due to their manufacturing process, monocrystalline solar panels tend to have longer lifespans, ranging between 25 to 35 years. Thus, one gets a high return on investment on monocrystalline solar panels. 

Polycrystalline solar panels are a lower-cost alternative to monocrystalline panels. While they came to the market before monocrystalline panels, they have a lower degree of efficiency, with module efficiency ranging between 17 and 20 percent. Understandably, polycrystalline panels differ in terms of manufacturing process from the monocrystalline panels. They are made from multiple crystals cut in square ingots, offering a heterogeneous blue look. They tend to have a shorter lifespan, too, as they can last between 25 to 30 years. 

Frequently Asked Questions 

Q1. How fast will a 100w solar panel charge the battery?

There are a number of factors which influence the total time required by a solar panel to charge a battery. The size, type, and state of the battery are some of these factors.
Considering that you are using a 50 Ah battery, a 100 W solar panel will usually take 9 to 10 hours to charge the battery, when completely drained. This is because a 100 W, 12 V solar panel produce around 5.5 amp hours of energy per hour. 

However, if your battery is old or the cables are damaged, it will take a much longer time for the solar panel to charge it. Besides, weather conditions, and factors like position of the sun, etc. can also impact charging time.

Charging cycles are invariably slower on cloudy days. The best 100 W solar panels in India which we have reviewed in this article are of good quality, and therefore, they shall offer faster rates of charging under bright lighting conditions. 

Q2. Can a 100 watt solar panel run a refrigerator?

No. A single 100 W solar panel cannot run a regular refrigerator. Firstly, for running a refrigerator, you need to have a battery which is rated at around 10 times the running wattage of the refrigerator. This is necessary to ensure reliable functioning.

This means that even if you are using a small fridge of 130 watts, you need to have an inverter with a rating of 1500 watt. A 100 watt solar panel will take days to charge an inverter of that capacity. Therefore, it is impossible for a 100 W solar panel to run a refrigerator. 

Q3. Can a 100 watt solar panel power a TV?

Unlike a refrigerator, an LED or an LCD TV does not consume a lot of power. Therefore, if you have a small LED or LCD TV, your 100 W solar panel can keep it running for around 5 hours without any difficulty.


Solar panels are becoming more and more popular, reducing humankind’s dependency on pollution causing  fossil fuels.. Today, solar panels are being used in a variety of spaces and are being used to power homes, offices and utilities. As such, they are widely available in the market. However, choosing a solar panel can be a bit tricky, as there are a number of things to be aware of before making any such purchase.

Therefore, in this article, we offered you a buyers’ guide for 100 W solar panels in India. We reviewed some of the best 100 W solar panels in India, and listed down all the important factors which one must be aware of before buying a solar panel. We also answered some of the frequently asked questions related to thesesolar panels. Go through this article thoroughly and buy a solar panel that best suits your requirements. 

Solar panels are an ingenious way of producing electricity without harming the environment in the form of carbon emissions. Photovoltaic solar systems have been in existence for long and a question that many customers, both the pre-existing users and those planning to switch to solar systems, ask is ‘how long do solar panels last on average'. In this article, we are going to elaborately answer all the concerns related to the longevity of solar panels. We will also talk about the maintenance and warranties of the solar panels so that you can have a good idea before making a transition to a solar PV system for your home or office. 

Solar Panel’s Longevity 

According to research conducted in 2012 by the National Renewable Energy Laboratory of Colorado, US, the output of a solar panel reduces by 0.8 percent on average, every year. This degradation rate translates into a 20 percent reduction in total power output generated in the 25th year. In other words, after 25 years, you will obtain an energy output of 80 percent as compared to the output in the first year of installation. However, it is important to note that this study was based on the analysis of older solar panels. Over the years, improvements in technology have reduced this degradation rate, and this translates into higher output, even after many decades of usage. In addition, the degradation rate depends on a number of other things, such as the brand of the panel, as well as the type of panel used. In sum, we can say that even after many years, solar panels are going to work just fine, retaining most of their initial output produced. 

Why do solar panels degrade?

There are two main factors responsible for the degradation of solar panels: a) the type of the panel b) the impact of natural forces like weather and climatic conditions. Speaking of the type of solar panels, crystalline panels offer a greater degree of resistance against extreme weather conditions, and they can withstand heat and cold for more than two decades. Film panels, on the other hand, are more sensitive to changes in weather conditions and the process of degradation starts quite faster. 

The location of your home and office and the underlying weather and climatic conditions of the area are other important factor responsible for the degradation of solar panels. Areas receiving strong wind blows, hailstorms, heavy snow loads, and exhausting heat and humidity tend to have a significant impact on the longevity of solar panels. On the other hand, solar panels installed in areas with favorable climatic conditions will degrade at a much slower pace.

Can you really increase the lifespan of solar panels? 

Solar panels require regular check-ups by professionals from time to time. Proper maintenance can keep your solar PV system in good condition for a long period of time. Make sure that the installer thoroughly examines all the panels of the solar PV system each year. In this way, you can avoid some serious defects, which show up with solar systems. However, make sure that you allow only a certified solar PV system installer to carry out inspection and repair work, and not to attempt doing it yourself. Solar panels are complicated devices, and you can make things worse by trying to fix things on your own. It can also lead to the annulment of warranty on your solar panel. Regular maintenance work will reveal any potential problems with the panel, such as exposed wires or loose racking. 

Apart from the solar panel, there are other components in a solar PV system that needs attention. They are important for the healthy functioning of the system. The standard inverter battery, for example, has a lifespan of 15 years and needs to be replaced at some point during the lifetime of your solar PV system while the microinverters last for a longer period and require to be changed only once in 25 years. 

Since wind and adverse weather conditions can affect the longevity of the panel, make sure that you choose the location wisely before installing. For example, mount them tightly and securely to the roof, so that the solar panels are not affected by strong winds. Similarly, ensure that there is no object standing close to the panel, which deflects the sunlight. Besides, make sure that the solar panels are clean, without dust piling on top of them. 


Warranty is an important factor to consider while buying any appliance or device, and solar panels are no exception. Besides, solar panels involve a huge investment and therefore, it is always smart to protect yourself against incurring extra costs, in the long run. Usually, solar panel manufacturers offer a warranty period of 25 years, which means that the system will generate an acceptable amount of energy during this entire period, without much degradation. Besides the production warranty, manufacturers also tend to offer 12 to 15 years of equipment warranties on solar panels. Equipment warranties cover defects, as well as environmental damages to certain parts of the solar PV module. 

What happens when a solar panel becomes completely dysfunctional? 

Solar PV modules are a relatively new technology, and solar panels have become popular only in the last two decades. Most of the solar panels that are currently installed are a decade and a half old, and therefore, not much data is available to understand the condition of solar panels after 25-30 years. However, there are examples where solar panels have outperformed their factory specifications and their specified lifespans, offering longer periods of uninterrupted usage. 

Solar panels are an environmentally friendly alternative, as they minimize carbon emissions. Besides, there is no wastage associated with them, as once installed, the solar PV system continues to work for decades. They just need to be checked and cleaned at regular intervals. 

Proper disposal of a solar panel is something worth considering, since generating waste is not desirable. Once you decide to replace your old panel with a new one, you must look for companies that deal with the recycling of solar panels. At present, the solar panel recycling industry is at its nascent stage, because of the obvious reason that most solar panels are relatively new. However, this industry is going to expand and develop in the future, and we hope that disposing of old solar panels will become easier and handier. 

How often do you have to replace solar panels?

If not physically damaged, a solar panel can easily last for 35 to 40 years. A replacement is required only when the power output drops below 80 percent. As already stated, most solar panels can effectively maintain an efficiency level of over 80 percent, for about 25 years. The newer panels, on the other hand, have a degradation rate of about 0.5 percent per year, which means that it requires more than 35 years for the efficiency to drop below 80 percent. Physical damage is unlikely to happen to a solar panel because it does not have any moving parts. 

How do I know if my solar panels are going bad?

There are a number of ways in which you can figure out whether your solar panel is undergoing deterioration. Following are some of them: 

Voltage and Current Output

You can measure the output generated by the solar panel and compare it with its nominal rating and specifications. Make sure that you measure the output only at noon on a bright, sunny day, for optimal results. Some solar installations come with current and voltage displays, through which you can monitor their performance. However, if your solar PV system has no such display, you can use a multimeter to measure the output. If the readings are more than 20 percent below the nominal rating, then we can say that the panel might be wearing out. 

Physical Deterioration

Physical deterioration is something that is visible. Weather and climatic conditions are the most important reasons for physical deterioration of solar panels. For instance, hailstorms can cause cracks on the panels. Temperature differences can also result in cracks in the enclosure. A careful physical inspection can reveal any such physical deterioration. Besides, do not forget to clean the panel regularly in order to get rid of dirt and dust.  


As already noted, the usual lifetime of a solar panel ranges between 30 to 40 years. If your solar panel is more than 25 years, with a significant reduction in performance then, it is time to change your panel. 

Related Components

Auxiliary components connected to the solar panel can also lead to a decrease in output. Each of these components themselves have a specific lifetime, beyond which it needs to be changed for the healthy functioning of the solar PV system.


 In this article, we discussed in length the longevity of solar panels. We not only answered how long solar panels last on average but also many other related questions such as warranties, physical deterioration, maintenance, etc. Go through this article to resolve any queries regarding the longevity of solar panels.

This could definitely be one of the best if not the best residential solar systems that you can invest in. 

Factors to consider while buying the best solar system for home 

1. Usage 

The capacity of solar panels to generate power and run your appliances smoothly is largely dependent on your overall expected power consumption. Whether you are running traditional appliances or involved in any kind of commercial projects, the right kind of solar panel setup really helps you rescue your dependency on traditional power sources. You can use the right solar setup to do a number of things such as heat water or  charge your batteries. 

In order to build your setup effectively and narrow down your list of options, it is important for you to have a good understanding of how to use the solar setup. You also have the option of essentially selling energy by exporting the excess power to your local grid and thereby rescue your electricity bills. If this is something that you are considering, make sure to get a setup that can support this kind of usage. 

2. Versatility 

The versatility of solar panels is arguably one of the most important elements to think about while shifting to renewable solar power.. Not only do they run all of your daily household appliances, but they can also perform functions that you were probably not even aware of. They can easily perform tasks which require low to medium power such as cooking, creating indoor lighting etc. 

The versatility requirement of solar panels also depends on the location where you are planning to install it. Whether you choose to mount it on your roof or at the top of an RV or wood cabin, you have the option of setting it up in a number of different places according to your convenience. Solar panels can provide energy where required without having to be explicitly close to the populated palace or grid connectors. If you are looking to mount your solar panels on an uneven surface, we would recommend flexible and lightweight panels for best results. 

3. Technology 

There are three main technologies used by solar panels and we will discuss each of them in brief in this secretion. First, you have the photovoltaic panels which are also called PV panels. These panels directly transform sunlight into energy that can be used by household appliances. Next, we have CSP that concentrates solar power by using the energy from the sun to trigger the functioning of electric turbines. Your solar panel may also include SHC or solar heating and cooling systems. 

The panels themselves are often made out of silicon solar cells which are generally used as a part of a solar roof construction setup or while setting up a large-scale ground utility system. Next, we have thin-film solar panels which are useful in their own regard. They are highly flexible and lightweight which makes them ideal to use as a portable appliance.

The next type is known as III-V solar cells which are the most expensive option. These panels are able to transform sunlight into usable energy in a more efficient manner. Finally, at last, we have the next-generation solar cells (NREL) which are constructed using hybrid organic-inorganic materials that are easy to manufacture.  These are also very affordable for the same reasons. 

4. Efficiency 

The efficiency of a solar panel setup refers to the amount of energy from the sun that is generated into usable electricity by each panel. There are different factors that can influence the overall efficiency of your solar power setup. Various factors such as the reflectance efficiency and thermodynamic efficiency, shade from nearby objects and dust or dirt can also affect your overall efficiency rating. Make sure to study these points in detail and also ensure that they do not render your overall system  unviable at any time down the line. 

However, make sure to note that efficiency is not everything in a solar setup.. Even if your panels are not the most efficient, you can fulfil your requirement if you have for instance a large roof covered with an adequate number of panels that receive a lot of sunlight. The average efficiency of a solar panel ranges from anywhere between 15 to 18 percent and could go up to around 23 percent. 

Frequently Asked Questions 

Q1. What are the financial benefits of using solar energy? 

Solar energy gives you the opportunity to cut down your electricity bills in varying degrees depending upon your levels of electricity usage. Given the utility rates and solar policies in your state, you can enjoy significant savings from setting up a solar energy system in the long run. This also means that you can reduce costs in the future even if the costs of electricity rise.

Q2. What are the different financing options available to purchase a solar power setup?

When we talk about financing your solar setup, you have three different options at your disposal which are viable. The first is to sing a solar power purchase agreement or a solar lease. The second is to take a bank loan to purchase the system and pay it off overtime. However, ensure you calculate the interest beforehand. The last option is, of course, to pay for the system up front.

This is where our article comes to an end and We wish you the best in your journey.

Bifacial solar panels can generate power from both sides of the panel, and thus, increase the total energy generated by a solar module. Traditional solar panels, on the other hand, are monofacial, as they come with opaque backsheets, which allows solar energy to be trapped only by one side. As a consequence, bifacial panels are fast becoming popular for both home and office installations. These panels also offer a greater degree of durability because both sides are UV resistant. Moreover, frameless bifacial solar modules reduce concerns related to potential-induced degradation (PID). 

Installing bifacial solar panels on a highly reflective surface, such as a white TPO roof, or on a ground with light colored stones can help increase energy generation up to 30 percent, in comparison to monofacial panels. In addition, since more power can be generated, bifacial panels also lead to a reduction in Balance of Systems (BOS) costs. 

Bifacial solar panels are available in various designs. The following are some of the design variants of bifacial modules:

It is important to note that there are frameless, dual glass modules, which expose the backside of the cells, but are not bifacial panels in the true sense of the term. What distinguishes true bifacial panels from these frameless, dual glass modules panels is that the former have contacts/bust bars on both the back and front sides of their cells. 

How do bifacial solar panels work?

The top solar cells of a bifacial solar panel work along the same principle as any conventional, monofacial panel. They face the sun directly, and capture sun rays directly by absorbing only certain wavelengths. IThe bottom solar cells, however,  have a slightly different operating principle. They absorb the light that is reflected off the ground surface. This light is known as albedo light. Since white or light colours offer a better reflection than dark colours, it is advisable that you should paint the surface of the roof white or silver. A concrete driveway under the panels can also be a good option, and is capable of producing a similar effect. Some studies have shown that white surfaces reflect more than 80 percent of albedo light (By comparison, grass only reflects 23 percent of albedo light). 

Besides, the use of superior silicon in monocrystalline solar cells is preferred, as it optimizes the operation of the underside cells. Monofacial solar panel systems are placed in racks parallel to the ground surface for optimum performance, because  that way, the maximum amount of sunlight is captured. However, bifacial panels work differently, and thus, they must be angled correctly on the roof or ground at varying degrees for optimum energy production.

Are bifacial solar panels worth it?

Bifacial solar panels offer a great deal of advantages over the monofacial solar panels. Following are some of the advantages and disadvantages of bifacial solar panels:

In recent times, the contribution of solar energy has grown significantly. Solar energy has emerged as one of the most popular non-conventional sources of energy. The most common way solar energy is harnessed is through the use of solar panels. Solar panels are the most important component of any solar system. This article tells you about the materials used for making solar panels, answer some frequently asked questions regarding their manufacturing process and their impact on the environment. 

Materials used for making solar panels 

The following are the components of a solar panel:

Silicon - Solar Cells and Wafers

The most important component of any solar panel is  the solar cell. Solar cells are made of 99.99 percent pure silicon crystals. Silicon is the most important raw material used in solar panels. These silicon crystals are derived from one of the most abundant materials on earth which is - sand. It requires a complex purification process to convert sand into pure silicon crystals. This process requires sand to be mixed with carbon and subjected to temperatures upto 2000 degree celsius. With this process, the raw silicon gets converted into a gaseous silicon compound form. This is later  mixed with hydrogen to obtain a highly purified polycrystalline silicon. The  silicon ingots, thus obtained, are reshaped and turned into very thin slices of silicon, which are known as silicon wafers. This is  the heart of a photovoltaic cell. 


A solar panel consists of several layers. There is a layer of solar cells, which are connected in series through copper strips. Apart from the solar cells, there is a layer of EVA (Ethylene vinyl acetate) sheeting. EVA is a thermoplastic polymer with  good radiation transmission. Moreover, it enjoys a low degradability to sunlight. Hence, it is used in solar panels as an encapsulating agent, as it seals and insulates the solar cells. It protects the solar cells against dirt, humidity, vibrations, and shocks. 

Glass and Backsheet

The solar cells of a solar panel usually consist of a glass layer on the front and a protective back sheet on the rear. However, the newer solar panels with bifacial designs have solar cells, which are exposed on both the front and back sides of the panels. As such, they do not require back sheets. 


Frame- is another important component of a solar panel. Frames are usually made of steel, as it is sturdy, durable, and can hold the panel together. However, these days, manufacturers are deciding to go frameless. Instead of putting on a frame, they either use sturdier back sheets or simply sandwich solar cells between two pieces of glass. 

Types of solar panels and the materials used in them

Ground-mounted and rooftop installations usually come in two main types of solar panels - thin-film and crystalline silicon. 

1. Thin-film solar panels

Most of the thin-film solar panels consist of silicon thin-film solar cells, but cadmium telluride solar cells and copper indium gallium selenide (CIGS) are also available in the market. Cadmium telluride thin-film solar panels produce electricity by using a thin film of cadmium telluride. On the other hand, CIGS thin-film solar panels make use of semiconductor layers of CIGS to absorb sunlight and convert it into electricity. CIGS panels are, however, in the early stages of commercialisation.

2. Crystalline Silicon solar panels 

The use of crystalline silicon solar panels is far more widespread than thin-film solar panels. Crystalline silicon panels have black or blue rectangular grids, comprising of  smaller square shaped cells.  There are two different types of crystalline silicon solar panels - monocrystalline panels and polycrystalline panels. Monocrystalline panels have a more complex production process, making them costlier and contributing to their more limited use. 

1. Monocrystalline Panels 

Monocrystalline silicon solar panels are created by growing a single crystal. In these panels, a uniform blue colour is produced by the crystal framework, without any grain marks. This gives monocrystalline silicon cells the highest levels of efficiency and purity. 

2. Polycrystalline Panels

In making polycrystalline solar cells, molten silicon is poured into a cast. This method of construction, however, creates an imperfect crystal structure. It gives rise to randomly oriented crystals, with clearly visible boundaries where the crystal formation is  broken. Due to these impurities, there is a lower efficiency of these modules. The cost of polycrystalline panels is also lower than the monocrystalline panels. 

Frequently Asked Questions 

Can solar panels be recycled? 

Yes, solar panels can be recycled. Silicon solar panels primarily consist of glass, plastic, and aluminium. All these materials are recyclable and are recycled in mass quantities. However, the process of recycling is not very simple. It requires the use of advanced machinery. Following are the steps involved in the recycling of a silicon-based solar panel: 

As solar systems are becoming popular over time, disposing them in an environment friendly way is also becoming easier. There is a steadily maturing solar PV recycling market, especially in the First World nation-states. 

Are solar panels environmentally friendly?

The Solar panel is the main component of a larger solar system, which serves to eliminate the dependency of any unit (household, office, community, etc.) on conventional energy sources. Even though manufacturing a solar panel requires the use of certain non-biodegradable components like plastic, in the long run, its environmental benefits are huge by cutting down on carbon emissions. It can reduce the carbon footprint of a household by 80 percent in a single year. As stated above,  solar panels, are also recyclable. They also do not require a lot of maintenance, thus eliminating the need for  repairs and replacement of components. Thus, in this way, you do not generate a lot of environmentally unfriendly waste. All of these factors make solar panels environment- friendly. They have a much larger impact in offsetting environmental impact than one can think of. 


In this article, therefore, we provided you with a list of raw materials required to make  a solar panel. Further, we discussed the various kinds of solar panels which can be found in the market, and the components used in each one of them. We also answered some of the frequently asked questions regarding the recyclability and environment-friendliness of the solar panels. We hope that this article answers all  questions regarding solar panels, thereby  helping you make an informed decision about installing a solar system at your home or office.

Solar power is fast emerging as an alternative to conventional sources of energy, especially in tropical and equatorial countries which receive a high amount of sunlight throughout the year. In India, the government, in recent years, has been putting a lot of effort into promoting solar power. India has the highest installed capacity of solar power in the world and is a key player in the manufacturing and installation of solar solutions. It has emerged as a growing market for solar energy. However, in spite of these achievements, people are still skeptical about its potential and get scared away by minor operational issues. Switching to solar energy also requires a considerably large initial investment, which is another major reason why people are afraid of transitioning to solar systems for their houses and commercial establishments. There are other kinds of challenges that come with solar panels. In India, migration is a common phenomenon since people living in cities live in small, rented spaces. These places do not have the required space to install a solar system. Besides, as pointed out, installing a solar system requires a huge initial investment, and people find it more convenient to pay electricity bills rather than spending a lot of money to transition to solar energy. The payback period for a solar system is extremely long. However, despite these problems, in recent years, our country has witnessed solar installations at an impressive rate. 

