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.
