The use of solar panels has increased over the last few years - not only in large institutions but also in individual homes. This is mainly because people have realized that it is a much more pocket-friendly and environment-friendly option. Solar panels are also widely popular in areas of India that suffer from frequent power cuts and thus, people rely on these panels for electricity.
How much ever-helpful these appliances might be, you cannot make a random choice without knowing certain basic features of solar panels. This article aims to inform you about the important factors to consider before buying the best solar panels in India. Once you have a basic understanding, you can easily buy a solar panel that meets your requirements.
There are so many brands selling solar panels in the market today, that deciding on a single one can be quite the task. Read through this article, as it is sure to help out.
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.
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.
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.
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.
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.
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.
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.
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.
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%.
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.
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.
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.
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.
Loom Solar is a renowned brand, and one of the best solar panel companies in India. When we think of solar panels, we imagine them producing electricity for a large place, and not for small requirements. However, this is not always the case. You might require solar panels with lesser energy output. Loom Solar provides you with such solar panels here.
To cater to small power requirements, this Loom Solar panel offers a power output as low as 50 watts. However, just because the power output is less, does not mean there is any compromise on the efficiency levels.
It produces as much efficiency as a 350-watt solar panel would do. The mono-crystalline solar cell is used to manufacture these solar panels, and this ensures that electricity is produced even under low lighting conditions.
Even when it is cloudy, these solar panels produce quality current for any house. The 12V design is used to manufacture the mono-crystalline cells. There are additionally four busbars and 36 cells that come with the solar panel.

The junction box is made of aluminum alloy, which makes it resistant to corrosion, and for this reason, it remains unaffected by rains. It has IP65 certification to be all weather-resistant.
Microtek provides a warranty of 25 years on these solar panels, and if there is any damage or dispute within this period, then the company takes care of it. All 36 cells are protected by the 3.2 mm EVA (ethyl vinyl acetate).
Even when the lighting is low, or it is cloudy, the panel exhibits exceptional performance under all circumstances. The best feature of these solar panels, however, is that it does not create any noise and can be used to run sensitive appliances.
Sukam is another leading player when it comes to solar panels, as it has been trusted by the people of India for so many years now. The solar panels that Sukam manufactures are ranked to have the best efficiency and performance - all of this at an affordable price. This particular solar panel has a power output of 100 watts - which is high enough for a few electrical appliances, not too many heavy ones.
There is an iron frame all around the solar panels, that protects the solar cells from any damage. A+ Grade anti-PID poly-crystalline cells make up these poly-crystalline solar panels, and they have a current conversion capacity of 16%. These panels have been designed strictly in compliance with the IEC standards, even when the efficiency levels are not as that of mono-crystalline cells.
You have to provide the Sukam solar panels at least with a space of 12 feet for it to be mounted properly. You can easily set up this solar panel on the terrace of your home. These 100W panels rank high on durability, as they stand firm against tough climatic conditions like heavy rainfall, storm, snowfall, and so on. The solar cells have a protective glass coating around it, and the panels are made to go through durability and reliability tests before being sold in the markets.
Sukam provides customers with a 5-year warranty on the solar panels for any physical damage that might take place. The overall warranty on the panel is 25 years long. Even a 150 mAH battery can be easily changed throughout the day by this solar panel.
When compared to various other solar panels, this one does not work as well in low light conditions or when it is cloudy. Another big disadvantage of these solar panels is that it has a power tolerance of ± 3%, whereas most solar panels come with a positive power tolerance.
Much like Loom Solar is known to make the best monocrystalline solar panels in India, Luminous rules the scene when it comes to poly-crystalline solar panels. They offer a constant 20% efficiency. Its operating efficiency is more than 16% on all the panels that the brand manufactures. It requires nothing more than 10 sq. feet of space, and any home terrace can easily provide for that much.
The output energy of these Luminous solar panels is 160 watts, and this can easily charge a battery of 12 V power without any difficulty at all. When there are power cuts in the house, the energy stored from the solar panels can be used to power electrical appliances at home.