In this article, we will ponder the question of whether a solar investment is a viable option in a middle-income country like India. We will list down some of the challenges that one is expected to face while making the transition to solar energy for their home or commercial establishment. At the same time, we will also offer insights for making the transition to solar energy a viable option for both home and business owners. We would suggest you go through this article thoroughly so that you can make a firm decision on whether transitioning to solar panels would be worth the cost involved. 

Is Solar A Viable Investment Option?

Let us look at the requirements for both residential and commercial solar systems and some of the challenges and issues pertaining to both. 

Residential Solar System

A residential solar system is one that comes with a battery system of up to 10 kW capacity for installation in homes. A residential solar system requires an investment of around Rs. 1,00,000 per kW. Considering the electricity bill of the average house is around 1000 rupees per month, installation of a solar system can result in savings of Rs. 8400 per annum (inclusive of maintenance and operation costs). Such an investment is expected to have a payback period of 10 to 12 years. The return on such an investment is likely to be around 8 percent, which is a considerable amount. 

Challenges for homeowners in transitioning to a solar system 

There are three main challenges the homeowners are likely to face in making a transition to a solar system. The following are the challenges: 

1. Budget Constraints

The first impediment to transition to a solar system is budget constraints. Investing in a solar system is a big headache for a homeowner, as it requires a lot of money. A home solar system requires an investment of Rs. 1,00,000, which is not cheap for most of India’s population.  However, people do not understand is that a solar system offers a considerable amount of returns in the long run, by making significant reductions in the money paid to the discoms as energy bills. 

2. Double Expectation

People have double expectations from a solar system. This means that they need such a solar system, which would not just result in significant cuts in terms of energy bills, but also expect all their appliances and gadgets to work during power cuts. 

3. Net Meter

The net metering system allows the owner of a solar system to claim credit for the energy they send back to the power grid. However, as simple as it might sound, net metering is more complicated than it seems. It is not easy to procure a net meter. People usually complain that it looks good only in theory, but in reality, the process of procuring a net meter and claiming credit for the extra power sent to the power grid is extremely difficult. 

Feasible Solution for Home Owner

While challenges are persistent, there are feasible solutions, as well, when it comes to installing a solar system at your house. We have listed down some of these solutions. 

1. Buying Solar System on EMI

Loans are there your best option to make an investment as large as this with. A homeowner can take a loan for installing a solar system and pay EMIs over a long period. In this way, the initial burden of investing a huge sum of money can be negated. Some banks also offer specific loans for solar systems. Otherwise, you can also take a loan for a solar system under the category of home improvement. 

2. Installing a Hybrid Solar System 

A number of companies are offering hybrid solar systems, which can help customers solve the problem of double expectations, as mentioned earlier. 

3. Discover Self Solution for Net Metering 

It is not feasible to get net metering through third parties. Therefore, the homeowner should consider the possibility of finding net metering options by visiting their nearby discom office. Some states like Uttar Pradesh, Bihar, Haryana, etc. also have online portals, which might be of help to customers. 

Commercial Solar System

A commercial solar system is a grid-connected system of up to 25 kW capacity, and these are installed at hospitals, resorts, schools, cold storage facilities, hotels, petrol pumps, offices, workshops, etc. A commercial solar system requires a higher level of investment than a home solar system, but the investment per kW is lower. It happens to be somewhere about Rs. 50,000 per kW. If your space’s monthly energy bill is Rs. 25,000 hypothetically, installing a solar system in such a circumstance can lead to savings of Rs. 14,000 per annum. Moreover, the payback time is also less (around 3 to 4 years), with a higher return on investment of around 28 percent, as compared to a residential solar system. 

Challenges for Business Owners

Just like the homeowners, business owners have to face a number of impediments when it comes to installing a solar system at their commercial establishment. The following are those challenges: 

 1. Installation Space

Just like houses, commercial establishments in a country like India, too, exist in small spaces. There are limitations in terms of the area required for the installation of solar panels. Many commercial establishments operate from rented areas and the business owners are not free to make such installations. 

2. Return on Investment

Business owners expect a fast return on investment, with an average payback period of fewer than 5 years. Thus, while they buy good quality solar panels, they tend to spend less on other components like the inverters, BoS, etc. If these components malfunction, the whole system is affected, hence, negatively impacting the return on investment. 

3. Durability

Business owners tend to focus only on the actual panels and ignore the other important component - the mounting structure. A poor quality mounting structure might fail to support the solar panels, wasting all the money that you had spent on installing the solar system.

Feasible Solution for Business Owner

While there are major challenges for business owners with respect to solar systems, the following are some of the feasible solutions available for those challenges: 

1. Customized Installation

To deal with the issue of space constraints, the business owner can opt for wall-mounted solar panels. Besides, they can also discuss with the engineers for other feasible and viable customized options, so as to derive the best performance out of the solar system installed at their commercial establishment. 

2. Analyzing all the components 

Business owners should focus on the entire solar system, rather than a single component. If they install durable components in the entire system, they won't have any complaints about their returns. Install high ROI solar panels

3. Install High Quality Products

It is essential to install good quality products offered by a reputed brand for the entire system, from the panels to the inverters to the mounting system. A failure of one component can adversely affect the performance of the entire system. 

Things to note before installing a solar system

The following things should be taken into consideration before installing a solar system at any place:

 1. Expert Guidance

While there is a lot of information on solar systems on the internet, you must always seek expert advice before installing a solar system. The expert will guide you regarding specific problems pertaining to your location, space, etc.

2. Right Product Selection

Always go for reputed brands and the right products. A solar system is a long-term investment, and you would obviously not want to incur high costs on repairs. 

3. Scope of Work 

Do have a word with the system providers and installers about their scope of work and terms and conditions of the warranty, so as to avoid any last-minute arguments. 

4. System Performance

While buying your solar panel equipment,,  make sure that they are the right fit for your system. Also, keep track of the performance even after installation. A number of apps are available these days to monitor the performance of the solar system. Be in touch with your system provider, so that you can contact them in the event of a lapse or an issue. 

5. Installer Portfolio

You must ensure that you hire the most reliable installer you can find to avoid damages to your solar panels and other equipment. Do a background check of the installer’s history. If you are not satisfied, look for other installers in your town or city. 


It is expected of all of us to be cautious before making any type of investment, and a solar system, being a huge investment, must be made in the right direction. While many people may have negative preconceptions about investing in solar panels, we would like to argue that solar panels are worth it. However, you need to be aware of a number of factors, and this article has taken note of all such considerations. Go through this article thoroughly before making the choice of transitioning to a solar system for your home or office.

Vikram solar inverters are available in different sizes and come in different specifications. Just like solar panels, the size of the inverter required for them is also rated in watts. There are three factors which need to be taken into consideration when it comes to solar inverter sizing. These are: the size of the solar array, the geography, and size specific conditions. The inverter combination can be ideally determined by the installers themselves by examining all these factors. 

2. Should I buy a monocrystalline or polycrystalline Vikram solar panel?

In the overall solar PV system, both the monocrystalline and polycrystalline Vikram solar panels serve the same function, i.e., they capture solar energy and turn it into electricity. Moreover, both these types of panels are made from the same material: silicon. Silicon is an abundant element and is also extremely durable. Therefore, they are used for making solar panels. Both these types of solar panels can be an excellent choice for your home. However, there are certain differences between the types of technology used in each of them. 

The solar cells of the monocrystalline solar panels are made from a single crystal of silicon, whereas in polycrystalline solar panels, solar cells are made from many silicon fragments, which are melted together. 

3. Can I get a subsidy when I buy a Vikram solar panel?

The government subsidy offered on solar panels differs on the basis of the brand, size, installation site, and a number of other factors. In fact, there is a difference in subsidy offered by different state governments in India. Some states, with a more solar energy friendly policy, offer more subsidies on solar panels than the others.

Factors to consider before buying the best solar battery in India 

In this section, we will look at some of the crucial elements that one should keep track of while looking for the best battery for solar inverters

1. Capacity 

The capacity of a battery is one of the most important things that constitute a battery’s overall efficiency. The capacity of the battery basically gives you a quantifiable value of how much power the battery can store and it is measured using the unit- kilowatt-hours. It can be said that the average household that can afford a solar panel system uses anywhere between 25-30 kilowatt hours each day and it is best to choose  a battery that has a minimum capacity of 25 kWh. In general, an average solar battery will have a capacity of around 10kwh. 

2. Depth of Discharge 

Depth of discharge is the variable used to measure the amount of battery capacity that can be used up before the permanent long term life of the battery is compromised to a certain extent. This essentially means that the DOD gives you an idea of how much battery capacity can be used before potentially shortening its lifespan. Thus, it's always better to have a higher depth of discharge rating. The higher the rating, the higher the usage with respect to your battery’s overall capacity. 

3. Power 

The power rating of a solar battery is another vital element that should be kept in mind. It shows the battery’s output capacity. The total amount of power that a particular solar battery can produce at a time is denoted using the unit; kw or kilowatts. 

4. Round Trip Efficiency 

Round Trip efficiency is another factor that people look for  before choosing a particular solar battery. This is basically the difference between the amount of energy required for the battery to be charged minus the available amount of energy. Just as with the depth of discharge rating, this one is also better if it is higher and gives you much better operational efficiency. 

5. Warranty 

The last thing to consider before committing yourself to any particular solar battery is to check the warranty carefully. This is an important factor because a solar battery is a one-time investment and you need to ensure that you are well covered against any type of manufacturing defects which may be unforeseen down the line. In our opinion, you should always go for solar batteries which have a minimum warranty of 36 months or 3 years. However, 5 years or more would be even better. 

Frequently Asked Questions

Q1. How many solar panels are needed to power a house?

This is one of the most common questions that we face with regards to the setting up of solar panels. The exact answer to this question is a subjective one as it is based on factors such as the size of the house, overall power requirements, and number of high-power devices that the household has to run on a regular basis.

On average, most households need around  28 to 34 solar panels in case of most average sized panels. However, if you are going for slightly larger panels, then around 20 panels or so may be sufficient.  

Q2. Which solar batteries last the longest? 

The shelf life of a battery is something that a lot of people think before buying a solar battery. And this is important because ideally, you would want to make a good investment in a battery and subsequently expect it to work for quite a few years before having to replace it.

For this reason, it is vital to invest in a solar battery that has a good track record in terms of longevity of service. There are 3 main types of batteries for you to choose from when we are looking at it from a longevity perspective. These are; lead-acid batteries, lithium-ion batteries, and saltwater batteries. Among these, lithium-ion batteries are considered to be the best option. 

Q3. Are solar batteries worth the cost?

This is a common question that comes across in the minds of solar energy enthusiasts. It's also a valid question to ask, as you need to think carefully about cost management before making an investment. It is important to mention that solar batteries still cost more than a generic diesel generator.

The benefit of adding a solar battery to your system for backup power is a very good idea in the long run from a financial standpoint and is definitely worth the investment. You can use the solar energy stored throughout the entire day to power your devices in case the grid goes down. Added to this, it's always worth to go for an eco-friendly option that will allow you to practice sustainable living. 

Q4. What is the difference between a solar battery and a normal battery? 

Regardless of the type of battery you use, the main task of a battery is to produce a chemical reaction with the ultimate aim of producing an electric current that can be used as power for various devices. The mechanism through which electricity is produced and stored has a direct bearing on the amount of power your battery can produce.

Batteries can be rechargeable and non-rechargeable. Unlike traditional batteries, the technology used in rechargeable batteries  allows for the reversal of the chemical process. Here, the electricity to the battery reverses the chemical reaction process and the battery can be recharged. 

We also have car batteries which are usually lead-acid batteries and are known as SLI batteries designed to produce quick bursts of electricity that could power the engine to start as quickly as possible. Then you also have VRLA batteries, which are basically pre-sealed batteries. In VRLA batteries, the gases produced inside are not able to leak out. olar batteries are deep cycle batteries. 

Q5. What are the basics of a solar battery? 

In the most simple terms, a solar battery is used to store the energy produced by your solar panels so that you can use it as a backup later at a different time. You can use it at night or even during cloudy days where the solar panels are not able to produce enough electricity.

If you have a rooftop solar setup with no batteries, then the power produced has only two uses; either you have to use it or it gets automatically transported to the electricity grid. Since most people are likely to use more electricity at the beginning and end of a day, a solar battery allows you to save electricity, which you can use when it is needed the most. 

Q6. How does a solar battery work? 

There are different ways to set up a home battery. In this section, we will talk about a general setup that is common among many users.

If we consider a typical solar panel setup, you will usually find that the solar panels are feeding electricity through an inverter that charges your batteries and is able to provide electricity to various household devices. Nearly all household residential solar battery systems are connected to the main electricity network and the power comes in through a meter.

Solar technology is improving continuously, and advancements are taking place at a rapid rate today. New types pieces of equipment are designed by solar panel companies to provide tough competition to the other brands in the industry. This automatically increases the efficiency and productivity of the equipment. Solar trackers are one of the many inventions that assist in providing a better power output throughout the day by following the sun’s path. 


How Does A Solar Tracker Work?

Solar trackers are designed to follow the rays of the sun at all times to maximize the power output. This is done using specific software and drivers. The sensors in the tracker react to sunlight and linked motors follow the GPS coordinates of the position in which the sensor is placed. The mechanism might sound very simple and, yet it is extremely effective. 

There are a few solar tracking systems that function with the help of compressed liquid and gas, while others work with small PV panels that can effectively power the driving systems. 


Types Of Solar Trackers

There are mainly two types of solar trackers that are used- single-axis and dual-axis solar trackers. Let us now look at the important differences between the two, so that you can easily figure out which one is best suited to you. 


Single-axis Solar Tracker:

A Single r-axis solar tracker rotates using a single point and its movement is in unison based on panel row or by section. This kind of solar tracker tracks the sun in an  East to  West direction and recently they became a part of utility-scale applications. Research shows that while several years ago, single-axis trackers were never used, only two years ago their usage increased to 70%. This shows how rapidly these trackers have become an irreplaceable part of the utility-scale market. 

On comparing single-axis solar trackers with the dual-axis ones, it can be noted that the former collects less energy per unit. However, in general, they are much easier to maintain and use.  There is also an option to choose between centralized or decentralized single-axis tracker types.  Both the types occupy very little space wherever they are installed.A single motor powers the centralized tracker and the segment of panels are moved by the driveline between rows. On the other hand, the decentralized tracker has one motor for every tracking row. 

Advancement in technology has today allowed solar rows to substitute for row and horizon shading, deal with adverse wind situations, and diffuse light. Thus, even when there is hardly any sunlight, the tracker is able to catch the available diffused light. In certain advanced solar tracking systems, there are system-level monitors that allow tracking to continue despite harsh weather conditions. 

There are a few limitations of these trackers, as installing them becomes a problem in higher topographies. However, with new technology, this is improving and now we have trackers that are accustomed to colder climates and also  in sitations when there is extreme snowfall. 


Dual-axis Solar Tracker:

Experts have suggested using dual-axis solar trackers since they capture the sunlight directly as they rotate on both X and Y axes. The arc of the sun varies from season to season and this determines the rotation of the earth, which is not always the same. However, even with the ever-changing positions of the sun, the dual-axis solar tracker can track sunlight. This is the main reason, why they are considered to function better than single-axis solar trackers. 

These trackers yield more energy. In fact, it is almost 30 to 45 percent more energy than the other tilt-solar panels. They are considered ideal for residential areas even though they are becoming more common for utility-scale applications. 

To allow the solar panels to reach a better and higher range angle, these trackers are installed at a height, such as an elevated platform. 20 panels per unit can be covered by a single dual-axis solar tracker. However, there is a limitation to this. You will have a hard time reaching the elevated post while cleaning the tracker, which is something crucial for its maintenance. You can use the space above the place where the tracker is installed for agriculture or similar work. Rooftop solar systems are still being developed and it will take a few years before they become popular. 


Does Tracking Of The Solar Panel Throughout The Day Give More Energy?

It is true that tracking of the solar panel throughout the day gives more energy as compared to its stationary counterparts. The exposure to the sun is automatically increased with the help of a tracker, as it tracks the path of the sun and even when the light is diffused, the tracker can capture some sunlight. Depending on the geographic location, a tracker produces almost 10%-25% more energy. 

They generate more energy even after occupying the same amount of space as the standard solar systems. Thus, they optimize land usage which is always a great thing. There are certain places in the world where there is ‘Time Of Use’ rate plans of solar power. This means that during peak times of the day, the utility purchases the power generated at that time. Even for situations like these, tracking the solar panels benefits the utility industry more. 

Despite these advantages, there are a few disadvantages as well. They tend to require more maintenance and frequent washing for proper functioning. They are also slightly more expensive as compared to the standard types of solar trackers. These trackers are also a problem in cold places with snowfall and hence, it is best to install them in places with warm climates. 



If you own a solar system, you should definitely consider getting a solar tracking system to enhance the power output. The initial costs and expenses of maintenance are covered by the exceptional performance of the trackers. They are worth the investment, because of how much more energy they are able to produce when compared to a standard solar system without a tracker. 

The use of solar panels has gradually become more and more widespread in many places of the world, where it was not considered an option not too long ago. Still, there are quite a few doubts regarding the efficacy of solar power and whether they are able to meet the power requirements for high load devices such as Air conditioners and Refrigerators. In this article, we will tackle those questions head-on and tell you the ways in which you can easily run air conditioners and other high power devices using your solar panel setup without having to spend a fortune. 

Air conditioners are widely used owing to the rise in global temperatures creating oppressive conditions during the peak of summer in the subcontinents. ACs are now common not only in homes but are also becoming more and more common in commercial establishments of various sizes including the micro industries. With the right solar panel setup, you can save a lot of money in running multiple ACs or continuously running ACs for hospitals, schools, and other public and private spaces. 

Especially in countries like India, the high temperatures witnessed during summer coupled with the high cost of running air conditioners, the conditions are ripe for higher solar panel setups which facilitates consumers to make significant savings in the long run.  


On-grid and Off-grid systems 

You can run air conditioners on both on-grid as well as off-grid solar systems. The only difference is that in on-grid systems you can run your appliances even when there is no electricity, which is not possible in the case of off-grid systems. If you are using an on-grid system, you should ensure that you install kVA inverters to handle high loads. It is also recommended to install a higher kW worth of solar panels if your expected AC usage is higher than average. In general, it is recommended to run air conditioners within a capacity range of 3 kW to 10 kW depending upon the number of  ACs you're expecting to run and their average durations. In the case of on-grid systems, you can easily support the running of multiple ACs in commercial office spaces or residences with electricity bills ranging from around 1 lakh to 5000-10000 respectively. Apart from this, one of the major reasons for setting up an on-grid connection is that you enjoy the benefit of net metering policies to avail  credit in your monthly electricity bills.

In order to run an on-grid system, you will require government approval as well as dedicated roof space to set up your solar panels. The benefit  of installing on-grid systems is that the government offers a lot of added incentives for users. This manifests in the form of subsidies which will help you to reduce your costs to a certain extent. You can get different rates of subsidy in different states. General conditions are that the system should be a grid-connected, battery-less, with you as a domestic residential consumer to claim the benefits. 

AC Wattage and Current Requirements 

When we talk about air conditioners as appliances consuming more power, we are referring to two main aspects which you need to keep in mind. Air conditioners and other such appliances have a high draw of initial current and demand higher wattage to start with. Here we will discuss the max wattage and the ideal maximum kVA panels that are required for ACs of different tonnage. 

In the case of a standard 1 ton AC which is used by most small establishments and residences, the max wattage requirement would be somewhere around 1300 watts or 13 kW.  For this kind of power requirement, we would recommend a 1.6 kVA solar power, assuming there is a 0.85 power factor. In the case of higher powered ACs such as 1.5 tons, a 2.4kVA solar panel can be used to match the 1900 watts or 1.9 kW requirements. If this is still not enough and you need to run a 2 ton AC, then you will need to have a 3 kVA solar panel for maximum power supply, as the wattage requirement will be somewhere around 2500 watts or 2.5 kW. 

Preconditions to setting up an On-grid Solar Panel System 

If you wish to set up a solar panel system to run your ACs, it is vital for you to understand the concept of solar net-metering which helps you to calculate any excess power that is being generated by your solar grid system. The two main conditions that you need to fulfill while 

setting up an on-grid solar panel system are as follows : 


  1. Ensure that the total PV capacity in the local distribution network does not cross 30 percent of the distributor transformer capacity. In order to understand this better, consider this example;a distribution network that is powered by a  250 KVA distribution transformer cannot have more than 75 kW of total solar PV capacity connected to itself. 


