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 fulfil 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 potential 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.
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 the production as well as the collection of energy. As a result of this, there can be genuine ecological fallouts with regard to 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 fulfil the needs of numerous households in a particular area. Special attention should be paid to 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.
Any moderate to large scale construction of solar energy grids requires a great deal of cleaning and grading of the soil. This results in the compaction of soil overtime and also leads to alteration of traditional natural drainage channels which could cause issues related to the flow of water from local streams and waterbodies. With higher levels of construction comes higher risk of soil erosion which has a number of different adverse consequences for the region and its biodiversity.
Often, large scale solar energy projects require central tower systems. Each of these towers need 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.
Any kind of large scale industrial facility will always cause certain environmental issues for the air in and around the area, including a 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 which are carried by the soil. This eventually results in increased levels of suspended particulate matter and this could also have the effect on contamination of reservoirs.
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.
Besides the ones we have already mentioned, solar power installations could also have other social and economic impacts.Things such as 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 create a demand for migration of workers to the specified area and this affects things such as housing, public expenditures as well local government involvement.
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 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.
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.
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.
Solar panels should face north when they are 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.
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.
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.
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.
There are a few other factors that affect the solar panel tilt-angle that you must take into consideration before purchasing a solar system.
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.
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.
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.
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 correct or the ideal angle will help produce maximum energy.
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.
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!

However, we have no information about the warranty on this product.
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.
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.
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.
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.
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.
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.
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.
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.
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 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.
According to a 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 the 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.
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 another 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.
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 which 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 need to be replaced at some point during the lifetime of your solar PV system while the microinverters last for a longer period and requires 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.
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 more handy.
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.
There are a number of ways in which you can figure out whether your solar panel is undergoing deterioration. Following are some of them:
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 is something which 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.
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 a healthy functioning of the solar PV system.
In this article, we discussed in length about 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.

As for its solar capacity capabilities, it can give you up to 500 watts worth of power during the day when it is powered using solar energy. Another major reason as to why this setup is preferred by a lot of people, is because it is very compact and does not take up a lot of space in your home. This is especially important if there is some space crunch in the area where you want to set up the inverter batteries etc. All in all it ends up taking a megare 100 square feet worth of space. This package offers you 2 units of 150 Ah c10 solar batteries. As for the solar panels, you will get 3 units of solar panels with a rating of 325 watts each. This increases the cumulative power capacity to 1125 watt. That is quite a lot of power and enough to run several appliances at once.
To cite an example, using this setup you can easily run 5 Ceiling Fans, 20 Led lights, 2 televisions, 1 refrigerator, 1 mixer and charge laptops and mobiles. It also offers decent backup time that ranges from 36 hours for 100 watts to somewhere around 4 hours for a load of 500 watts. The inverter efficiency comes in at 97 percent which is quite impressive in its own regard. For all of these reasons, it is clear why this solar power setup gets a definite thumbs up from our side.
The Rooftop Urja 1KW solar setup has been specifically designed to operate as a Grid tie system and is recommended for locations which have a state monitored net-metering system. Net metering is a system where the excess solar power produced by your system gets transferred into the grid and therefore gives you reductions on your electricity bills as a result. These reductions can cut down your electricity bill upto 90%.. The net metering system is one of the major reasons why a lot of people have found good incentives to invest in a solar power system for backup power requirements.
Note that this system works only when the system is connected to a functioning electrical grid and you do not have the option of storing the energy produced by your panels into a battery to be used at a later time. So this works better as a backup power supply setup. In case you require backup, you will need to invest in a separate inverter backup system. Also make sure to check if your local system fluctuations can be handled by the specifications of this system. The overall kit comprises four units of 250Wp Solar PV Module each along with junction box and control panel.
Another important factor to keep in mind about this solar power setup is that this requires you to have shadow free floor roof space. The daily average energy generated using this system stands at anywhere around 4-5 units if we assume that there is a 100 percent grid tie availability which is not always the case.. This could definitely be one of the best if not the best residential solar systems that you can invest in.
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.
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.
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.
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.
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..
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.
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.
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:
The following are some of the major companies that manufacture bifacial solar panels in India:
In this article, thus, we talked about bifacial solar modules, and how they offer a comparative advantage over the traditional solar modules. We listed down the pros and cons of these panels, and also the name of the companies which make bifacial panels in India. Go through this article thoroughly to better understand your requirements - whether you’re considering bifacial panels for your home or office.

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.
The following are the components of a solar panel:
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.
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.
Ground-mounted and rooftop installations usually come in two main types of solar panels - thin-film and crystalline silicon.
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.
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.
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.
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.
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.
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.