A+ Grade anti-PID poly-crystalline cells are used to make the panels, and they can charge a lead-acid tubular battery comfortably throughout the day without falling short of electricity. The dimension of this solar panel is roughly 4.8 feet, and it can charge the battery between 9 am and 5 pm.
When the sun is at its peak - which is usually the time around noon, the solar panels can generate their peak energy supply at 8.7 amps.
What makes these solar panels reliable and trustworthy, is the fact that they completely comply with the IEC standards and deliver a remarkable performance all the time. The warranty is also quite appealing, as Luminous offers a 25-year warranty on these solar panels.
The solar panels come with an anti-reflective coating that provides resistance against winds, storms, and snow. However, as many appliances have some other drawbacks, so does this one.
Since these are made of polycrystalline cells, they are far less durable than the mono-crystalline cells. Other than that, these Luminous solar panels provide great reliability and at the most affordable price imaginable.
While mono-crystalline solar panels tend to have the best durability, poly-crystalline solar panels like this 150-watt Sukam solar panel are much more affordable. The technology involved in making these solar panels does not guarantee as much precision or durability and hence, the efficiency levels are also affected because of this. However, these solar panels can produce a strong enough electric current of 8.5 amps at its peak.
The tolerance levels of these solar panels are plus/minus 3% and thus, the output energy usually fluctuates between 145 W to 155 W. Cloudy days mean a negative tolerance, and bright, sunny days mean positive tolerance and the advantages that it brings. Sukam solar panels are made to go through stringent durability and reliability tests, and only once they emerge successfully are they sold in the markets.
You can connect these solar panels to home inverters, and expect them to operate smoothly without any hassle. During the day time, the panels can charge a 12Vbattery, so that it provides electricity to your home at night, especially if there is a power outage.
Tough aluminum frames and toughened glass are used to protect the solar panels from any kind of damage. Within this range, this is the best solar panel in India that you will come across.
A drawback of the Sukam solar panels is that you will require two solar panels to charge a 150 mAH battery - which can occupy quite a lot of space and become a problem if you do not have a big enough terrace for it. Sukam provides a 25-year warranty on the solar panels, which proves how durable these appliances are.
While both the Loom Solar panels that we have mentioned earlier in the list were mono-crystalline ones, this 10-watt Loom Solar panel is a poly-crystalline solar panel. This one is a small solar panel that can support only small electrical appliances with electricity. It delivers an efficiency level of 10.03%, which is pretty great considering the energy output that it has.
These panels are resistant to a high load of electricity. Even in low lighting conditions like when the weather is cloudy, the Loom Solar panels can produce electricity without any issues.
You can refer to this panel as an all-season panel that works effectively all year round. The solar cells have been manufactured using high-quality silicon. Since the panels are produced at a mass scale in an automated manner in factories, they have a standard design and no defects.
The best part about these solar panels is that you can carry them in a backpack, and take it wherever you go. It is highly portable because of its design and size. Even the installation process is so easy and convenient, that you can do it within minutes anywhere you like.
Even though this solar panel is relatively smaller and cheaper, the brand does not compromise in its protection, as it also comes with a layer of robust aluminum frame and glass around it.
The price at which these are available will leave you astounded. However, since it uses poly-crystalline technology, they tend to be less efficient and lack the level of performance that is displayed by mono-crystalline solar panels. Loom Solar still occupies the role of being one of the best brands in the field of producing solar energy for both rural and urban customer base.

The warranty that the company provides on the materials is for 5 years, 10 years on the performance of up to 90% efficiency, and an overall warranty of 25 years.
Two points that we like the most about this solar panel, is that it has very good mechanical strength and its efficiency and performance are quite decent, considering the range in which it is available. The one and only drawback of the solar panel is its temperature coefficient, which loses out on a lot of power for every degree Celsius rise in the temperature.
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.
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.
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.