  1. The total PV system capacity that is being proposed cannot be more than the sanctioned or contacted load of the service connection. In case this rule is breached and the PV system capacity is higher than the sanctioned connected load, you will need to apply for service connection load enhancement. Only after applying for  this, your solar net-metering application can be submitted.  


Frequently Asked Questions 

1. How many solar panels do I need to run a 1.5 ton Air Conditioner? 

The number of solar panels that you require to comfortably run a 1.5 ton air conditioner depends upon the maximum kVA of the individual solar panels. However, as a general rule of thumb, we can recommend that you should get around 10 panels with a wattage of around 250 watts each. In the case of 1 ton AC, it is best to set up 6 solar panels with 250 watts each. 


2. What appliances can be used with solar power? 

Solar panels perform the task of converting light energy from the sun into electric energy that can be used by a whole gamut of different everyday appliances used daily. The transformed energy is then stored in batteries and used by the different appliances as per their requirements. It is fair to say that you can run almost any electrical equipment using solar energy which generally runs using normal electricity. These include things like lights, fans, TVs, computers, PlayStations, and many more. Some people seem to think that it is not ideal to run Air Conditioners and Refrigerators using a solar power system, but this is a myth that has been disproved time and again. 


3. How many batteries does it take to run an AC? 

Batteries are devices which store the converted light energy so that various household devices can utilize the energy  to run everyday functions. In most cases, off-grid solar panel setups require batteries to store the power, which can be used later when there is no electricity available. Most people would recommend  a 4 battery setup with 150 mAh batteries if you are running a 1 ton AC. This might change as the AC capacity increases to 1.5 or 2- tons. 


4. Can I run a 1.5 ton AC  on solar without batteries? 

This question generally comes from those who wish to set up an on-grid solar panel system for their residence. We would recommend you to figure out the power of your solar panel and measure the total amount of power that your AC needs  to function. In theory, you can run a 1.5 ton ac on solar without batteries, provided that there is enough power being driven from the solar panel into the appliance. It is important to mention that a 1.5 ton air conditioner consumes somewhere around 1.6 kW of power. We would ideally recommend you to go for a 2.5 or 3 kW power system if you are planning to run a 1.5 ton AC without batteries using solar power. Overall, it is better to go for a higher kW capacity as you will be running other appliances as well along with your AC, which will consume additional power and put higher stress on your solar panels. In short, it is possible to run a 1.5 ton air conditioner without using a battery, but you need to do adequate research about your power requirements and whether your panels are capable of meeting them. 


5. Why should you go for a solar AC module? 

There are a few important benefits that you will enjoy if you choose to go for a solar AC module instead of a DC variant. The first major advantage is that an inverter battery is not a mandatory requirement in the case of solar AC modules. Another reason for the popularity of AC modules is that the installation is very simple and straightforward and takes about 15 minutes or so. Other than that, you also have the panel wattage monitoring mechanism which enables you to always stay in control and fish out any irregularities if they should arise. The last thing to mention regarding the benefits of AC modules is that it gives up to more than 25 percent power generation as compared to DC modules. 



In this article today, we attempted to answer the main question of whether it is possible and feasible for you to run your AC on a solar-powered system. We discussed numerous themes and sub-themes related to this topic in  this article and we expect that you acquired some valuable information that you probably were not aware of before. We dispelled the myth that it is inadvisable to run air conditioners on solar power setups and we also explained the reasons why it could prove to be a very good solution for a host of Indian families owing to the harsh summer conditions and the costs of running air conditioners regularly. 

Then in the following section, we had some discussions about on-grid and off-grid systems. We outlined their main differences and how they function and what additional requirements they have. Next, we addressed the questions surrounding the wattage and current requirement of air conditioners and which panels would be suitable for different air conditioners based upon tonnage considerations. With that, we bid you farewell and we wish you the best in your environmentally sustainable endeavors until we meet again. 

The solar power industry has really taken off in the last few years worldwide and also across major parts of the subcontinent. In India as well, many sections of the agricultural professionals have turned to solar-powered water pumps for their irrigation requirements.  Solar-powered pumps are nothing but water pumps, which use solar energy instead of traditional electricity. The recent surge in solar powered pumps in the agriculture sector is largely because of the cost-effectiveness and durability.. Additionally, they are also quite easy to install and requires much less maintenance compared to the more traditional electric water pumps. 


In this article, today, we will try and give you some vital info on how you can run solar-powered water pumps step by step so that you can use them according to your requirements. Keep in mind that the average shelf life of a solar-powered water pump is anywhere between 15 to 20 years on average. This kind of system is ideal for areas and regions where there is unreliable supply or availability issues regarding electricity. So sit back and let us take you through this journey of solar water pumps for home usage and we are sure that by the end of this article, a lot of your doubts will be cleared. We will start off the discussion by outlining some of the major benefits of solar-powered pumps and then move on to some more intricate issues that are relevant to the topic of discussion at hand. 

What are the benefits of a solar-powered pump? 

There are 3 main benefits of shifting to a solar powered pump from a traditional water pump that runs on electricity. Most users have stated that the main reason for their choice of shifting to solar pumps from electric water pumps, is because it removes the dependency on the grid system. Most pumps today are totally dependent on the grid and if there is a power cut, everything comes to a sudden standstill. 

Another big reason for the sudden surge of solar power pumps is that they are convenient to use.  This is because the pump can use solar energy during the day and the stored power will allow you to use the pump at different times of the day where there is no sunlight. 

If you are involved in agriculture and you do not enjoy the overdependence on electricity, then solar water pumps for agriculture can be a godsend for you. For instance, there are a lot of handpumps still in use in India, which can be mounted on a well without causing any kind of disruption to your electric well pump. This allows you to have a backup option to deal with unexpected power outages. 


Solar Pump Solutions 

The type of solar power setup you wish to go for will depend upon your needs and requirements related to water supply.  There are two main options that you have at your disposal. 

If you are looking to install a solar water pump for your home to get water for household chores and such, we would recommend you to go for a 2  off-grid solar system, if you have a water motor that  has a ½ HP rating. 

In case the water pump is of a higher HP rating such as 1 HP, the ideal choice would be to go with a 3 kW solar system. 

2 KW Off-Grid Solar System 

This type of  solar pump setup is ideal for large homes as well as small and medium-size commercial establishments, shops and offices. This type of a system can run more or less anything when it comes to electrical appliances. The only thing it is unsuitable for is running air conditioners. You will get around 8 to 10 units of generation every day and it is also easier to install, as it takes only 200 square feet of roof space. 


3KW Off-Grid Solar System 

If you are looking to set up a solar system for a big house or a larger shop or commercial establishment, then this is the way to go. This type of  solar system is capable of producing up to 15 units of power every day and requires slightly more rooftop space to be set up. 

How does a Solar Water pump function? 

Just like any other regular water pump, a solar water pump, pumps water to different taps and outlets as per requirements from your main water storage tank. The difference is that a solar-powered pump manages to do this without having recourse to dedicated power lines. Solar pumps can be used effectively for regular day-to-day activities, as well as commercial activities related to agriculture, irrigation and animal husbandry. One of the basic ways in which a solar pump differs from a regular water pump is that, it uses DC current instead of AC current, which is used by most traditional electric water pumps. 

Most of the solar pump models are ideally designed to be used as a part of off-grid systems and they are also highly efficient in terms of their power utilization and task management. As it uses DC current, it does not have to suffer any loss of power while converting DC to AC and vice-versa. This allows you to maximize pumping while at the same time minimizes  the use of power.. If you use PV-Direct, you can directly pump from the solar panel without using separate batteries for the purpose. Those who use solar powered devices know that storing the power in batteries can result in loss of power to a certain extent. The possibility of this happening is completely negated as the water is stored in a cistern or a tank and pumped from there directly to various outlets. In case of a cistern, you will have a removable lid at your disposal where-as in the case of a tank, it will generally be sealed. 

Submersible vs Surface Solar Pumps 

Solar Pumps generally come in two different varieties. A submersible pump, as the name suggests, is a pump that is installed under water. These are generally found submerged in a well although they can also function inside a pond or a stream, if they are raised slightly from the bottom of the water bed. 

A surface pump on the other hand can only be installed above the surface of the water and is equipped with an intake hose which feeds the pump by taking water from the source. Then a separate output hose performs the task of feeding the tank. Make sure to keep the pump close to the water source as that helps in effective water intake into the pump. The vertical distance between the water source and the pump should be as low as possible to ensure effective passage of water intake. 

Linear Current Booster (LCB)

A solar pump requires a solid boost before functioning to  full throttle. Once it starts, a pump requires a high surge of current initially, but it does not require high voltage. This is why, sometimes, a solar pump may struggle to power itself effectively in the dim morning light of dawn. And to address this issue, we have a device called a Linear Current Booster that is installed in between the solar panel array and the pump in order to ensure current output so that the pump can perform its task to the best of its capacity in dimly lit conditions. This is achieved by dropping the voltage output as this does not affect the water flow as much as the current requirement. Ultimately, this is great for giving higher levels of convenience and the option to have uninterrupted power supply during different times of the day when the sunlight is not at its peak.  

Float Switches 

In case of solar water pumps for home usage, some people use a float switch, which is a device that is used to control the turning off or on of the pump based on the water level. In case of a pump-up switch, it will turn on the pump when the water is low and turn it off when the water level is high. On the other hand a pump-down switch will do the opposite and turn the pump off when it is empty and vice versa. There are also LCBs which are able to connect the float switch to its input system without directly connecting to the pump. Always be sure to check the LCB manual thoroughly for the details on this matter. 


Water Pressure 

In case of water supply to a house, there has to be adequate water pressure in the pipes to allow the water to flow freely. This is measured in PSI or pounds per square inch. In general, most houses have a PSI rating of around 40, although 20 PSI can be enough for your requirements. There are different ways to achieve higher water pressure and gravity. Feed is the most basic and common system that we would recommend. This mechanism uses the power of gravity by setting up the tank on  top of the house. 


Booster Pump Mechanism

You might very well find yourself in a situation where it is not possible for you to set up a high storage tank that is placed above your house.  In this case, you have the option of using a small booster pump to ensure that enough pressure is created in the pipes connected  to the system. This pump needs to be connected to a battery bank. This allows you to have access to water at any point of time during the day by creating conditions for effective pressure. It is also very important to check the technical specifications of the booster pump that you will be using to gauge PSI capability, while also getting a good idea about how many amps will be required to set up the process by  which pressure is created. 


In this article today, our main focus was to give you detailed and comprehensive reviews of the process and steps involved in the setting up of solar-powered water pumps. We started off with a short introduction on what solar pumps are and how they can be beneficial to different people for personal as well as professional purposes. We also spoke at length about the various kinds of solar water pumps for agriculture that are in vogue and the different benefits it offers as opposed to traditional electric water pumps.  Because of the cost-effectiveness of solar-powered pumps, a lot of households in India are turning to this new form of texhnology and as a result they are reaping significant long term benefits. 

Through the course of this article, we have also discussed numerous steps and choices that are important to consider before deciding on a specific solar power setup that you are planning to undertake. Make sure to read these steps carefully and we also encourage you to do further in-depth research if required. Hopefully, we were able to cover some useful topics in this article and we also hope that it finds some good practical use for your requirements. With that we bid you farewell and we wish you all the best in your efforts to get a solar-powered pump to meet your personal or professional water supply requirements. 


In this article, we will discuss one of the most important aspects of creating a solar panel system, which is the battery. Regardless of whether you are planning to move off the grid or add some extra energy storage capacity to your existing grid-connected system you have two main options to choose from, in terms of battery types. These are Lead-acid and Lithium variants and both have their own set of pros and cons. We will discuss some of these in detail and give you the most comprehensive picture regarding which battery type is suitable in different situations and setups.

For starters, we can say that Lead Acid batteries offer a tried and tested technology that costs much less but require a lot of rigorous consistent maintenance. 

On the other hand, lithium is one of the best current battery technologies present and they are known for having longer shelf lives and a higher degree of efficiency. It does however cost more than lead-acid battery types. In the following section, we will discuss some of the specifics regarding the two types of batteries. 


Flooded Lead Acid (FLA)

This type of a lead acid battery is distinguished from others by the submergence of their plates in water. Not only do they require regular and thorough checking, these batteries also require refilling every one to three months, so as  to function at optimum efficiency levels. If sufficient care and testing is not carried out, the warranty on these products may become void, which is to be ensured.. Also, FLA batteries need to be kept in a very well ventilated enclosure as they emit gases. These gases need to be expelled through a good ventilation system. 


Sealed Lead Acid (SLA)

This is the second variant of lead-acid batteries which are very popular in the market, when it comes to people setting up solar panels. SLA batteries can also be divided into two different types. These are called Absorbent Glass Mat(AGM)  and Gel which are slightly different from one another and at the same time shares quite a few properties. Not only are these batteries spill-proof, they also require the most minimum levels of maintenance on a daily basis. 


The main point of difference that sets apart AGM batteries from Gel types is that the latter tend to have relatively lower charge rates as well as a lower and more limited output capacity. Gel batteries are also not ideal for handling higher amounts of charge current. This also means that they require frequent charging and are also not capable of consistent high output levels. 



Lithium batteries are the last option at your disposal and are often considered to be state of the art batteries, in terms of technology used and the efficiency they offer. Even among the lithium battery models, there are some which are better than others in case of usage with solar panels. 

The most recommended lithium battery chemistry to use with solar applications is Lithium Iron phosphate which is  also commonly known as LFP batteries in many local markets around the world. Not only have lithium batteries proven to last t longer, they can also be put under great pressure with deeper cycles and higher loads. Another important thing to consider is that they do not require a good ventilation system like the lead-acid battery variants. 

Since they represent the best in battery technology at present , lithium batteries are costlier compared to the rest mentioned here. However, they are more efficient and this can potentially save some money over time.. This is because you might end up paying significantly less per kilowatt-hour of capacity in the case of lithium variants. 


Key Differences between Lead Acid and Lithium Battery 

Life Cycle 

One charge cycle is referred to as the total time taken to discharge a battery by connecting it to appliances and then recharging with the help of panels. In the case of solar panel batteries, their efficiency is measured not in terms of the number of years the battery can run for, but the number of cycles they are capable of, before they wear out and expire. 

An analogy that might help you to understand this concept better is the things you consider before buying a used car. Obviously, the mileage is a lot more important than the year of production in order to give you an idea whether it's worth buying or not. 

It's more or less the same in the case of batteries. It all depends upon usage frequency. For instance, in the case of a vacation home, a sealed-acid battery may go through 100 cycles in 4 years. The same battery will go through more than 300 cycles in the case of a full-residence in roughly the same amount of time. Obviously in this case, the one that has gone through lesser cycles will be in better shape. 

An important factor that has a bearing on the cycle life, is the depth of discharge. It is used to denote the capacity of usage before recharging the battery. Deeper discharges tend to put more pressure on the battery and this results in the shortening of life cycles. 


Depth of Discharge 

As mentioned before, the discharge depth basically denotes the overall usage capacity of a battery before it gets recharged. So for instance, if you use 3/4th of your battery’s capacity, the discharge depth will be  75 percent. It's important to note that batteries actually do not discharge fully when in use. They also have a recommendation telling the user the ideal depth of discharge rating before it requires a recharge. 

In the case of lead-acid batteries, it is recommended to use up to 50 percent of its discharge capacity before recharging the battery again. Beyond that, there is a chance of a negative impact on the lifespan of the battery. 

On the other hand, lithium-powered batteries are equipped to handle deep discharge levels of upto 80 percent. This automatically translates to a higher usage capacity. 



It is common knowledge that lithium batteries are generally more efficient across all devices. They are capable of storing and using more solar power. 

Lead-acid batteries have around 80-85 percent efficiency, depending on the particular model in question. So for instance, if you have 1000 watts of solar energy absorbed by the batteries, you will have around 800-850 watts available for usage after the charging and discharging process. 

Lithium batteries on the other hand are more efficient and generally have an efficiency rating in the high 90’s, depending upon the model and other specifications. 

Higher efficiency levels entail that batteries charge faster. Also, depending upon the specifics of your setup, it could also mean that you don't need as many solar panels or you can easily work with a smaller backup generator and lesser battery capacity. 


Charge Rate 

As lithium batteries are more efficient, they can also charge much faster and thus saves time. As they are able to handle a higher degree of amperage from the charger, they are equipped to refill much faster as opposed to the sealed lead-acid batteries. 

The rate of charge is expressed as a fraction such as C/5, where C = the capacity of the battery is amp-hours(Ah). So this means that a battery with a 430 Ah rating would receive 86 charging amps. 

In the case of Lead-acid batteries, they are a lot more limited in terms of charging capacity. This means that the battery is at risk of overheating if you charge it continuously for too long. Apart from this, another issue with these types of batteries is that the charge delivered gets weaker and slower as you approach maximum capacity. 

Lead acid batteries are capable of charging at around C/5 during the bulk phase at around 85 percent capacity. After the bulk period, the charger slows down automatically in order to top off the batteries. So, the conclusion that is drawn from this discussion is that lead-acid batteries usually take a longer time to charge and in some cases it might take up to twice the amount of  time compared to a lithium-powered battery. 

Energy Density 

In terms of mass and weight, it is a general rule of thumb that lead-acid batteries are heavier in terms of weight compared to lithium variants. For fixing solar panels, most of the installers can handle the extra weight without any issues, so no need to worry. However, if you are planning to do DIY style, then you should know that lithium batteries may prove a bit more tricky to install without any kind of professional help. We recommend you to get some help in lifting and fitting the panels. 

However, like everything in life, here also you have a trade-off to keep in mind. Lithium batteries have a higher energy density as compared to lead-acid variants. This means that lithium batteries are able to fit a higher amount of storage capacity in less space. 


Lithium vs Lead Acid: Which battery is ideally suited for you? 

In this section, we will look at different applications and try and give you the benefits of using each different battery variant. 


Full-Time Off-Grid Assistance 

In this case, we would urge you to go for either Flooded Lead Acid or Lithium battery variants. In case you plan to live off the grid full time, we would highly recommend FLA battery types. This requires regular maintenance. However, if you plan to undertake heavy usage, Lithium battery types are the best bet. 


Off-Grid Cabin/Vacation Home

If a solar panel system is set up for your vacation home or cabin, it is likely to be in use for a few days in a year on particular occasions. For this, a Sealed Lead Acid battery variant is recommended  as against FLA batteries, which requires regular maintenance.. In these situations, we always recommend SLA types as they are a lot more resilient and are capable of functioning over longer periods without having to undergo regular maintenance checks. 


Battery Backup System 

In this case, we would once again recommend SLA battery types. If you are setting up a solar panel for emergency power requirements during power cuts, then you will not be using the system all the time, but only on certain occasions. The requirement, in this case, is to have a battery that you use occasionally  and that doesn't demand too much maintenance. This rules out  FLA variants.  Additionally, you should not spend on lithium batteries for a backup solar power setup. Thus, the only other viable option left is to choose  SLA types. 


Remote Industrial Use 

You can go with either an SLA battery or a lithium battery for this type of setup. Industrial sites or areas with high power requirements should always go for lithium batteries as they would offer you the best price to performance ratio. 


In this article, we tried to give you some pointers on various types of batteries best suited for different solar panel setups. We started off with a small intro on the various options available and what they offer. Then,  in the subsequent sections, we tried to offer more details in terms of FLA, SLA, and Lithium battery variants and where they should be ideally used. Hopefully, this article finds some good use for you and you can get the right kind of batteries for your solar setup as early as possible.

Factors to consider before buying a solar flashlight 

In this section, we will discuss some of the important things that you should keep in mind while buying a flashlight. Hopefully, these markers will enable you to make a more informed choice based upon your own specific requirements. 

1. General Type and Brightness 

Solar flashlights can be divided into different types based upon their maximum brightness levels and this point is important to decide how you are planning to use your torchlight. For instance, if you are searching for something that could primarily function as a security lamp, then you should go for LED solar security lamps that are high in brightness levels.

The brightness is quantified with the help of a unit called lumens. Below, we have mentioned the ideal lumen rating for different torch lights, based upon their requirements and usage expectations. 

For step lights, the range of solar flashlights should be between the value of 12 and  100 lumens. In the case of landscape solar lights we would recommend a lumen range of 50 to 130 lumens. Then we have hardscape solar lights which might be used as wall lights.

For these purposes, your solar flashlight should have a lumen range of 50 to 185 lumens. Another popular use of torch lights these days  is to use them as path solar lights. These need to be significantly brighter than some of the rest and should have a lumen rating of anywhere between 100 to 200 lumens. If you are looking to install solar lights for your pond or swimming pool, the best lumen rating is anywhere between 200 to 400 lumens. 

2. Battery 

The battery backup is one of the most important things to consider, in the case of any remote electrical device. There are a few different types of batteries that are used by different solar flashlights. There are roughly four types- consisting of lithium-ion, NiMH, lead-acid and NiCAD. All of them are capable of giving you more than decent performance. However, the lithium-ion type stands out as the most popular choice. This is because they generally tend to have higher performance capacities whilst also being the most compact in size. 

3. Solar Panels 

The type of solar panel used by your flashlight determines  the overall performance of your solar flashlight. tThere are three main types of panels that are used by most Chinese and Indian solar flashlight manufacturers. They are monocrystalline, polycrystalline and amorphous  variants respectively. 

Although the three types of panels are capable of good performance, the monocrystalline panels are considered to have the highest degree of effectiveness. On the flip side, the monocrystalline variants are also a bit more expensive than the other two. So consider your options carefully. 

Frequently Asked Questions 

Q1. Can solar powered lights be charged indoors? 

This is one of the most common questions online regarding the charging of solar torches and any  kind of solar powered lights. A lot of people seem to think that you can only charge a solar torch by exposing it to direct natural sunlight for a specific period of time.

Although charging from sunlight is recommended and natural, you can also use household light indoors to charge your solar torch light. In order to charge your solar torch light indoors, you should place it directly underneath a bright light source, preferably LED. The key here is to place it as close as possible to the source of light to charge it in the least amount of time. 

Q2. Do solar lights charge on cloudy days? 

Another one of the most common questions that we have found on the internet regarding the usage and charging requirements of solar lights is whether solar lights can be charged on cloudy days?.

On cloudy days, the solar panels are not getting access to direct sunlight and hence charging might prove to be more difficult or simply end up being more time consuming and inconvenient. But the good news is that, although your solar panels do not get direct sunlight on cloudy days, the panels still get enough light to charge themselves. This is because of the fact that the solar irradiance is still transmitted from the sun to the Earth even on the gloomiest days. 

Q3. How big should my solar torch light be? 

This is a difficult question to answer as it largely depends on your usage, expectations and needs. If you are only looking for a torch light for your home usage, then it can be bigger in size without any issues as you will be using it mainly indoors.

On the other hand, if you’re looking for a light that will help you to navigate outdoors during the dark, then we would recommend you to consider smaller and more compact ones. The smaller they are, the easier they are to carry and use. However, there is a bigger chance of  misplacing some of the smaller ones.

Solar energy is the energy source of not only the future but also of the present. A lot of people are making the shift to renewable solar energy from electricity and this has created an increased demand in the market for solar panels in developing countries like India. However, a lot of people are still unsure about who to trust when it comes to installing solar panels and getting the entire process going. In this situation, a lot of enthusiastic individuals have chosen to go the DIY route when it comes to installing solar panels. And indeed, doing it yourself can prove to be a very rewarding experience. Still, many people  are nervous at the thought of giving it a go and this is what we wish to change. After going through this article you will have a decent idea regarding how to install solar panels at home.

In this article, we will go through a detailed step by step process of how to install solar panels from the perspective of a newbie who has very minimal knowledge about solar energy in general and the installation of solar panels in particular. Irrespective of whether you are looking to install a grid-tier system or an off-grid setup, we will attempt to outline all the important details surrounding the art of installing solar panels in this discussion. Note that we have tried our best to keep things more or less relatively simple so that the average layman could get a fair idea about how this process works. If you feel that the information in this article is not enough to help you get started, then you can definitely do further research and get into more detail. 

Planning and Safety Considerations

Before getting into the technical aspects of installing solar panels, we would like to give you a few pointers on planning and safety aspects that you should be thinking about. First of all, make sure that you have a clear list of the things that you have purchased and whether they cover all of the non-essentials such as wiring, tools etc. If you have ordered the equipment online, make sure that all of it has arrived in proper condition and that nothing is missing or damaged. Also make sure to check the safety regulations thoroughly that are mentioned in the instruction manual. 

Besides the main panels and accessories, there are a few other things you need to purchase in order to carry out successful installation of the solar panels. The first of these things that you need to consider is the wiring equipment. You need to get your hands on an electrical wiring diagram that will help you determine the length and specifications of the wiring that you will need for your solar panel setup. You can use this diagram to get the right materials from your local hardware store. 

Junction Box of a Solar Panel

As for junction boxes and splices, make sure that they meet the voltage and ampere requirements of the circuit you wish to include them in. Also be sure to use insulated lugs and approved splicing devices only. If you are using outdoor boxes, they should be rated separately for outdoor use. 

Then we come to the question of AC breakers. AC breakers are there to import and export AC power from your solar equipment. Also make sure to check your breaker panel for a list of compatible options for circuit breakers. AC solar circuits can also be combined using sub-panels. However, make note of the fact that sub-panels will prevent you from installing load breakers inside them. Also, if you do choose to go with sub-panels, make sure to size them with moderate headroom so that they can cover the output coming from the solar circuits. 

General Electric AC Breaker

Next you need to consider the issues of AC disconnections and fuses. Most of the solar panel system will require you to install a lockable safety disconnector anyway. In the case of conventional connections, a non-fused manual disconnect is required. This could be included in your system so make sure to check that properly. In case you plan to use a line-side tap connection, a fused manual AC disconnect is required. The fusing ensures that the circuit does not suffer from accidents due to overcharges. In order to get the specific details regarding the mounting of AC disconnects, it's always better to check with your local authorities.

PV Meter

PV meters are another essential element that helps you to keep track of your solar panel’s performance on a daily basis. If you have a grid-tier system in mind, then you definitely need a PV meter. In other cases, all you need to do is just install a meter socket or a base. 


Conduits and Meters 

Always be sure to use a larger conduit than what is specified in your plan. Also check with your state and municipal authorities to see if the solar wiring has to be transitioned to conduit before leaving the array. You have two different options in terms of conduits, EMT and ENT. EMT is a thin-walled conduit that has to be grounded and is generally made out of steel. ENT on the other hand is non-metallic and does not need to be grounded. ENT conduits are generally more cost effective. However, most building codes do not allow its usage so make sure to check with your local authorities. 

As far as mounting is concerned, you have two different options at your disposal. Ground mounting will require you to create a concrete bracing with 2 or 3 inch mechanical tubes. You will also need a lumber that will act as the base of the build and help to hold the pipes in place. 

Titebond 61121 Metal Roof Sealant

For a roof mounting setup you will need to buy several tubes of roof sealant in order to prevent leaks as well as damage from wind and other weather elements. 

Safety Considerations

Solar panel installation involves quite a few hazardous steps as it requires you to undertake electrical work as well as some heavy lifting as well.  Because of these reasons it is vitally important that you take all of the essential safety precautions. 

The first thing that is important for you to secure is the right combination of protective equipment. Solar equipment can cause cuts, lacerations or puncture wounds if it's not handled properly. We would recommend you to wear eye protection and also wear full shoes  as well as gloves. Also make sure to remove all types of metallic jewelry while handling solar equipment. Lastly, we would recommend you to wear long sleeves during mixing concrete. Also be mindful to use a roof anchor and some form of safety harness while undertaking roof work. 

A full body harness

Fall protection is essential if you plan to install a roof-mount system. First thing to do in this regard is to install roof anchors and make sure to have a safety harness attached whenever you are on the roof. Roof ready boots are also very helpful in ensuring proper safety and preventing unforeseen accidents. Furthermore, a boom-lift or a scaffolding can help you a great deal in ensuring the best possible access to high places. 

In the case of ground mounted solar panels, dig safety is of paramount importance. Always be careful to alert local municipal or district authorities before undertaking any sort of digging projects. This is recommended to avoid hitting any underground pipes or electrical lines. It's also best advised to avoid wet concrete while laying the panels as they can cause caustic burns. We would also ask you to wear a range of protective gear such as gloves, N-95 masks etc if you are planning to mix your own concrete. It's also good to have the eyes of a trained and experienced operator on-site especially if you are using heavy equipment. 

Next we come to the question of electrical safety requirements. The first important thing to remember is to remove all metallic jewelry from your body including things such as wrist watches. Always be sure to keep a multimeter on stand by and use it before you get started to ensure zero voltage conditions before beginning to use the conductor and terminators. Make sure to keep all of your wiring striped and terminated. This should be done using a torque wrench wherever ever and wherever necessary. Lastly, we would recommend you to route your wires properly away from sharp edges and surfaces as they could cause long term damage to the wires. 

We would also like to end this section with a few brief tips on lifting safety considerations. The first important thing is to ensure that the entire process is planned out thoroughly and enough planning has been undertaken to guard against unforeseen contingencies. If there are heavy winds, it's better to have two or more carrying each panel to ensure maximum safety. Always be sure to lift heavy things by squatting so that you do not put pressure on your back. Another thing to remember, is to try and minimize body’s turns while moving heavy equipment and to keep the weight close to your body so that you don't have to support it just with your arms. Lastly, we would always recommend people to use a hoist or a crane to lift heavy equipment over long heights. 

Management of Wiring 

Good wiring management is responsible for giving you high quality performance from your solar panels in the long run. Despite this, it is a factor that is often overlooked by many. Some of the fundamentals to keep in mind in this regard is to plan your wiring from before so that the wires do not interfere with access to the array. We also highly recommend you to use wire clips in order to secure the factory wire leads effectively in place. This is to protect them from the elements of nature such as winds for example. Also, you can use the clips to run the wires along the railing of the solar panels themselves. There are some solar panels which use spring clamps which can also be used to secure the wires. In this section we will give you a few pointers on how to plan your wiring effectively. 

Electrical Connection 

The path of your wiring will be different based upon the type of system that you will be installing. We will attempt to outline the specification of different systems with respect to the wiring in the section below. 

In the case of a grid-tie wiring path, the PV strings will attach to a junction box. The junction box in-turn will attach to the solar inverter and the AC cable output will connect to the main/sub-panel. 

For a grid-tie wiring path, the PV panel is connected to the micro-inverter. Micro-inverter is then connected to the trunk cable as the trunk cable moves into the junction box. Finally, the junction box is connected to the main panel and your wiring is complete. 

The final option at your disposal is to go for an off-grid wiring option. Here, the PV strings attach to the combiner box which gets connected to the charge controllers. Charge controllers then get attached to the battery bank. The battery bank is connected to the inverter and the inverter finally connects to the load panels. 

For Off-grid DC wiring setup make sure to thoroughly check all of the AC, DC and communication connections to make sure that everything is connected and torqued as per requirements. You can also mark the connection with a paint pen to know which ones have been torqued. If you bring combined DC power from a solar panel array to a power centre, make sure to terminate your solar positive wire at the Solar Input busbar and not the DC Batt busbar. Finally, ensure that you use a meter to check the terminals and busbars and see if they are operating at a safe voltage before moving on with the rest of your build. 


Array Maps for Micro-Inverters/Optimizers 

In case you choose to go for a system that uses micro-inverters or optimizers, we would highly recommend you to make an array map that outlines the precise location of each individual device in the array. You can use the QR codes or stickers to make an array map by sticking them onto a piece of paper. Make sure to plug this array map into your monitoring software during commissioning. This will allow the monitoring software to accurately monitor production while also alerting you to malfunctioning equipment. 

Planning the Electrical Route 

As we have already mentioned, it helps to plan your electrical route beforehand by taking into consideration the type of system that you are looking to install. Make sure to put on the required safety equipment and also try and install the wiring as per the specific instruction given by the wiring diagram. 

PV Sub-panels 

If you are planning to have a system with multiple inverters, you can use an AC sub-panel to combine the AC circuits into a set of single conductors. However, be sure to make note of the fact that dedicated solar sub-panels should not contain any load breakers. 

Roof Electrical Mount 

We always encourage our readers to consider running their wiring through the attic in order to hide it from view if you prefer that scenario. However, take care to ensure that it is accessible and can be connected to the  array, breaker box, panel, meter, and various other parts of the system. Also make sure that you use cable clips in order to secure the wiring of solar panels and micro-inverters/power maximizers. This is important because the clips will provide much needed sturdiness to the wires during strong gusty winds. No amount of exposed wiring should be allowed to make any sort of contact with the surface of the roof. 

Next, you need to run the wiring from the source of solar power to a junction box and then transition it to the conduit run. Ensure that the wiring remains in the conduit until the point that it reaches the inverter (in case of grid-tie systems) or the charge controller ( in case of battery-based systems). You can also use conduit mount flashings in order to secure the rooftop conduit firmly in its place. Furthermore, you can also make use of conduit penetration flashings which perform the task of transitioning the conduit into your attic in order to hide it from general viewing. 

Ground Mount Electrical Route 

The first piece of advice in the case of ground mounted solar panels, is to use dedicated cable clips which can make a massive difference in helping you manage any kind of exposed wiring underneath the array. All of the wires should be well secured against strong winds and also kept away from other equipment so that it does not lead to any difficulties during maintenance. Make sure to consult the wiring diagram so that you know exactly how deep your trench should be and also consult local municipal authorities before digging. Make sure to not drive over any kind of wiring or piping systems while laying cement for your wiring foundation. You should also consult your wiring diagram in order to get a better idea about factors such as type of wiring, voltage fluctuations etc. 

Mounting the Inverter 

The specification of mounting an inverter to work with your solar panels depends on the type of solar power system you are seeking to install. In case of grid-tie systems, inverters can be wall-mounted in indoor spaces or even rigged on the back of any outdoor substructure. In case of off-grid systems, you have to wall mount your inverter. 

In case of wall mounted inverters, those with integrated disconnect switches should be mounted up to a maximum height of 2 meters from the ground. If you are planning to install the inverter in your garage space, make sure to place any kind of ignition source at least 18 inches from the ground for safety. In the case of people who plan to place their inverters outdoors, the inverter should be shielded from direct sunlight and should be placed as far away from sprinklers and or any other water sources as possible. 

For inverters mounted on ground mount substructures, the appliance should be mounted at a height of 36 inches from the ground at the very least. This is because the monsoon season can often produce mud on the ground which could get splashed on the appliance and cause significant issues. It should also be kept away from direct sunlight and the threadlocker on the hardware should secure the inverter bracket so that it supports the substructure adequately. 

Grounding the system 

One of the most essential steps while installing a solar panel system is to ground it properly. This is vital because of a number of reasons, out of which the biggest one is protection from electric shocks. It also acts as a very valuable protective factor in the face of power surges or build of static electricity. Also in the case of a failed or broken circuit, the grounding acts as a safe pathway for fault current to disperse through. 

The metal parts of your electrical system should be bonded to the ground and various conductive metal equipment must be grounded together. This is important as it ensures that all of the equipment in the system has the resistance to the ground. This is called the shared “ground reference”. 

The Equipment Grounding Conductor(EGC) is the green or bare colored copper wire that connects the racking hardware, metal enclosures and the EMT conduit. The Ground Electrode Conductor (GEC) on the other hand is the wire that is used to connect the ground rod to the electrical distribution service. In the case of nearly all AC powered systems, the neutral conductor is equipped with a single bonding point where it is connected to the ground. 

The neutral to ground bonds can be found in generators, breaker distribution panels, power centers, and other equipment.  Make sure that the whole of your system has only one single neutral to ground bond. Something that is essential for every solar panel system is a DC negative to ground bond. Any system that features “ground fault protection” includes the DC negative to ground bond. You also have other integrated grounding solutions which you can consider. 

Backfeed Breaker Installation 

In this section, we will try and give you a step by step breakdown of how to install a backfeed breaker. However if you are not totally comfortable with working on your breaker panel, you can easily go for professional help. A lot of newbie DIY solar panel enthusiasts do the entire setting up of solar panels themselves and outsource the wiring to professionals. However, if you feel like you can take on the challenge then read the following section carefully. 

First important thing to do is to check the proper breaker size you will require. You need to source a breaker that works with your existing panel. We always recommend our readers to use new breakers which are of the same make and model as your existing breakers. Make sure to get rubber mats or a plywood stand to insulate yourself from the ground before you start working. Make sure to shut off the branch circuit breakers one at a time and then shut off the main circuit breaker. Following this you need to remove the panel cover. 

Another vitally important step to remember is to test all of the wires separately with a multimeter in order to ascertain whether there is any leakage of current. Then you need to disconnect the wire of the breaker that you are looking to remove from the load terminal. After this, you need to pull out the old breaker very carefully. And while doing this you should also pay close attention to how it was fixed. You are halfway there by now and the next step is to install the new breaker and fix it into the correct position. Install the new breaker and insert it into the correct position. After this, you need to attach the stripped solar circuit wires to the terminals of the new breaker and torque them into place. 

Now after this is done, there are a few more steps to follow. You need to check all of the terminals through and tighten any possible loose terminals. Also inspect the terminals closely for any other issues. Then you need to replace the panel cover and turn on the main breaker. Following this, turn on the branch breakers one by one and leave the solar for last. Make sure to test the breakers with a multimeter to see if everything works properly not. Then and only then, after carefully executing all of the steps we have mentioned, turn on the solar backfeed breaker. 

Mounting your panels

After you have your wiring and electrical plans firmly in place, the next step is to  mount the solar panels. And in this section, we will tell you how to mount the solar panels effectively to give yourself the best possibility of enjoying a trouble free solar energy system. We will discuss each of the specific mounting options you have at your disposal in the section below. 

Roof Mounting 

If you wish to mount your panels on the roof, you need to make sure that you follow the steps outlined below with as much precision as possible. First you need to locate and mark your roof rafters. After this, you need to install roof attachments so that you can position your rails securely in place. Then you need to install the racking rails. The penultimate step in the case of roof mounting will require you to lift up the panels up to your roof. And finally, provided that all these steps have been carried out properly, you can mount the panels on your rails. We will discuss each of these steps in a little bit more detail in the section below. 

Step 1 : Marking the Roof Rafters ‘’

Roof-mount flashes that are bolted securely to the roof rafters are fundamental to giving you a secure foundation.. One of the easier ways to do this is to use a stud finder. The process is that you need to pass the stud finder over the surface of the rails and it will give you an indication when it has found a stud. You can find these at your local hardware store. 

Another way to do this is to visually look for rafters under the eaves of your roof. In case you are not able to spot them, try and search for nails that are responsible for attaching the fascia board to the ends of the rafters. 

The third way in which you can try to find the roof rafters is to use the powers of Echolocation. You can get a feel of the rafters by walking over the surface of your roof. The rafters tend to feel a bit firm whereas the space between them feels a bit more spongy. There are also rubber mallets which can be used to tap the surface of the roof and get a feel of the rafters. However if you have a roof with sheathing, this method will not be as effective. 

Then there is the process of exploratory drilling which can also be used to find the rafters on your roof. You can start by drilling a small hole on the surface of your roof. If you do not find the rafter straight away, you need to bend a wire to an L-shape and insert it through the hole to search for the rafter. Once you find the rafter upon rotating the wire, you need to carefully measure a distance of 0.75 inches from the edge to the centre of the rafter. Make sure to mark this location so that you can directly drill the lag bolt through the centre of the rafter. 

Step 2 : Installing Roof Attachments 

Once you have effectively marked the location of your roof rafters, installing the roof attachments is the next step. Note that there may be differences in this process with regards to the type of panels and the location of your setup. We have given some common pointers below, which will help you in this process. 

The layout and spacing in between attachments is a good place to start.Ensure that your flashings are spaced in a way that aligns with the mounting holes of your solar panels. It's also recommended to stagger the flashing layout so that it can alternate between the top and bottom rails. Make sure to distribute the flashings evenly across all your roof rafters so that the weight of the array is spread across the whole mounting surface. 

If you are planning to install the attachments on a composite / asphalt shingle roof then follow the steps mentioned here. Make sure to consult the manufacturer’s manuals in order to get the most accurate instructions for installation. You can start by breaking the seal between the shingles using a simple flat bar. Then remove any nails so that you can slide the flashing under the shingle without any issues. The next thing to do is to slide the flashing under the shingle and to tuck the flashing properly into place. Mark the drilling location through the hole in the flashing and fill the hole with roof sealant. 

In case of metal rooftops, most of them use roof clamps that either attach on to a seam or a bolt into the structure in question. There can be many different clamp configurations with each one being slightly different from the other. Make sure to check the clamp manufacturer’s manual for exact details. 

If you happen to have tile hooks on your roof, they can slide under the shingles and fasten to the rafters. A vertical hook will provide you with clearance from the roof tiles. Tile hook installation could require a bit of cutting and grinding of tiles. However, they are widely universal and generally work on most rooftops. 

If you have bought a tile replacement system, you need to remove your older tiles and swap them out for the tile replacement flashing. A lag bolt is generally bolted to the rafters through the replacement of the tiles and this manages to function as a foundation for attaching the rails. 

In the case of ballasted monuts, they do not require you to make any kind of elaborate penetrations on your roof. The weight of the entire system is supported adequately with the help of the racking base and the array. 

Step 3 : Installing Racking Rails 

Once you secure the flashings into place properly, you can move on to installing the racking rails. It's recommended to keep your racking report handy during this process so that you can consult it as often as required. 

Conduct the entire process of measuring and cutting the rails on the ground so that you do not get scraps of metal shavings on your rooftop. Check the distance between the mounting holes at the back of the solar panel frames and ensure that the rails are spaced in a way that matches this distance. You also need to match the flashings with these spacings. 

Use the given hardware to then attach the rails to the flashing. You can use a level to make sure that the rails are evenly positioned. After this, the next step is to tighten the rails with a good quality torque wrench by carefully following the manufacturer’s torque specifications. We would also advise you to attach some form of protective plastic wrapping on your rails to secure it from the threat of insects. Following this, your next step should be to attach the wire management clips and other hardware components to the micro-inverters/optimizers to the rails. Then you need to install the grounding equipment efficiently. 

Step 4 : Getting the panels up on the roof 

We have spoken about the important safety considerations that you should undertake while doing this in our Planning and Safety section so make sure to revisit that if you have any doubts. 

A few other important things that we should mention here is that you should never step on the panels while moving them. Also be careful to have adequate fall protection and wrap your panels in blankets to protect them from bumping into hard surfaces as you are moving them. In terms of the methods you use for lifting, there are a few options at your disposal. 

A ladder lift fitted with a conveyor belt is often used to transport heavy objects up and down the roof. You also have the option of a scissor lift which not only extends upwards but also sideways. The capacity to have horizontal movements makes a big difference as you have to take fewer trips to and for from the roof. Then we have what is called a boom lift. This type of  lift comes with an entire range of movements and also gives you unmatched access to tight spaces. If you have obstacles directly underneath the place where you plan to put the panels on your orrf, this type of a lift will help you to evade obstacles and give you higher leeway for more intricate movements. 

The last method that is still popular despite being somewhat traditional in the case of roof navigation is related to the process of scaffolding. If there are no obstacles in your transporting path, then a scaffolding setup works great and you might not even need any lifts of any kind. The issue with the method is that there are no additional factors which make the process easier, you get the benefits of a solid sturdy foundation. 

Step 5 : Mounting panels 

Once you have all of your panels and the racking put in place, you are ready to install the solar panels and get your solar energy journey started. In this section we will give you a few general tips on how to mount solar panels if you have an IronRidge racking system. Make sure to consult your product manufacturer’s manual to get accurate specifications on how to mount the panels. 

First, you need to place the panels in such a way that the mounting holes are more or less perfectly lined up with the rails. Then you need to use clamps to secure the panels in place. You should also ideally try and torque the clamps with stopper sleeves. Then you need to place the next panel on the rails in order to ensure that the clamps are wedged snugly in between the two consecutive panels. Following this you need to tighten the clamps between the panels. 

Ground Mounting Panels 

If you are looking to ground mount your solar panels, the process is slightly different although the three main steps are more or less the same. First you need to build the foundation to support the entire structure. Then you need to install the racking rails. Finally, you need to mount the panels on your rails. 

Step 1 : Building the Foundation 

Before you start mounting the racking rails, you need to ensure that you have a good solid foundation which can support your solar panel system. Of course, the first thing we would like to remind you of is safety. Handling wet concrete can prove to be tricky for you if you are not accustomed to it, however, you can use protective equipment to ensure the best safety standards. You should definitely have an N95 mask on while working near concrete dust at the very least. 

The first thing to check before diving into your foundation building is to check whether your surface is levelled or not. If it's not then you should consider levelling the grade. You can use either chalk or a string line to mark the outer dimensions of the array and the location of each individual pier on the ground. Make sure to consult your local municipal authorities to know the location of hidden power lines or pipes that are buried underground. Follow the engineering report to know the specification with regard to pier placement recommendations. 

Then we would recommend you to create a temporary lumber structure that will allow you to keep the pipes in place till the time the concrete hardens and solidifies. The pipes must not move in the time it takes for the concrete to take shape as that could compromise and even sabotage the entire structure of the mount. Furthermore, all of the underground pipes should be fully suspended in concrete. This is done to ensure that the pipes do not come in contact with dirt from the ground. 

This leads to a situation known as galvanic corrosion which lowers the stability and sturdiness of the overall structure and is not at all ideal for a secure solar panel setup. Also make sure that everything is set in place before you start mixing the concrete. You need to make all necessary required changes beforehand for best results. Lastly, we would urge you to wait at least for a week before you start laying the pipes and building the rest of the array. Generally, the concrete will take around 21 days to fully cure and during this period we recommend you keep the wooden brace in place. 

Step 2 : Installing Racking Rails 

The second step once you have set up the foundation is to install the racking rails. The racking report should be consulted during this process to get the most accurate specifications regarding rail size and spacing requirements. Make sure that you space the rails in such a way that it matches the distances between the mounting holes found on the back of the solar panels. There are certain ground mount systems which make use of a rail connector bracket that attach the rails to the horizontal support pipes with the help of U-bolts. Lastly, when you are starting a new row make sure to leave some space on both sides to account for the panel overhang. 

Step 3 : Mounting the panels 

The last step left is to actually mount the panels onto the racks. Before embarking on this process, ensure that the racking rails are installed correctly and are housed in a solid, well secured concrete foundation. The first step is to place the panels in such a way that the mounting holes line up perfectly with the rails. Then you need to use clamps to secure the panel perfectly into place. It's better to start with the outside edge of the array. Then you should torque the clamps with the stopper sleeves so that they are wedged comfortably against the outside of the first panel. Then you have to place the next panel on the rails and make sure that the clamps are well secured in between the two panels. Following this, you should tighten the clamps between the panels and repeat this entire process for every single panel in your array. 

Battery Installation 

This is the last big step in the whole process if you are installing an off-grid system (or a grid-tie system with a battery backup). Generally, you will find three different types of batteries used by various solar panel energy systems. These are : 

Each of these three different battery types have somewhat unique installation procedures and separate conditions they need in a battery room. We will go through each of them in detail. We would also remind you to consult your manufacturer’s plans and manuals too to get the best information regarding your own battery setup. We will start off with a few essential safety considerations which are of paramount importance. 

Safety Considerations 

The first and most important point that we would like to make is that you should do everything possible to ensure that your battery never gets short-circuited. This happens when the positive and negative terminals of the battery are connected to each other. This may happen due to incorrect wiring or if any sort of metal object falls onto the battery terminals. It's crucial to do everything possible in order to avoid short circuits. Always be sure to use insulated tools. 

The second safety measure to keep in mind is that you should always remember to remove any type of metallic jewelry before touching the batteries as it could get caught in the wiring terminals. This includes wrist watches as well as rings on your finger. Also be sure to vigilantly remove any long hair and do not wear any sort of loose fitting clothing or material that could get caught up in the wires or  terminals. 

It is crucial to always wear protective gloves as well as safety goggles while working with the batteries. You should also keep a multimeter ready at hand to check the voltage and polarity of various conductors. The next thing to ensure is that all of the wires are secured, stripped or terminated effectively using a torque wrench wherever and whenever necessary. Make sure to route all the wires away from sharp edges to prevent wire damage. 

If you are working with flooded lead-acid batteries then make sure to keep baking soda handy nearby. It is crucial for neutralizing acid spills that may happen due to accidents. Also be sure to wear safety goggles and have an eye-wash kit ready in case the acid somehow gets into your eyes. Be sure to wear nitrile gloves to keep your hands secure. 

Battery Room Design 

You should always try your best to set up your battery bank in an enclosed space to limit the possibilities of any kind of accidental contact with the batteries. Manage your space effectively and ensure that there is enough room for ventilation for the batteries to cool off. In the section below we will give you a few common tips to keep in mind while setting up your battery room in case of different types of battery setups. However you still need to check your manufacturer’s manual thoroughly to get the specific instructions. 

Sealed Lead Acid and Flooded Lead Acid Battery Room Design 

Ideally, you should set up your battery bank in a room where you can control the temperature. Any sort of prolonged exposure to high temperatures will invariably shorten the lifespan of the battery. Your ideal ambient temperature should be somewhere around 25 degree celsius. On the other hand, temperatures that are too low will cause issues for battery capacity so there is a fine balance. 

In the case of sealed lead acid batteries, you need to keep a notepad or writing board in the room to keep track of data during maintenance checks. With this type of batteries, they do not turn off the gas as a part of their routine operations, however they do come with valves which are vulnerable. They might open in case of overcharge or overheating situations. Another thing to keep in mind for this type of battery especially, is to ensure the floor is sturdy and secure to hold the weight of the batteries as they tend to weigh slightly heavier. 

In the case of flooded acid lead batteries, they should always be installed over a spill containment tray in order to avoid spillage issues. Just like the previous one, you should also maintain a log book that can store recorded data. Flooded batteries should also be installed in a thoroughly vetted battery enclosure that has been built with the proper fire and electrical codes. These batteries releasehydrogen gas during the charging process so you should be very careful to not have anything in the room that may ignite the gas. Consider buying a hydrogen monitor too for best possible safety. Also ensure that the floor can hold the batteries in place securely. 

Lithium-Ion Battery Room Design 

For lithium ion batteries, the biggest threat is exposure to extremely low temperatures. The other issue is you cannot charge them below freezing point i.e. zero degree celsius. As a general point of note, you should always check your manufacturer’s manual in order to get the accurate temperature range for recharge and discharge. 

Battery Bank Installation

The method you choose to install the battery bank depends upon the type of battery that you are using and its manufacturer. However, in this section we will go over some of the general points that you should keep in mind while installing the battery bank. 


Sealed Lead Acid Battery 

Sealed batteries provide higher levels of protection as the sealing prevents any kind of gaseous release. However, in situations where the battery gets overheated or overcharged. You should ensure that the battery is not placed near any kind of electrical component or loose electrical wiring. It's also recommended to avoid places which might have some discharge sparks. 

The second important point to keep in mind during installation is ventilation. We have already spoken about this before and it's worth raising the point again. The best way to ensure that batteries are in the right temperature range is to ensure that they remain well ventilated with plenty of access to natural air. Check the ventilation requirements from your local authorities too as you need to be in tune with those as well. We would recommend you to leave at least 1 inch of space on either side of each battery to leave adequate room for air flow and ventilation. 

The battery case which houses the battery should not come in any kind of contact with organic solvents or any kind of remotely adhesive materials. If there is a chance that the batteries might be subjected to any kind of vibration or jerking, ensure that the battery bank is fastened securely. You can also consider placing shock absorbing materials inside the enclosure space itself. 

Another vital thing to keep in mind is that under no circumstances should you or anyone else, knowingly or otherwise attempt to touch the inside of the battery or dismantle the battery itself. Even though sealed lead acid batteries usually do not leak gas, they could end up spilling highly flammable gas if it gets damaged somehow. Any kind of accidental contact with the electrolyte of the battery should be cleaned thoroughly and given medical attention. In case of a small marginal acid spill, you can use baking soda as a neutralizer. 

Sealed acid lead batteries are built to not release gas as a part of their regular operations. However, they do come with vents that are tasked with releasing the internal pressure in case of overcharging. This is known as off-gassing whereby the battery releases built up pressure. Make sure that your room is properly ventilated and the hydrogen level is at less than 1 percent to ensure the best safety standards. You should have good air circulation in the room as some of the larger battery variants make use of the vents to expel gases. Ideally the vent should be at the top of the enclosure because hydrogen gas is light and travels upwards naturally. 

Lithium-ion Battery Installation 

Ensure that the battery case does not come in any kind of contact with organic solvents and adhesives. Leave a min8um of 1 inch of space on either side of the battery to ensure ventilation standards. Other recommendations would be to fasten the battery securely to something if the battery is expected to face turbulence. You should also use shock absorbent material inside the enclosure. Under no conditions should anyone try to dismantle the battery or  touch the insides as these could cause major consequences. 

Battery Wiring 

Once you have completed the setting up of batteries in the right room, the only thing left for you to do is to connect the battery wires. Here again, you should be vigilant and ensure that you follow all of your manufacturer’s instructions while undertaking these procedures. In this section we have tried to give you a few common general recommendations that you can use to smoothly connect your wires to the battery. 

While connecting the wires of the battery bank, the first thing to make sure is that all of the interconnection cables are of the same or relatively same dimensions in terms of size and length. Make sure also that nothing is placed between the battery terminal and the ring terminal of the interconnect cable. The last thing to ensure is that all of the connections are torqued effectively and secured in place. In case you turn on a battery which has some loose or excessively tight connections, the battery terminals might end up melting and you may face other issues as well. 

In case of connecting the wires running from the battery bank to the inverter, you need to keep the battery bank as close as possible to the inverter. Another important thing to keep in mind is that you should have positive and negative cables that are of the same length. The next recommendation is to zip tie the positive and negative cables together for an interval of every 15 inch of cable length. This should also be installed in the same conduit to get the highest possible surge capacity while managing to reduce the electromagnetic interference severely at the same time. The last thing we would like to say is that you should ensure that your cables are routed properly so that they do not interfere with the ventilation of the battery enclosure.

Factors To Be Considered Before Buying The Best Solar Lights For Home

Before you make a decision about which lights to buy, you must take into consideration a few important factors before buying the best solar lights for homes in India. These are incredibly efficient and beneficial devices - so you must have adequate knowledge about them before buying one. 

1. Solar Lights For Garden

Solar lights meant for gardens are usually designed to look aesthetic and stylish, so that they light up your garden in the most beautiful way possible. The lumen level in these garden lights is quite low. Solar lights for gardens are the most popular type of solar lights for outdoor spaces. No matter how dark or late it gets, these solar lights will always light up your garden, to make it look warm and inviting. Different areas of the garden might require different kinds of lighting. 

2. Solar Lights For Security

While solar lights are a great way of providing aesthetic effects to the garden and your home, they are also useful when it comes to security purposes. They can be used to provide light to dark spots in and around your house. You can get these fixed on your front or back porch - and they are usually facilitated by motion sensors, that can sense when anybody is nearby and illuminate the place. 

There is no need for energy charging these security lights - which makes them convenient and easy to maintain. Now any home can upgrade its security system in this pocket-friendly manner. 

3. LED Solar Lights

Another important factor to consider before buying the best solar lights in India, is the fact that you must ensure these are all LED lights. Solar lights, in most cases, are dependent on LED lights for providing bright illumination to a particular place in the home. LED bulbs tend to be more efficient, as compared to the other types of lights because of more diodes and hence, they are mostly coupled with solar power. 

Most manufacturers of solar lights tend to use LED bulbs, since they make the entire system more efficient, eco-friendly as well as pocket-friendly. If there are dark spots in the garden, it is ideal to use LED bulbs for bright illumination. 

4. Hue Or Color Of The Light

As mentioned earlier, LED bulbs are quite commonly used for solar lighting due to various reasons. LED bulbs tend to emit a bright, white light, that is great for illuminating dark spots. However, you might be interested in different hues as well, to make it look more aesthetic. For this purpose, incandescent bulbs are available in the market. These also come with tinted covers, like amber or soft white. Having a variety of color lights in the house, makes it easy to change the lighting as per the occasion. 

5. Budget

The last, but equally crucial factor that needs to be considered before getting a solar home lighting system, is your budget. There are a variety of solar lights available in the market today, as more and more companies are manufacturing these.

They fall under varying price ranges, depending on quality, performance, and other factors. The larger the bulbs are, and the more photovoltaic cells are present in them, signify more highly-priced solar lights. 

This simply translates to the fact that the brighter the lights are, the more expensive they are. You must fix a budget for yourself before venturing out into the market. This will help to narrow down the options and buy the product that meets your requirements. 

6. Disadvantages Of Solar Lights

While solar lights are very useful and efficient elements, they come with a few cons that are important to mention. They might be slightly more expensive than the standard lighting systems, especially the high-quality ones. However, there are hardly any maintenance costs, and these lights tend to be more durable - so the long-term expenditure is not so much. 

Solar lights tend to be less bright as compared to standard lights. Yet another drawback is that the lights are completely dependent on solar energy, and the batteries can store energy only on sunny days. This constant dependence on the weather makes these lights vulnerable. Keeping in mind these limitations, we give a big thumbs-up to solar lighting systems. 


We hope that this article will provide you with the support and guidance that you are looking for in buying the best solar lights in India. With the plethora of solar lights available in the market today, choosing anyone can be quite a challenging task, and hence, you must do adequate research before finalizing an option. 

Life in the 21st century is, in many ways, dictated by the limitations and possibilities of technology. It is quite impossible for us now to even dream of living in a world where electronic gadgets and electrical appliances are not commonplace.

And with the demand for electronic gadgets increasing, we also have a subsequent growing demand for power and charging equipment. This is where a power bank comes in. This device has over time, become one of the most sought-after gadgets globally. 

In this article today, we will discuss the topic of solar power banks, as we try and encourage people to go green and take the eco-friendly route. Just like electric power banks store power through electric energy, solar power banks do the same with solar energy.

Factors to Consider while buying a solar power bank 

Solar power banks can be incredibly useful if you plan to go on long trips where you do not expect to have access to electricity. It will be enough for you to charge your phone or other USB devices up to 3 to 4 times per day. In this section of our solar power bank review, we will discuss some of these factors in detail. Make sure to go through this section carefully, before deciding on which particular solar power bank model to buy. 

1. Wattage or Charge capacity 

Not all solar power banks are the same, and some are more powerful than others. This means that the wattage of any particular solar power bank determines the type of devices that you will be able to charge. A simple old school smartphone can be charged using the most basic solar power bank, which has a wattage rating as low as 4-5 watts. However, some of the more recent higher-end smartphone models might require higher wattage. 

A lot of iPhone models are known to be a lot more power-hungry and would require a power bank of a minimum 7-watt rating at the very least. In the case of iPads, we would recommend a 15-watt power bank, and laptops would require you to have a battery and DC-to-AC inverter. Also, make sure to note that some of the lower wattage power banks require a lot of time to charge devices, and this could prove to be an issue. 

2. Output Power and Geographical/Climate Conditions 

Make sure to note that in places where the weather is predominantly rainy or cloudy, it might prove to be slightly more difficult for you to charge your device. In these scenarios, you have to make sure to make the most optimum usage of the time when the sun is out and shining bright. Also while checking the output power on your device, make sure to check whether it's for one port, or for all the ports taken together. 

3. Connection or Port Type 

Most of the solar power banks nowadays come with a standard USB 2.0 port, that can be used to charge a plethora of different electronic devices. However, there are quite a few devices that might require a separate adapter to charge them. This is the case for laptops, as well as some other devices, such as photo cameras. Make sure to note the fact that most devices that use a 12-volt cigarette type charging port, generally do not work with solar power banks. 

4. Convenience 

Whenever you buy any type of electronic equipment, the convenience of usage should be right up there as one of the most crucial factors that you use to determine the overall value and feasibility of the product you are looking to purchase. Under this section, you should look at factors such as size, compactness, weight, etc., and determine whether it conforms to your own usage expectations. 

Also, it's important to go for a model that is easy to install and use on a regular basis, if you are buying your first solar power bank. Furthermore, you should consider a few other elements such as special grommets, which may help you to attach panels to your backpack if you wish to have a more sophisticated overall experience. 

Another thing that a lot of people ignore or do not pay enough attention to, is the weight of the power bank that you are looking to buy. If you are one of those backpackers who like to go on long trips and enjoy the solitude of the wilderness, weight is a very important factor to keep in mind. On the other hand, if you do not expect to carry your device for too long outdoors, then the weight factor is not that critical. 

Frequently Asked Questions 

Q1. What are the best ways of using solar power banks? 

Solar power banks are just like normal power banks in many ways. The only point of difference is that they are equipped with solar panels, which can use sunlight to charge themselves. So you can use solar power banks just like normal power banks if you wish.

However, the best use of solar power banks is possible when you go for outdoor trips, and you do not have access to electricity for long periods. How you use your solar power bank is largely up to you, but it can be a real lifesaver in outdoor situations - so it's something that everyone should aspire to carry. 

Q2. How can I fully charge my solar power bank? 

Just like any other solar powered device, solar power banks are equipped with solar panels of particular wattages, which are able to use the sunlight to power itself. You need to simply expose your solar power bank to direct sunlight for a specific amount of time to charge it fully.

It's difficult to put an exact number on how long it takes for sunlight to charge your power bank -  as it depends on various factors, such as wattage of panels, intensity of sunlight, temperature, etc. Some solar power banks also come with separate chargers and adapters, which can be plugged into wall sockets and charged comparatively quickly. Make sure to check the brand and specs to get an accurate idea of these aspects. 


In this article today, we have tried to find the best solar power bank brand for your charging requirements on the go.

There are no moving parts in solar panels, which is why there is not a whole lot of maintenance to take care of. Cleaning, however, is one part of the maintenance of solar panels that should not be taken lightly. Let’s understand through this article about the necessary tips on cleaning the solar panels effectively.

Although solar panels might appear to be sensitive, fragile in nature but unlike their appearances, they are immune to bear all weather conditions and are durable with less maintenance requirement. It’s usually advised by manufacturers to keep the panels clean, dust-free and to avoid the accumulation of leaves and impurities but in reality, all these concerns can naturally be taken care of by rain. A simple recommendation would be adding manual cleaning and maintenance of the panels besides the rain to ensure the functioning of the solar panels with the maximum potential.  


When do you decide it is time to clean your panels?

You can decide whenever if there's even a need to start the cleaning. You have to manually check the solar panels to see if there is any dirt, bird droppings, waste, etc. But you can do that too if you have a monitoring system that will warn you if your panels are not running and working well enough. You should know, however, that the alarm might point to some mechanical or electrical issues, not just the need for cleaning.

A piece of advice that is usually passed around, is to let the rain take care of the cleaning of your solar panels. Track the functionality of your device by paying attention to your month-to-month energy bills and use. Perhaps it's time to think about cleaning or some other form of maintenance if you start to see changes in your energy bill.


What precautions should you take before starting the clean-up?

In the sunlight, solar panels can become extremely hot due to their heat absorption abilities. Either clean your solar panels during the morning/afternoon, or select a reasonably cool day. Also, see if there is some possibility to do this without having to climb up to the panels. 

Keep your ladders ready if it is required for you to climb up the roof and be prepared with all the necessary equipment and proper training to not cause any fatal injuries.You can always consider calling a professional cleaner to clean the solar panels to be on the safer side. 


What can you use to clean up?

Checking with your solar panel manufacturer is the first thing you want to do. They may have unique cleaning recommendations.

The basics are water and soap, and a hose - that makes the whole thing so much simpler. Keep in mind that when washing off your solar panels, you should not use any form of high-pressure water sprayer. Water quality is also something that should be noted. If the water supplied is hard (mineral-rich) and rainwater is available, use that as a final rinse to avoid deposits from hard water.

The solar panels themselves can be affected by a high-pressure connection. Sponges are excellent tools with which to clean solar panels, because they will not cause any damage. Use something you would clean your dishes with, if you plan to use a little bit of soap on your sponge.

However, if you have collected a lot of dust and dirt, you might need to give them a more thorough cleaning. You can turn on the water at the beginning and wash the panels with a garden hose. And you will see if any dirt is still left. You don't have to disinfect the underlying wiring. They are strictly prohibited - because they can only do harm. Do not use any chemicals and abrasive materials.

Bird droppings are more harmful than a film of dust on your solar power panels. One point to check is whether a string or micro inverter is a part of your system. This is critical, because systems with microinverters (with an inverter attached to each separate panel) will display where one component has been covered with droppings. The inverter will avoid displaying current flow during these instances.

In some cases, the panels can get oily stains on their surfaces if they are located in areas which are near to airports, flight paths or are subjected to prominent roads frequented by trucks. In this case, you may prefer to use isopropyl alcohol as a spot cleaning chemical, which is also found in daily household items as aftershave lotions, sanitiser, etc. 


What do the experts say about cleaning solar panels?

It seems that experts cannot come to a consensus on this one. One side claims that this initiative will not pay off if you plan to recruit professionals. They argue that dirty solar panels can operate with just five percent less power, which is negligible. This hypothesis is based on the fact that solar panels are still impeded by these small particles, and that they have not been found to work at a reduced capacity. As the solar panels are tilted at an angle for making the solar panels effective in receiving maximum solar heat, the tilt usually allows the dirt to settle down at the bottom of the construction. 

Some believe that the solar panel system will lose 15 to 20 percent of their strength, if the solar panels are not cleaned properly which will eventually cause less electricity generation. 

A landmark experiment was performed by Google at their 1.6 MW solar farm in Mountain View, California. They found that the number one way to optimise the energy they generate was to clean the solar panels. Cleaning solar panels that had been in service for 15 months doubled their electricity production.

Experts are leaning towards ‘no’ for cleaning solar panels in spite of a lot of research, and particularly if you want to hire a professional company instead of cleaning them on your own, the return on this type of investment is way less than what you are putting in.

The best possible advice when it comes to this subject, is to track your solar energy system, to see if and when the power output changes. If you think changes in your energy bill might be because you need to clean the solar panel, see if after a good rain, the quality returns to normal. If so, that's the end of it, perhaps. If you think the functionality is still askew, instead of just washing, it may be something electrical that needs repairing.

It also depends on where you live. If you live in an area where it snows, you will have to manually shake off all the snow from the panels.  During the winter, solar panels usually become the most soiled. When it is time for leaves to shed in autumn, you can certainly strip leaves from the panels. 

 All those who think solar panel cleaning makes a difference, are advised to take some time to do the job once or twice a year. This should continuously hold solar panels at their full capacity.

But you can do this more frequently if your house is located close to a highway, airport, plant, or some other source of pollution. Your solar energy system would be subjected to more debris collection.

It's important for you to at least periodically rinse off your panels, depending on your weather conditions, dust, and other pollutants that may collect on your solar panels. Engage in safe cleaning practises and avail professional help if you deem it necessary. The solar panel company would also be able to decide if cleaning is necessary and when to do it along with tips on how to carry the operation out. Carry out a thorough visual inspection and assessment before the cleanup. This would help in upkeep and maintenance while helping you save energy costs.  

Solar panels are an efficient roof addition that help minimise energy costs and benefit the environment as well. Solar panels are based on solar cells that absorb sunlight, and convert it into renewable energy. Here, we explore how the weather affects a solar panel’s efficiency.


Every manufacturer says that positioning the solar panel in a way that will ensure that it is always exposed to the sun, is extremely important. That is rational, since in order to do its job, it requires as much sunlight as possible. So what happens one day when there is no sun? What if the rain has overtaken the sky?


The response is that nothing occurs. Solar panels will continue to transform photons into electrons, or direct electricity. There's a huge misunderstanding, that if there is no direct sunlight, the solar energy system won't be able to produce the power we need. In fact, solar panel cells do not actually need direct sunlight, they just need certain sun-emitted photons.
The impact of the weather on solar panels is a common concern among first-time solar buyers. Despite rain, snow, sleet and hail, a good-quality solar panel will work to the best of its capacity. 

Modern-day solar panels are designed in such a way that they can withstand various weather conditions, such as heavy rain, snowstorm, hail, severe wind, and extreme heat. When they are built, they are subject to testing, and in order to say that they are immune to bad weather and extremes in that sense, they need to get a TUV Rheinland Certificate in India. 


In fact, most solar panels can withstand winds of up to 140 mph, which is around 2,400 pascals (the unit in which solar panel wind resistance is measured). This is strong enough to withstand a hurricane of Category 4, whose wind speeds range from 130 to 156 mph. They can also only benefit from cold temperatures, because light can reflect the whiteness of the snow and boost the efficiency of the panels. It is just important that they are clean, and not settled on by tonnes of snow.


Since they are made to last and face multiple obstacles, solar panels can for example, be damaged by hail or storm. But you should be protected by your warranty or insurance policy in that situation. The effectiveness of solar panels, however, can diminish in extreme hot climates.


Let us look at different conditions:

1. Night

Now in order to work, solar panels require sunlight. When the night arrives, they appear to go into sleep mode, and remain that way until the sun starts to rise again. However, some experts say that solar panels will operate on the basis of some other light sources, such as the moon, or some powerful street lights, but since the production would be extremely low, it is negligible.


2. Rain

In order to produce electricity, solar panels are designed in a way that enables them to use direct and indirect sunlight. This means that even if the sun is obscured by clouds, they will be able to continue with this process. So yes, they can work in the rain - the question is just how much power can they produce. Rain will not have a negative effect on solar energy production, but dense layers of dirt will, considerably.


Therefore, the rainy season requires occasional cleaning of your panels, to get rid of dirt and other things that reduce sun exposure. 


4. Snow 

Accumulated snow will block light from your panels, just like dirt. In most cases, this is rarely an issue, as snow falls off panels easily, and tends to melt in the sun rapidly. If snow does accumulate on your panels, sweeping it off with a broom won't hurt. The whiteness of the snow would reflect light and boost the efficiency of the solar panels. 


Colder temperatures usually improve the effectiveness of the panel. Subfreezing temperatures, and sunny weather are perfect for solar system installation.

5. Hurricane

This natural force will cause some serious harm to your whole house, not just the solar energy system. The power of the wind might dislocate your solar panels, separate them from the roof and rip some wires, but most likely, the insurance will cover that. Solar panels are built to withstand winds of about 140 mph, but in general, every brand has its own, more unique assessments. 


6. Lightning 

Solar panels, like any other electronic system, are subject to voltage spikes due to lightning. The odds of lightning hitting your roof on its own are slim. Even in such a case, a danger that may occur is transient voltage. A professional installer, however, can make sure that the device is adequately grounded to stop surges. A lightning protection system is a clever and simple upgrade, if you want extra surge protection. 


7. High temperatures

Many people believe that unlike rain and clouds, high temperatures are highly advantageous for panel efficiency. It really seems contradictory to assert that high temperatures reduce production. 

Higher temperatures however, do tend to lower the output of electricity, also known as the drop in voltage. Power is generated by voltage and current, and high temperatures tend to increase the current. However, they also have a decreasing influence on electrons. Increasing temperature therefore means raising the electrons' remaining state, which results in lower voltage, and is equivalent to lower performance. 

If you live in warm places, however, this doesn't mean your panels aren't successful. Ultimately results will level out, and the panels will produce the savings.


8. Hail

It is a fair subject to be concerned about, given that hail could hit your panels. Hail can represent the most physically intense of all natural conditions. The most important aspect when it comes to the damage that hail causes, is the nature of your solar panels and their installation. Most panels are made to withstand harsh hail, however. Try to invest in high-quality solar panels that are sturdy enough to prevent damage caused by hail storms.


9. Cloud cover

Panel functionality would be affected by anything that blocks the sun's rays, like clouds, fog, mist and smog. The impact of different cloud types on the output of panels at noon, ranges from almost no loss for wispy cirrus clouds, to 30 percent or less than ideal for traditional dark rain clouds.

Although 30 percent might sound like a lot, remember that at 70 percent the panel is still producing energy, and that even cloudy places get sunny days. For example, Germany is a place which has a lot of cloud cover all round the year, but is still one of the top places with maximum solar system installations. 



In severe weather conditions, even though solar panels look very fragile and super sensitive, they are actually used as roof protectors. There are some potential hazards to your solar panels' performance and stability. Advanced technologies and skilled contractors, however, help you still plan ahead. Panels are designed to endure extreme weather conditions today. Combined with proper installation, and quality manufacturing, it will ensure you have zero problems with your solar panels' performance. 

Once you have zeroed on an installation company, make sure that they have all the licensing as well as registrations. The company should be reputable and known for their work. Not all of them know what modern solar systems technologies are based on, or they are not well informed about local wind movements and other climate conditions that are normal or exceptional. Also it is necessary to consider the regulations that are  to be taken into account when carrying out a task like this. This needs to be kept in mind with the right angle that is required when one has to position a solar system to ensure maximum capacity is delivered. The advanced wiring systems they require can be a challenge for certain individuals. 

It is important to check if the house's roof is suitable and sturdy enough to hold the entire solar energy system.

The fact that solar panels function with the help of sunlight, raises the problem of bad weather and its effect on the solar energy system. We concluded that on a cloudy day, panels will still continue to turn the sun's power into electricity. This too, however, has its flaws, just as with any other renewable source and its use. But the truth is that the benefits are so fantastic, that you can certainly live with that. Since your solar panel can generate more energy than you need on those super sunny days, all that surplus can be stored and saved for days when they simply can't deliver.

A solar plant produces clean, renewable energy throughout the year in any weather condition. It is a healthy investment, and helps to cut back on energy costs, and generate power for the entire house in a sustainable way. 


With greater dissemination of knowledge about the conditions of our natural world, more and more people are moving towards renewable sources of energy. Solar energy is one of the major forms of renewable energy in use today, and a lot of people, as well as businesses are making a conscious decision to invest in this technology and reap the benefits in the longer term. In this article, we will direct our focus on the specific question of solar panel compatibility, and what are the various elements that will ultimately help you determine the best combinations. This will allow you to get optimum levels of performance from the investment you make on your solar panel system as a whole. 


Solar panels come in different varieties, and it is important to know which ones are best suited for your power requirements. One of the measures which is used to differentiate between different panels, are the respective wattages of the panels themselves. There has been a lot of misinformation and partial information surrounding the topic of wiring different solar panels. It is important to recognize that it's not as simple, as more panels equals higher power. There are different factors that you need to take into consideration while making a judgment. 


In this article, we will look at some of the things you should keep in mind if you are looking to mix different panels. 

Basics of Connecting Photovoltaic Panels 

We should mention at the start, that mixing panels are not recommended in general. However, if you make sure to carefully mind the parameters of those panels, like wattage, voltage, amps etc., it is possible, and you can derive good results from it. There are two main ways in which you can do this. These methods are called series and mixed modes of connecting solar panels. The best method to connect your solar panels is in turn, determined by 3 different factors. These are: 

  1. Type of solar panels used 
  2. Amount of solar power you wish to generate 
  3. Other parameters such as charge controller, battery and inverter specifics


Series or Parallel or Mixed 

There is a lot of mystique and misinformation related to the question of which method to use in order to mix different panels. This depends upon your requirements essentially, and there are pros and cons with each. If you are looking to get a higher voltage, then it would be best for you to go for a series connection. Similarly on the other hand, if you wish to get more current as opposed to higher voltage, then you should go for a parallel connection. And of course, if you need both higher current as well as higher wattage, you need a mix of both series and parallel connections. 


Whether it be in series or parallel or mixed connections, you should definitely consider adding solar panels, if your existing panels are not getting the job done. This is because, irrespective of which type of connection you choose, more panels will give you a higher total wattage count regardless. 


As we have mentioned earlier already, there are 3 different kinds of wiring possibilities that solar panel users have at their disposal, when it comes to connecting panels of different wattages. We will discuss each of these in the section below in a little bit more detail. 


Solar Panels Connected in Series 

As mentioned already, a series connection gives you the prospect of generating higher voltage along with a higher watt count. Series connections are mostly used in grid-type tier systems, as they require higher voltage in order to function at optimum capacity. These types of grid systems are generally equipped with higher voltage panels. Generally, we have found from our surveys that the system voltage for these types of systems are at least 24 volts. Another point of note about this system that we have encountered, is that the solar array output voltage is connected to an inverter or a charge battery. This charge battery is also usually powered by a comparatively higher voltage than we find in most non-grid systems. 


A series connection basically means that you are connecting the positive terminal of a panel to the negative terminal of the next panel. In case of this connection, you will get a total output voltage that is the sum of the voltage drops on each solar panel, provided that the panels are of the same type and also the same power rating. 


If the panels that you will be using are not of the same ratings, then the question becomes somewhat more complicated. The current produced from a solar panel is dependent on a combination of factors such as ambient temperature, solar cells temperature, and solar irradiance. This leads to a situation where if for instance, you are using panels of different wattage and one of the panels has a much lower current, then this will end up dragging down the performance of the whole solar array. This is a situation that you should ideally avoid, if you wish to get the most out of your solar panels. 


Wiring Solar PV Panels in Parallel 

Parallel connections are one of the simplest methods of connecting solar panels, along with series, and it can also be effective for you if you’re looking to do these things with a DIY spirit. This type of connection is best suited when and if you are looking to increase the total output of the array, while keeping the voltage rating unchanged. The voltage is usually static,  based upon the 6v or 12v panels that you are using, in the case of off-grid systems. 


This type features a connection between all of the positive panels with each and the negative panels with each other respectively. Eventually, it all boils down to one positive and one negative connector - which are finally connected to the inverter or the charge controller. A parallel connection enables you to have a total output current that is equal to the sum of all the different current ratings passing through the various solar panels. If the panels are of the same type and the same ratings, this process will be seamless. 


Again, if the panels are of different ratings, then the story is somewhat different. In this case, you will end up losing a lot of your solar power - which could have been used to give you additional current capacity. This is because the array’s total voltage depends on the lowest voltage rating, which causes the complication. 


Mixed Wiring of Solar Panels That Includes Both Series and Parallel

Mixed wiring of panels basically means that you are using a combination of two different panel connecting systems to bring about your final energy output. How effective this will be, is largely dependent on your total output voltage, and the maximum total current output of the entire solar array. 


In order to be able to do this correctly, you need to keep two things in mind at all times without failure, which will serve as your base point of entry. These two things are that series connections manage to increase voltage, and parallel connections manage to increase current. Both however, result in increased wattage. However, the wattage will go down if you choose to use different rated solar panels. 


The best way to ensure the most optimum levels of performance from your solar panels, while using a mixed wiring system, is to make sure that your solar array is composed of an even number of panels. This means that you have to have panels in the multiples of 2 such as 4, 6, 8 and so on and so forth. These panels could be put in various types of wiring combinations. For instance, if you have 4 panels, then you can put 2 in series and 2 in parallel. 


All this is good to talk about in theory, however in the case of practical implementation, it is very much possible that you might find yourself in a situation where you have an odd number of panels as part of your solar array setup. In this case, you should reconsider this type of mixed wiring, and consider the advantages of series or simple parallel wiring systems. If you have a preference for differently rated panels instead of having to buy similar rated ones, it is best to separate the panels in two different sets, and wire them in parallel. 

Summarizing points 

In this section, we will mention some of the important points that could be observed in summary of the above detailed discussions that we have already had. 

If you decide to go for a series connection, it is more important to ensure that the rating of the different panels is always the same. On the other hand, if you decide to go for a parallel connection, then we would urge you to make sure that the voltage rating of the different panels are the same. 

If you mix different types of panels, inevitably, this will result in overall reduced wattages. This happens regardless of whether you end up using a series connection, or parallel connection mechanism. 

If you add even a single panel which has a lower rating then the other ones, it will result in lowering of the entire power output. A lower rating basically means that it has a higher potential for loss of solar power.  This happens for both the cases of series and well as parallel connections. However, the loss of solar power is more severe in the case of a parallel wiring system. Thus, it is best advisable for you to try and get panels with the same ratings if you harbour aspirations of churning out the maximum possible power from the panels.  


Final Recommendations 

In this section, we will have a recap of some of the major themes and highlighting points of our discussion above.  We will start off by telling you something that we have revisited quite a few times throughout the course of this discussion, and that is because it is of vital importance. We would urge you to try and get panels with similar ratings - regardless of the type of wiring system you are looking to set up. 


Try and minimize losses, while connecting solar panels by following these guidelines mentioned below. 


If you are looking to connect solar panels of different brands, make sure to connect it in series panels. If you are looking to connect panels of the same brand, but of different voltages, then make sure to use a parallel wiring system to connect the panels. 


We also do not recommend that you connect different solar panels in a particular solar array. This is because, if you choose to do so, either the voltage or the current output might get reduced, and this will not allow you to extract the optimum amount of performance from your solar panel system. 



In this article today, we have tried to give you some important and valuable information regarding the setting up of solar panels. A lot of people have been making the transition of late to using renewable and sustainable forms of energy. This brings a lot of questions to their minds, and one of the major questions that usually dominates discussions on online forums, relates to the topic of wiring different panels together. It's just not as simple, as more panels equals higher power or vice versa. There are a lot of nuances involved in this, and we have tried to cover these as much as we could, without over burdening you with too much technical detail. 

We have also made it a point to summarize some of our core recommendations and try to bring it to your attention. This will enable you to make a more informed choice that is based on evidence and suitability factors. We hope that the information you found here comes in good use for your purposes, and you can build the ideal solar power system of your dreams. Make sure to note that the information you find here merely touches upon the surface - and if you feel the need to know more, you can do further in depth research.

Factors to look for while buying a solar water heater

1. The source of water

The very first thing to look for while buying a solar water heater is the source of water supply in your house. It is important to determine whether the water that you receive is hard water or soft water.

This is because each of these types of water has different mineral capacities and thus, requires a different heating system. There are two kinds of heating systems: direct heating and indirect heating. 

The direct water heating system is suitable for soft water sources. However, in the case of hard water, it is advisable to go for an indirect water heating system. Both direct and indirect solar water heaters are available in the market. In a direct water heating system, the water is heated directly through the heat of the sunlight trapped by the solar water heater.

However, in an indirect system, a fluid is used. The fluid is heated by the solar panel, which in turn, heats the water used in the house. This happens through a system of heat exchange. This is necessary because heating the hard water directly can result in pipe blockage. It can also corrode the collector tubes, and thus, affecting the functionality and longevity of the solar water heater. 

2. Type and Functionality

There are mainly two different types of solar collectors - Flat Plate Collectors (FPC) and Evacuated Tube Collectors (ETC). The FPCs are made out of metals like copper or aluminium. This type of water heaters are particularly suited for tropical climates, as they have a higher degree of conductivity and emissivity.

This is why they are poor heat retainers under low ambient temperatures, and are hence, not suitable for temperate regions. In general, FPC water heating systems are bulkier than ETC systems. However, they are robust and more durable. They are also easily serviceable. 

The ETC water heaters, however, have a higher heat retention capacity. Thus, they are suitable for both tropical and temperate regions. At the same time, they are made out of glass. Therefore, they are quite delicate and must be handled with extreme caution during installation, service, and operation. 

Both these technologies can be used in open and closed-loop systems. An open-loop system works well for areas with clean and soft water, as the chances of clogging and scaling of the tubes which circulate the water are less. On the other hand, a closed-loop system is well-suited for areas where one does not know whether the type of water is hard or soft, or one is not aware of the cleanliness of the water.

It uses a difficult heating medium from the water in circulation. The heating medium is not allowed to be mixed with the water being heated. An open-loop system, on the other hand, uses the same circulation water as the heating medium.

Besides, water heaters can also be classified as hybrid and nonhybrid. Hybrid systems are equipped with an additional electric heating system in the storage tank to provide heating when solar energy is not strong enough to heat water. The non-hybrid systems, on the other hand, do not feature any such technology. 

3. Size/Capacity

The size of the solar water heating system is another important factor that you must be aware of while buying one for your home. The capacity of solar water heaters is indicated by LPD, which stands for liters per day. On average, a person uses some 30 liters of water. Hence, a 100 LPD solar water heater will be ideal for a family of 3.

In smaller homes, solar water heaters with a capacity ranging between 150 and 200 liters are sufficient. However, a larger household might require a 300 LPD solar water heater. On the other hand, commercial and industrial sites require solar water heaters in the range of 500 LPD to 5000 LPD. Most of the best solar water heaters in India which we have reviewed in this article have capacities ranging between 100 and 500 LPD, are most suitable for homes and small commercial installations. 

4. Plumbing Work

Installation is one of the important aspects of any solar water heater. Wrong plumbing work can render the entire machine dysfunctional. A number of plumbers are not simply aware of the working of the two-piping mechanism. In this mechanism, hot and cold water is connected to the house using two pipes, one for hot water and the other for cold water. It is mostly used in bathrooms. Moreover, it is essential to use the tube type of solar heater as it heats the water at a much faster rate, and is economical when compared to the flat type. 

5. Type of Tank

Tanks act as storage sites for the heated water. They should be able to withstand the heat and retain the same. A thick, well-designed tank can retain heat for more than 60 hours. Besides, the tank should be made of a food safety grade material to ensure that the water stored does not give out a foul smell. 

Besides, tanks should also be rust free. Tanks with enamel coating are the best to prevent corrosion which is caused by hard water. You must always check for the material used for the tank in the product description. 

6. Service Life

It is important to be aware of the service life of solar water heaters. Similarly, it is also important to know if the brand can provide after-sales service at your location. Besides, you also need to be aware of the warranty offered by the brand on the product. Some of the best solar heaters for homes come with a warranty period of 5 years. 

A good solar water heater can last for more than 15 years, given that you maintain it well, and go for servicing from time to time. While buying a water heater, you need to maintain price and quality. Always take a closer look at the product description before buying.

7. Water Pressure System 

It is very important to consider the water pressure in the house. A lot of times, one ends up buying a water heating system that cannot withstand the pressure coming from the water source. Such a water heater has a high likelihood of being damaged. 

There are two types of water pressure systems - the pressurized and the non-pressurized system. Equilibrium needs to be there between the supply line and the solar water heater. Selecting the wrong application for the wrong system will lead to an obvious failure of the system.

In addition, you need to check whether the solar water heating system is going to be placed on a pitched roof, or a flat environment. Each of these requires a different kind of system for producing optimum results. 

As a general rule, it is always suitable to buy a solar water heater that can withstand a greater degree of water pressure. Solar water heaters that can withstand 8-10 Kpa of pressure are the most ideal. They must also come with a faster heat recovery mechanism and an efficient heat exchange technology.

8. Temperature Regulation 

Solar water heaters must be equipped with an inbuilt thermostat capacity which can maintain a water temperature between 60 and 75 degrees celsius. This is to avoid scalding effects, such as skin burn from hot water. The burn is dangerous as it can destroy tissues and cells, and in extreme cases, it can cause the body to go in shock from the heat.  

9. Climate and Geographical Location 

It is important to know about your climatic/weather conditions before purchasing a solar water heater. Since a solar water heater draws heating energy entirely from sunlight, therefore, your location should get enough sunshine, particularly between 10 am and 4 pm on a daily basis. Direct solar heaters are feasible in tropical areas, as they receive the maximum sunshine. However, in temperate regions, it is better to buy a hybrid solar heater, because of the limited sunshine hours. 

10. Professional Installation

As already noted, installation is one of the key aspects of any solar water heater. Therefore, it is important to buy solar water heaters from reputable companies, as they offer professional installation. The same holds true for after-sales services, as well. You should be able to get quick and timely responses from the end of the company.

A good installation ensures that the device works as it should and it also adds to its longevity. The basic steps in the process of installing a solar water heater include mounting the solar collectors on the roof or the ground, followed by the installation of the storage tank and the heat exchanger next to the water heater.

Other steps include installing the piping and pump for the glycol loop. Besides, the pipings and other controls should be perfectly installed for the best performance. 

11. Maintenance 

Periodic maintenance is very important to ensure the efficient operation of the solar water heater. Apart from the heating system itself, you must also keep the pipes of the house well maintained. In addition, maintenance of water valves are equally important, so as to ensure an optimum level of water pressure. You should definitely hire a good plumber and ensure that the technician involved in the maintenance of the solar water heater is skillful enough to handle everything properly. 

Frequently Asked Questions

Q1. Do solar water heaters work on cloudy days?

The main requirement for the working of solar water is sunlight. Therefore, for optimum heating, you will need sunny conditions. The heating output is directly proportional to the amount of sunlight available at a particular moment.
Under bright overcast conditions, a solar water heater can generate 50 to 70 percent of its typical output. However, on rainy days, or under cloudy conditions, the use of an auxiliary backup will be required. 

Q2. Do solar water heaters work in winter?

There are a number of factors that decide the overall output of a solar water heater. If the system is equipped with good insulation, sunlight will be able to heat the water quite well, even during the winters. Since the heating is done by the radiation energy of the sun, it can come through the glass and heat enclosure.

This means that even if the temperature outside is below freezing if there is good insulation, there will be minimal heat loss. Besides, the other thing is how good the tank’s heat retention capacity is. A good quality tank can retain the heat for a long time, even under low outside temperature.

Q3. Does a solar water heater work at night?

A solar water heater cannot generate hot water during the night. However, the hot water which is generated during the day is stored inside the storage tank. A tank that is equipped with good PUF insulation can store hot water for more than 24 hours. Thus, you can enjoy a good shower under hot water even at night. 

Q4. How much energy/electricity does a solar water heater save?

A solar water heater is one of the most cost-effective water heating solutions for any house. A 150 LPD capacity solar water heater, suitable for 3 to 4 people, can result in savings of up to 1500 units of electricity every year. Thus, solar water heaters also result in the reduction of carbon footprints.

Q5. How long do solar hot water systems last?

It entirely depends on the quality of the solar water heater. Other factors include the quality of the water, maintenance, etc. In general, a good solar water heater can last for around 15 to 20 years, depending on the material used to protect the inner tank of the water heating system.

A solar water heater with a glass-lined coated tank can last for well over 25 years. The best solar water heaters in India, which we have reviewed in this article are extremely durable and can easily last for more than 15 years. 

Q6. What is the ideal capacity for a solar water heater?

The thumb rule in deciding the capacity is that a person requires 30-50 litres of water. Also, note that the water heater should be installed just above the bathroom floor. The following chart can help you in deciding the capacity of a solar water heater that you would need for your household.

100 LPD2 to 3 persons
150 LPD3 to 4 persons
200 LPD4 to 5 persons
250 LPD5 to 6 persons
300 LPD6 to 8 persons
500 LPD10 to 14 people


Solar water heaters are extremely efficient gadgets for delivering hot water to your house. The best thing about solar water heaters is that it consumes no electricity. These are environmentally friendly products and aid in the reduction of carbon footprints.

However, buying a solar water heater is more difficult than buying a regular geyser. This is not just because of the exceedingly large number of brands and products, but also there are a number of factors, specs, and features that one needs to look for. 

Therefore, in this article, we have tried to help you buy the ideal solar water heater for your house. We have included all the important factors that you need to look for while buying a solar water heater.

Besides, we have also listed down and reviewed some of the best solar water heaters in India. We have also answered some of the frequently asked questions with regards to these products. Go through our buyers’ guide carefully, and make an informed decision. 


People globally have started realizing the true worth of solar energy, and how valuable it is when it comes to protecting the environment. Solar panels and solar inverters are not only affordable, but also dependable and financially quite advantageous. While most people are aware of the environmental benefits of a solar system, its financial benefits are lesser-known. 


There might be a high sum that you invest initially to set up the solar energy system, but after this is done, you save money for an entire lifetime with extremely low electricity bills and the value of the property increased. 


Calculate your savings

The Grid Connected Rooftop System or GCRT is widely available in the country, and the government is doing its best to promote it - but the real deal is whether or not solar systems can make up for this investment. If the answer to this question is yes, then how many years will it take for the solar system to recover this cost? The rate of electricity is only increasing, and so GCRT proves to be the best option if you want to save money. Furthermore, the incentives provided by the government to install these systems, makes it the best financial investment you can make. 


1. Instant savings:

While we know that solar energy can reduce your monthly electricity costs to a large extent, the main question that must be answered is - by how much does it get reduced. Solar panels provide any home or commercial building with electricity, without the requirement of any utilities but sunlight. This factor, paired with the attractive incentives offered by the government will reduce your expenditure to a new low. 


Compare the bills with the traditional utility bills from earlier times, and you will see a huge difference. With a solar energy system, you end up not buying electricity, but actually saving it. 

2. In-built savings:

The electricity bill that comes in every month will get reduced, so that you can enjoy small energy savings. Over a period of time, these savings will add up to make a large sum of money that will eventually help you repay loans that you might have taken to purchase the solar system. However, the important factor that you must know is that the savings will be different for different people. 


This difference is usually determined by the location, the amount of sun exposure, and a few other factors that play a crucial role in generating solar energy. Therefore, while some people might be lucky enough to get 100% savings, you might only get 40% or vice versa. 


3. Long-term savings:

Now let us talk about the long-term savings that solar energy systems bring with them. You can rest assured to receive a return every month for the initial investment that you make on the solar system. You do not have to pay for any utility company every month like before - and that means a lot of savings. This way, you accumulate energy and its cost is paid to you directly, through various accounting and adjustments. 


You must understand what this means. Not only will you save energy every month, but you will get paid for the extra units of energy saved. 


4. Depreciation benefits:

Depreciation benefits are meant for the commercial users of solar systems and not residential users. When any industrial/commercial segment installs a solar system, they can claim a 40% accelerated depreciation (AD) from the government. This is one of the many incentives that the government provides to encourage the wider use of solar panels and solar inverters. The tax payment ultimately gets affected by this depreciation benefit. 


Eliminating or Reducing Your Electricity Bill


1. Generating your own electricity:

A Grid Connected Rooftop Solar System, or GCRT solar energy system allows you to decide how much electricity it will generate based on your requirements. Whatever your requirement of energy is for running various appliances in the house, the GCRT will generate only that much electricity. No external storage space is required, as the grid is itself a storage bank. 


Once you sync the energy generated with the grid, you can deposit whatever extra electricity is produced, and take that back when you need it. The DISCOM provides an extensive list of procedures and guidelines, and as long as you abide by these, the process is easy, simple, and extremely convenient. 


2. Security from rising electricity costs:

Electricity costs play a huge role in your overall budget to run a house, and constantly making efforts to keep these costs at bay can become a hassle. Fossil fuels like coal, oil, natural gas, and so on help in the production of electricity. All these elements, however, are quite susceptible to change due to the nature of foreign markets - which are largely unpredictable and unstable, to say the least. 


These electricity rates are always on the rise, but when you take the decision to switch to solar energy, you can work against this force of increasing rates. For the next so many years to come, you get to personalize and experience your own electricity rates. The best part is, these remain constant if you want them to. Your money remains under your control. 


3. Offset against electricity costs:

The way the GCRT solar system works is that when there is more electricity or energy produced by the solar panels than required, the excess gets stored in the utility grid. The general rule is for electrical companies to pay you for the excess energy you are giving them. Make sure to keep a track of these excess energy productions and the payments made. You can keep a track of the energy generated by the system using the “Net Metering” technology. 


4. Dictate your electric costs:

With a GCRT solar system, you can dictate your electric costs, as it entirely depends on how much electricity the system generates and how much of it you actually used. It’s not like your household appliances will not use power from the utility grid, but the overall costs will still be less because of the usage of solar energy. 


Indirect benefits of GCRT solar systems

While we have already discussed the direct benefits of GCRT solar systems, it is time to talk about a few indirect ones. 


  1. Loss of transmission and distribution is less.
  2. The gestation period is low.
  3. The system congestion gets reduced, along with an improvement in the grid voltages.
  4. Over the span of a year, there is an abatement of a total of 60 million tonnes of CO2
  5. Daytime peak loads are better managed.
  6. 20-25 years of free electricity is generated after the initial ¾ years.


Solar batteries are usually of two types - AC and DC batteries, and the difference between these two lie in their efficiency levels, as well as the manner in which they connect to the solar panels and grids. AC batteries will be more advantageous if you add it to your existing solar system, since it is more cost-effective than a DC battery. However, in the case of a new solar system, DC batteries will be a better addition to the system, as these are simpler to operate. 


In this article, we will see what is the difference between AC and DC batteries, and try to find out which one is the best for you. 


How solar homes use AC and DC electricity


DC, or direct current is the current that flows in a single direction, to provide the circuit with power. On the other hand, AC, or alternating current tends to flow in two directions and keeps switching frequently. AC electricity is mostly preferred in homes for various electrical appliances because it can be safely transmitted over long distances and is more affordable. 


In most solar homes, the solar panels produce DC current - which flows into the solar inverter where it gets converted to AC electricity to be used by household appliances. Direct current is used by batteries as well, but they need to be connected to an inverter as well. Solar battery banks are useful, especially when there are frequent power outages in your locality. 


DC-coupled solar batteries

If you have a home solar system and you install a battery alongside it, special equipment can be installed by the solar installer. This equipment works to connect the solar panels to a charge controller, and then gets connected to a battery bank. After that, a connection is made with the solar inverter, and ultimately the solar panels are connected to the main electrical panel in the home. This entire process is referred to as the DC-coupled battery back-up, because DC electricity is used to charge and discharge the battery. 


1. Advantages of DC-coupled batteries:

2. Disadvantages of DC-coupled batteries:


AC-coupled solar batteries


For a very long time, only DC-coupled batteries were available, and those people with existing solar systems did not have a feasible way of getting any battery back-up. However, AC-coupled solar batteries have recently become available and are quite popular among such people. They require this power back-up to provide them with electricity during times of power cuts. 


A DC-coupled battery makes no sense for anybody with a solar panel already attached to a grid-tie inverter or a microinverter. It would only mean replacing an already working system with another expensive new equipment - which is a complete waste of money. Instead, the solar energy system users can now simply purchase an AC-coupled battery, and install it with the existing solar energy system in place. With the AC battery, there is no complicated long process of converting the electricity and then reaching the main unit. This one comes with its own inverter, which means that the current directly reaches the appliances in the house. With special wiring, the solar panels or the grid can be used to charge the battery. It also acts as a back-up power, when the grid goes down and there is a power outage. 


1. Advantages of AC-coupled batteries:


2. Disadvantages of AC-coupled batteries:




In this article, we have tried to inform you about certain crucial factors that you must have knowledge about before investing in a solar power system. One of the main factors is the difference between AC and DC batteries that are used in solar systems. We have covered topics like how the two types of batteries function, their mechanism, the differences between the two, the similarities, and the advantages as well as disadvantages. Solar systems can prove to be highly beneficial for your home or any commercial building, if chosen properly and with a lot of care. 


We hope this article helps you navigate your way through to find the perfect solar system for your home or understands your existing system better. 

With the rising threat of climate change, conventional energy sources are being fast replaced by non-conventional, renewable sources of energy. Solar energy is one such non-conventional source, which has enormous potential. Moreover, installing solar panels on agricultural land has immense potential in a country like India - and this arises from the fact that it can meet the power demands of areas where there is a shortage of power supply, and are subject to frequent power cuts. 


Solar panels are being installed in the farmlands on a rapid scale. However, there is a problem: fitting these panels require land and this, in turn, reduces the area under cultivation, affecting farmers’ incomes. However, there are ingenious ways to solve these issues. As a consequence of proper advertising and various awareness programmes, farmers are now beginning to learn how to use solar panels for the purposes of farming. In fact, the use of solar energy for farming can be an excellent solution to increase farm productivity. It is a unique and extremely environmentally friendly farming solution. In a country like India, where farm incomes are experiencing a steady decline over the years, the installation of solar panels has the potential to make farms more sustainable and farming more economical for farmers. 


The initial cost of installing a solar panel is high. However, in the long run, it leads to increased farm efficiency and output. The best way to install a solar panel on farmland is to install them a few feet above the land. In this way, the farmer can grow plants below the panels, thus, reducing wastage of area under cultivation. Crops that can grow under the shade, such as pollinator crops, bedding plants, small-statured fruits, trees, shrubs, and vegetables are some of the crops which are best suited to grow under the shade of solar panels. Besides, if these panels are installed at a proper height, small and medium-size livestock, such as most cattle breeds and non-draft breeds, can graze under them. Besides, a number of ongoing studies are pointing out the fact that growing plants under the solar panels can lead to increased solar cell efficiency, as it creates a cooling microclimate. There are other ways in which farmers can reap the benefits out of solar panels, without compromising on farm output. For instance, not all land owned by farmers are put under cultivation. They can use these lands to install solar panels. 


However, there are certain problems. Even if you place the solar panel a few feet above the ground, it is difficult to do things like hoeing and ploughing. Using farm equipment under the solar panel becomes a big challenge. Even if you are able to solve this problem, there emerges another, even bigger problem: not all crops require shade. Therefore, you need to choose crops that can grow easily under the shade, while at the same time, does not affect your farm’s productivity and farm income.


In recent years, improvements in technology have solved these problems to some extent. Loom Solar is a startup that began in 2018, and today, they are one of India’s leading manufacturers of monocrystalline solar panels. These panels are much more efficient and require 15 to 20 percent less space for installation, as compared to other solar panels. Besides, there is ongoing research on bifacial solar panels. These panels are capable of using the reflection of the sun rays on the ground to convert them into solar energy. Researchers are planning on implementing this technology on different types of soil, with different kinds of crops planted. Thus, these are extremely efficient solutions. We need more such solutions, so that farming can be more sustainable.


One might wonder that use of solar panels in farmlands is a new concept. However, this concept, also known as agrophotovoltaics or APV, was introduced three decades ago by the physicist Adolf Goetzberger. There is currently a debate on the efficacy of using solar panels in farmlands. In a study, the same set of crops (potatoes, wheat, clover grass, etc.) were planted with and without solar panels. In the farmland where solar panels were installed, there was a decline in farm production in the range of 5.3 to 19 percent across various crops. However, the electricity generated with the solar panels reduced energy bills of the farmers, and thereby, led to an overall increase in farm efficiency by 60 percent.  


We need more and broader studies to determine the efficacy of solar panels in farmlands. Studies on themes like microclimate, density of grass due to the installation of solar panels, infiltration of stormwater and its effects on solar panels, etc., need to be undertaken more rigorously to further understand the efficacy of solar farms. Such studies are already being conducted. 


One of the biggest challenges of a solar farm is the initial cost involved. Not only are solar panels costly, but you also need an experienced engineer or technician for their installation. Besides, there must be other mediators between the farmers, the researchers, and manufacturers of solar panels. Bringing together so many resources require proper management and intervention, and this is why the state should play a more active role in this process. There is a need to bridge the gap between the farmers, and those who have the technical know-how. 


One often wonders if non-renewable energy sources like solar energy can offer sustainable solutions in developing countries, like India. Are things like solar farms even sustainable on a large scale? Many people might not know, but India has the lowest solar power electricity generation cost in the world. Further, the single largest solar power plant in the world is located in India (Bhadla Solar Park). Solar energy is the future to India’s fast-growing electricity generation capacity. The manufacturers of solar panels are also growing in number in this country. 


Thus, solar panels offer an ingenious sustainable farm solution. It can also lead to increased incomes for the farmers, which is a boon for a country like India, where farm incomes have been witnessing a steady decline. Solar farms are the future of farming!

Inverters are a blessing in a country like India, where power cuts are so frequent and happening all the time, especially in certain rural pockets. The most effective, pocket-friendly, and even eco-friendly way of conserving energy is by using solar energy. During the times that you do not have access to electricity, solar inverters that get current from solar panels can be of great help.

The main work of solar inverters is to store the solar energy in the batteries and use it when there are power cuts. People are gradually realizing how cost-effective solar inverters are and opting for them. Due to this reason, a plethora of brands has emerged that are competing against one another to manufacture the best solar inverter in India.

In this article, we help you navigate your way through certain important factors to be considered before buying a solar inverter, and some of the best products that are available in the market.

In this section, we provide you with a list of some of the best solar inverters in India based on the quality, features, performance, warranty, and service of the products. These have been chosen very carefully and after sufficient research. However, to get a more holistic picture, you must do some research of your own to understand the kind of products currently available in the market, and if they meet your requirements.

Factors to be Considered Before Buying the Best Solar Inverter

There are a couple of crucial factors that you must take into consideration before buying the best solar inverter in India. These factors will provide you with some basic knowledge that you need to have before buying this appliance. After all, it is a long-term investment and you would want to get it right.

1. Types of solar inverters

2. Output type

The solar inverters are further divided, depending on the kind of output they have. This section talks about the 3 kinds of outputs in solar inverters.

3. Efficiency

Efficiency is another important factor that you must take into consideration before buying the best solar inverter in India. The ratio of the output power to the input power is what will tell you the efficiency of the solar inverter. The load on the inverter determines its efficiency to a large extent. Since some power is always lost because of the generation of heat, 100% efficiency can never be achieved.

4. Size

There are two power requirements that the solar inverter should meet - one is the peak power and the other is the typical power. The maximum amount of power that the inverter can supply within a fixed period of time, is known as the peak/surge power. Heavy appliances like pumps or refrigerators require this surging power to start the motor.

On the other hand, the power that is supplied at a standard and steady rate is called the typical power. This tends to be far lesser than the peak power. If you are looking for the best solar inverter for a home in India, then you can buy one with 50 watts power supply - as that is enough.

5. Power rating

Solar inverters are used for various purposes, both at home and other larger, institutional spaces. To suit every purpose, they are available with a power rating ranging from anything between 50-50000 watts. If you are planning to buy a solar inverter for your home, then you can easily work with less than 11000 watts. Most standard solar inverters come with a power rating of 50-5000 watts.

6. Internal protection features

Every electric appliance is constantly under the threat of some damage or the other, especially the heavy appliances. You must purchase a solar inverter that protects the various components from getting damaged due to lightning surges, overload, and so on.

7. Battery life

The battery life of the solar inverter is yet another factor that must be taken into consideration before buying any model. The battery life determines how long the inverter can function using the power supply. The number of cycles or charges that the inverter requires illustrates the battery life of the solar inverter. The unit used to express these cycles is usually milli-ampere per hour, or mah.

Any expert or previous user of solar inverters will advise you to buy a solar inverter with long battery life. Since these batteries use elements like nickel-hydride, lithium-ion, and so on, they tend to consume less power. Thus, these batteries are preferred.

8. Manufacturer’s warranty

Before buying a solar inverter, you must check for the manufacturer’s warranty. The best solar inverter company in India will provide you with a good warranty that lasts for many years. If you find such brands and products, then you should choose them without any delay. However, do not make these decisions in a hurry, and try to compare the warranty period offered by different brands. Settle for reputed brands that provide years of warranty.

9. Budget

Your budget for buying a solar inverter will largely determine the kind of inverter you get and its features. With a big budget, you can always go for the high-end models that provide a longer battery life, along with various advanced features or options. With a lower budget, you can still find inverters that meet your requirements.

10. Solar System Monitoring

There is some form of remote monitoring that every solar inverter provides, which helps to track the performance of the device. You need to track its operations and performance with the help of a monitoring system that is accurate and reliable. Check for solar system monitoring before buying any particular model.

11. Solar inverter function and problems

This additional point is to give you a rough idea about certain issues you can face with a solar inverter. In any grid-tie solar system, a solar inverter is the most complex and sophisticated component. There is no denying that solar inverters are sturdy and built to resist heavy rains, winds, and other weather conditions. It does all this while generating a high amount of energy for a long period of time.

However, if you wish to put less pressure on the inverter, it is best to place it in a sheltered place, so that the quality of the machine remains intact longer than the stipulated time. If placed outside in an area without any shelter, the inverter will be exposed to humidity and high temperature, which will invariably cause some fault.

To avoid any of this, it is best to place the solar inverter inside a garage, or somewhere away from direct sunlight. This can significantly increase the lifespan of the solar panel.

FAQs on Solar Inverters in India

Q1. Do solar inverters turn off at night?

Solar inverters get their energy from solar panels, which respond only to sunlight. Hence, solar inverters do turn off at night and wait to absorb all the sunlight in the morning. Do not be worried or think something is wrong when you see that the device has turned off.

Q2. Where should a solar inverter be installed?

 You should install the solar inverter in a place that is away from direct sunlight and that has a proper system of air circulation. The place should also be easily accessible to you for the purpose of maintenance. It should be resistant to moisture.

Factors to consider before buying the best solar panels

In this section, we have covered some important factors to consider before buying the best solar panels in India. Fancy advertisements might try to lure you into buying certain solar panels. Do not fall for this trap. Know these important factors, check whether the solar panels you are considering to buy meet the requirements, and only then go ahead to make a decision.

1. Types of solar PV systems

There are mainly 3 types of solar PV systems - Off-grid, on-grid, and hybrid solar systems. It is important to have a basic idea of how each one functions and operates so that you know which one will be ideal for your home or office.

If you are living in an area where power cuts are frequent, this power system will be perfect. However, the main electric power system of this solar system is unstable and unreliable.

With this system installed, you can save the maximum amount of money and get maximum efficiency as well. These can be called the best efficiency of solar panels in India.

2. Type of photovoltaic panels

There are 3 types of solar panels - Mono-Crystalline solar panels, Poly-Crystalline solar panels, and Thin Film solar panels. It is crucial to discuss these three types in a little more detailed manner in this section.

The efficiency of the solar panel is the most crucial aspect. As efficiency goes up, the requirement for the number of panels goes down. The ability of the solar panels to convert sunlight into electricity determines its efficiency and effectiveness. If you have space issues, it is best to look for solar panels with maximum efficiency, as they occupy the least amount of space.

Efficiency tends to reduce if you allow dust and dirt to settle on the panels, and to avoid this, you must clean the panels at regular intervals. Place the panels in a spot that does not get any shadow, as this too can lessen the effectiveness of the solar panels. The tilt of the panels also plays a significant role in determining its efficiency.

3. Temperature coefficient

Sunlight is the only source of energy that solar panels depend on, but sometimes the heat can get too much for the solar cells. Extremely high temperatures can destroy the cells as well. The efficiency of the solar panel is determined by this temperature coefficient. Efficiency is better when the temperature coefficient is lower.

If the temperature is greater than 25 degrees Celsius, then both power output and voltage drops, and the current increases. On the other hand, when the temperature is less than 25 degrees Celsius, both the power output and voltage increase, but the current drops. To reduce the intensity of the sunlight during the day, you can always tilt the panels. The best solar panels available in India are those that come with automatic tilting for this purpose.

4. The durability of solar panel

Another crucial factor that must be considered before buying the best solar panels in India is its durability. Solar panels are meant to stay outdoors, and they have to tolerate nature’s wrath at every turn. Hence, the solar panel you purchase must have the strength to stand straight through it all. Before reaching markets to be sold off, most solar panels go through rigorous testing against harsh weather conditions.

The testing is done depending on the weather of the country where the panels will be sold, since natural conditions differ from place to place. You can read reviews by other customers in India, or simply rely on a trial and error process to ensure that you buy the most durable solar panel.

5. Solar panel ratings

The capacity of the solar panel to generate electricity under certain specific conditions is suggested by the solar panel ratings. You can rely on these ratings to make a comparison between different solar panels. If a solar panel shows a high rating, then it means that it creates more electricity than another solar panel with a lesser rating.

However, when two solar panels have the same rating but different power ratings, it usually means that the one with a larger power rating is also bigger. You need to bring in other factors to make the comparison in that case.

6. Solar panel price

The price of the solar panel is yet another factor that you cannot negate while looking for the best solar panels for homes in India. People usually search for panels that give the maximum performance at a low price. However, you must keep in mind that a lower budget might also mean lesser features and lower efficiency. Always check for the quality of components, warranty period, after-sales service, installation charges, etc before buying the solar panel. There are also several financing options available for purchasing solar panels.

7. Solar panel certifications

Your solar panel must be certified by recognized bodies, as this allows you to get various subsidies and also makes the product trustworthy. It is thus best to buy solar panels that are approved by the MNRE (Ministry of New and Renewable Energy). Only those solar panels that are grid-connected qualify to get subsidies from the government.

8. Manufacturer’s warranty

Even though we have mentioned this factor towards the end of the list, the warranty remains to be one of the most crucial factors that you must take into consideration before buying the best solar panel in India. It is also the trickiest factor. There are two types of warranties that come with a solar panel - the manufacturer’s warranty, and the performance warranty.

The former covers problems such as durability, manufacturing defects, or certain environmental issues. The manufacturer’s warranty that most brands offer usually ranges from 5-15 years. This warranty covers any damage caused due to environmental disasters like storms, cyclones, and so on.

The performance of the solar panel is expected to degrade every year, and this is called the panel degradation rate. The warranty provided by some companies on this degradation is known as the performance warranty. This ensures that the degradation of the solar panel will not be beyond a certain percentage within a stipulated time. Usually, the degradation percentage every year is 0.7%.

9. Power requirement

You must have a rough estimate of your power requirements before investing in a solar panel. Whatever appliance that you will connect to the solar panels, such as fans, lights, air conditioners, and so on, makes up your power requirement. You must calculate the total load all this might add up to. Further calculations will give you the UPS VA rating, and you can go on from there with a few more calculations to arrive at the approximate panel size that will suit your power requirement. We have more specific guides on 50Watt, 100Watt, and 375Watt solar panels.

You must make sure that the UPS is compatible with the voltage and the current of the solar array.

10. Check the mounting system

Mounting systems are the things that keep the solar panels mounted at all times. The mounting system protects the solar panels from getting uprooted during harsh storms - which are especially helpful if you live in a cyclone-prone area. There are mainly two types of mounting systems - flush mounting and roof or floor mounting.

The former can be easily installed and is reasonably priced, whereas the latter is more expensive, but it ensures a long-lasting life for the solar panels. The roof or floor mounting system is necessary for places that are prone to cyclones. The panels cannot be kept steady with flush mounting when winds pass through in high intensity.

11. Solar inverter

A solar inverter is needed when you are fitting solar panels for your home. It converts DC into convertible AC. A premium quality solar inverter will ensure that less energy is wasted at all costs. This will not only save on your monthly electricity bill, but also save the environment from deteriorating so rapidly.

12. Elements in a solar PV system

Lastly, it is important to have some basic knowledge about the few elements that make up the solar PV system. These are:

In this section, we present to you detailed reviews of some of the best solar panels available in India. Choosing a suitable one for your home or office can be easy with this list to refer to. However, the list is limited to a certain number of products, and you should do your research on some other products to keep your horizons open.

Frequently Asked Questions

Q1. What happens to solar power that is not used?

There might be times when you produce more solar energy than you can consume. During such times, the excess solar power is used to charge the grids and keep them in good condition. This reduces the load on the normal electricity usage and helps you save on your monthly electricity bills.

2. Can I run the entire house on solar power?

Running the entire house on solar power will require a higher number of grids, and can become quite an expenditure, because of the various heavy-consumption electrical appliances we use at home. Thus, it is better to use solar power only for a few appliances, or use it as a power backup for times when there are power cuts in the house.

3. On average, what is the lifespan of a solar panel?

 Most companies provide a warranty of 20-25 years on the solar panel - which means that the minimum lifespan is that much. However, with electrical appliances, the trick to a long life lies with good maintenance of the product. When maintained well, a solar panel can last for as long as 40 years.


This article aims to help you out with an electrical appliance that laypeople usually have no idea about. However, once you know all the details and information about solar panels, you will realize what a great invention of science it is, and how helpful it has proved to be, in providing electricity to the remotest parts of India. Do your research to know more about the benefits of solar panels in moving towards a sustainable future.

A lot of people have absolutely no information regarding this topic, and in this section we wish to correct that mistake. Solar panels are subsidized to varying degrees by the government in India, in order to encourage the use of sustainable living standards that are consistent with our age-old traditions and beliefs of living in harmony with our natural environment. 


This subsidy works in a very simple and efficient manner. In order to give people added inducements and incentives to permanently shift to sustainable patterns of energy consumption and production, the government provides financial support for the installation of solar panels in residential homes. This transforms the home into a completely self-sufficient clean energy environment, that acts a great relief to the natural surroundings and contributes to less pollution. 

There are mainly three different types of subsidies available, which can be used to make the solar energy transition. 


1. Residential Home Owner Subsidy 

The first is the customer benefits, which are only applicable to residential home owners who wish to make the big investments required to install solar panels. The solar energy system requires big investments, and the subsidy acts as a welcome relief to people who are ready and willing to make that investment on the best solar panels.


If you install the solar panels using the government subsidy, you will also get a 5 year warranty on your panels from the solar system installation company. 


2. Channel Partner Benefits Subsidy

The second kind of subsidy is the channel partner benefits - which are explicitly designed to tackle the issues surrounding the trouble faced by common individuals to avail these subsidies. Once the channel partner comes into the picture, they themselves work to sort out the various elements of the government subsidies. 


3. DISCOMS Benefits Subsidy

DISCOMS Benefits constitute the last viable method to get the most out of the government subsidy, so that all parties involved can be happy. The customer is entitled to his or her financial aid on the one side, whereas the channel partner is pleased to add another new customer to the books. And of course, the government is happy, because it is one step closer to reaching its target by encouraging the use of solar panels, which will help in reducing emissions and ensuring a clean better environment for all. 


Subsidy Demerits 

As far as the subsidy demerits are concerned, we have found different demerits which we would like to mention clearly for your knowledge. The only major problem with general customer government subsidies is that you will be in a position where you cannot install the best solar panels from some of the most well known international popular brands. These include brands such as Loom Solar, Luminous, Microtek, Exide, Enphase, Solar Edge, etc.


As far as the channel partner benefits are concerned, here also, we can find different demerits. The first obvious demerit that we have discovered by speaking with many industry experts, is that the high level of initial investment required, often turns out to be a serious issue. 


State Subsidy Schemes 

We would also like to briefly touch upon some of the unique aspects of this subsidy scheme in different states of India, and what are the features exclusive to particular states. 


We will start off with the state of UP, and although it is one of the most backward states in India, the government there has adopted an aggressive subsidy scheme to transform the state into an eco friendly state as early as possible. The government has announced a healthy 15000 to 20000 overall subsidy amount per KW for rooftop residential projects. It also has the mechanism in place for online application, which makes the entire process a lot more easy and quick to finish off. 


Next, we come to the state of Kerala, which has been pushing ahead with its green energy initiatives as a coastal state. The state subsidy amount is the balance that is left after all consumer payments as well as CFA. The size of the rooftop solar panel system can be up to a maximum of 10kW. Like in UP, Kerala has also managed to set up a robust and highly efficient online application system, that is very useful throughout the entire process. 


The state of West Bengal, which has always shown the way in terms of progressive solar energy transitions, has actively sought to promote the use of sustainable and clean energy systems. The state government-owned WEBEL was one of the first solar panel manufacturing units in India. West Bengal has a mandatory rule that requires all housing societies to derive a minimum of 1.5 percent of their total electricity load. 


Next we come to Maharashtra, which has also become renowned as a hub of initiating solar panels. The solar project in the state is managed by the MEDA, and it has managed to get the fourth-highest installed rooftop solar power generation capacity across the country. The state government in Maharashtra is also looking at new and innovative policies designed to encourage the use of solar panels in cottage and micro industries, which is another powerful initiative. 


If you are looking to install solar panels for a grid-connected rooftop solar power plant, you will get a subsidy of around 30 percent of the total cost - which is a very good deal and gives you a good incentive to invest in renewable energy forms. The CFA can be availed by a host of different parties including schools, health institutions, etc. as well as organizations engaged in the social sector. 

If you have chosen to make the shift to renewable solar energy, then we should congratulate you first and foremost, as your decision will have positive consequences for the environment. It will also end up in some significant savings in terms of energy bills in the long run. However, it is important to consider which type of solar panels are best suited for your energy requirements, and this is the question we will explore in this section. It is important for you to be aware of the fact that the solar panels you install are not directly responsible for supplying power to your appliances. Instead, it merely charges the battery, which in turn is responsible for providing power to your devices and appliances, depending upon the requirement. 


Keep in mind that the total home load that you will be putting on your panels is basically dependent upon your inverter capacity. On the other hand, the amount of backup power you can have access to, depends largely on the range of the battery that you will be using. So it is important to buy an inverter and a battery that is of good quality and that will allow you to get the best out of your solar panels. Typically, we recommend that the range of the panel should ideally be double of that of the battery to get optimum levels of performance. 


Residential or Commercial Purpose 

First, to start things off, you should know that 12v panels are ideally best suited for small residential homes or smaller housing projects. 24v panels on the other hand, have been designed to bear more heavy loads. Apart from this, we will also explore a few other technicalities which will allow you to make a more nuanced choice. 


Battery Compatibility 

One of the most important things to consider is the efficiency rating of the battery. Make sure that you pair a 12v battery with a 12 v solar panel. You should also make note of the fact that 24v rated batteries are not available in the market. So if you wish to install 24v panels, then you can join two different 12v batteries, in what is called a series connection to power your panels without issue. 


Inverter Compatibility

The next aspect to consider is the matter of inverter compatibility. Just like the solar panel should be compatible with the rating of the battery, the same goes for the rating of the inverter. So basically, a 12v inverter should be paired only with a 12v solar panel. The market also has 24v rated inverters, so you can easily pair that with 24v panels if you wish to do so. You also have the option of 48v inverters if you’re looking to install some really heavy duty solar panels for commercial or other non-residential purposes. 


Charge Controller Compatibility 

Following this, we move to the question of the compatibility of the charge controller. Just like previous compatibility markers, this one also has to have the same rating as your panels, battery as well as the inverter. You should specifically make sure that the rating of the solar panel is not higher than the rating of the charge controller, as this can lead to serious damage to your panels. 


Practical Application Assessment 

Now we come to the question of application, and whether a 12v panel or a 24v panel will be better suited for your needs and requirements. A 12v solar panel supports a range of different applications such as street light, tourist vans, shops, small homes, solar water pumps, fishing boats and many others. 


24v panels on the other hand, are considered to be ideally suited for large sized homes, which have many different heavy load appliances and devices which are used on a day to day basis. They are also ideally considered to be the best option for commercial spaces as well as large scale businesses such as hospitals, banks, factories, public parks, solar parks etc. 


Finally, we come to the range of different types of panels. For your information, 12v panels are available in 10W, 20W, 40W, 50W, 125W, 160W and 180W variants. On the other hand, 24v panels are available in only two selected variants, which are 330w and 350w respectively. 


Solar energy is a relatively new source of energy, and it is yet to be harnessed to perfection. However, in the last few years, the number of individuals as well as collectives who have installed solar panels for their homes and industries, have multiplied. Despite more knowledge about solar energy and better information all around, there still continue to be numerous myths associated with solar energy and the use of solar panels. In this section we will try to dispel some of those rumours and set you on the right track. 


Doesn’t Work in Cloudy Weather 

The first major misnomer often perpetuated about solar panels, is that it does not work in cloudy weather. Makes sense right? Solar panels need sunlight to convert energy into power, and if there are too many clouds blocking the sunrays, there is no energy to convert. Wrong. Solar panels work with not only strong sun rays, but also common visible light i.e the natural light of day which helps us to see things. Of course, it is important to state that a bright sunny day will be a lot more beneficial for you to charge your solar panels effectively, but this does not mean that a cloudy day is totally worthless for your panels. 


Require Warm Climate to Function 

The next rumour that we wish to dispel is that solar panels need warm climate conditions to work effectively. This is based on the misplaced idea held by some that solar panels use not only light as a source of energy to charge themselves, but also heat. This leads them to believe that solar panels are ineffective in cold temperatures - which is completely untrue. Infact, the opposite of this is actually somewhat true. Solar panels require cooler climates to work best and not the other way around. Cold weather conditions actually manage to increase the conductivity of solar panels, and this allows them to produce more energy. So be sure to know that climate conditions are not really that critical in the functioning of your solar panels. If the panels receive adequate sunlight throughout the year, then you have nothing to worry about. 


Causes Damage to Rooftops 

Another common misconception that people have about solar energy usage is that solar panels could end up causing long term damage to the roof of your house. This is another illogical piece of fake news that should be nipped in the bud right away. Solar energy and solar panel technology is now considerably developed, and is at a stage where it has been refined for many years. Modern solar panels come with highly functional and sophisticated designs, which bear no threat to the roof of your house whatsoever. 


Questionable Return on Investment 

Next we come to a more genuine and understandable concern that is shared by a lot of people in India, and in the wider developing world in general about the use of solar panels. It is common knowledge that transitioning to renewable solar energy requires a pretty big investment, and this raises obvious doubts in the minds of many. One of the biggest doubts is regarding the question of how quickly you will get a return on your investment, and whether it will be worth it or not. Of course, it is difficult to answer exactly how and when the ROI will come about for you, as these are based on factors of subjective judgment.


However, we can say for sure that once you invest in solar panels, you will not be required to spend any major money on them for a long time, and it will serve you well for years to come. Good quality solar panels will not require a lot of spending on serving and maintenance. You might want to get the yearly check up done to make sure everything is running well, but other than that, there is really not too much scope for things to go wrong.
