How do I choose a Solar Panel?
you often find yourself struggling with finding a reliable solar panel that serves your purpose as well as budget too. Don’t worry we can help you find a suitable match for your property. Since it involves long term investment so you need to rule out few parameters prior to taking a conscious decision. Let us get a clear impression of the things to be kept in mind before buying solar panel.
Cost of Solar Panel
The cost of the solar panel is probably the first parameter weighed on the list that the buyers look for.
The cost depends upon many variables like power in terms of Watts, its size the quality of material used, its durability, brand and the warranty. Choosing solar panels can be risky, but they have a long shelf life so ensuring a good-quality system is more important than choosing the cheapest option. Therefore, a key guideline for choosing solar panels is to consider cost. However, it should not be the only factor to consider, because the cheapest panel may not be the most effective and may not be the best choice in the long run.
The Quality of PV module
It is extremely difficult to rule out and determine the quality of the solar panel due to the sales jargon involved while selling.
However, some research about the company, its products, and customer reviews can be a helping aid in framing a mental image about the quality of the product according to customer satisfaction. Also, you can look up for a comparison for various brands and their specifications. Another thing that comes into picture is the way these panels are made and the quality of the materials used to build them. Different manufacturers produce varied qualities of solar panels that account for their efficiency and costing. There are vertically integrated solar panel manufacturers that control every stage of the production process. They attach great importance to quality and invest heavily in research and development. While on the other hand some manufacturers are merely involved in assembling and the technological involvement is least thereby lowering the ultimate price of the PV modules. The next important thing is to pay special attention to the detailed rules of the problem, including if there is a problem or anything that can be solved on-site. As an absolute minimum requirement, solar panels with a manufacturer’s warranty for at least10 years, including defects in crafting and materials are preferred. However, an interesting point to note here is that this is not the same as the 25- or 30-year performance guarantee provided by each module. The manufacturer’s warranty is what you need to verify and will take at least 10 years.
Type of Solar Panel
There are different types of solar panels available when buying:
Polycrystalline Solar Panel – Different layers of crystals are molded together to form a panel.
Monocrystalline Solar Panels – The entire panel consists of a single layer of pure silicon crystal.
Thin-film-thin film as the name suggests is made up of solar cells of thin-film deployed in thin layers into a substrate.
Polycrystalline solar panels are available in large quantities in the country, since compared to monocrystalline solar panels, their price is lower, but you have to choose according to the situation according to the following two types of different standards. Also, the location of the installation of the solar panel will determine the maximum power output you actually get from the solar panel. Monocrystalline solar panels work best when there is direct sunlight and there is little shade in this location.
However, if there are any major obstacles, they will work similarly to polycrystalline panels and a higher investment will be meaningless. So, check your geographical location, the area around the panel, and decide on a type and its efficiency. Monocrystalline Silicon has high efficiency and good heat resistance, and it takes up little space. There are also amorphous or thin-film silicon cells, which use the least amount of silicon and are not efficient.
Efficiency is of paramount importance when it comes to solar panels.
Solar panel efficiency refers to the amount of sunlight received by the solar panel which is efficiently converted into electricity, and therefore it accounts for how much electricity the system will generate. The higher the efficiency, the better is the performance of solar panels. Getting the largest and most efficient solar panels is not always the best option, because you may end up paying more to meet your energy demands. So, in addition to that, it is important that you must also evaluate and figure out your needs and find the panel that best suits your needs, this means not underestimating and not overestimating your needs and selecting the right panel.
Size of the PV module
The size of the solar panel includes the physical dimensions and the dimensions in watts.
You need to ensure that the panel you choose serves the requirement of your needs and space. The physical size of the panel will vary depending on the power of the system. The solar panel wattage is probably the most important thing you need to estimate correctly because underestimating the number will result in insufficient power and overestimating the wattage will result in spending more money than it actually needs.
This refers to the effect of heat on the operational efficiency of solar panels after installation.
Since solar panels overheat and will accelerate aging, the lower the percentage per degree Celsius, the better. The temperature of the solar panel is directly associated with its ability to generate electricity. They are tested for their efficiency at 25-degree C. Most solar panels have a temperature coefficient of around -0.3%/degree C to -0.5%/ degree C. But the good part is unless the solar panels are exposed to an exorbitant amount of heat, the decrease in efficiency is likely to be negligible.
Durability of solar panels
The warranty period for solar panels is generally 25 years.
However, if you find the warranty anywhere less than that then probably the quality of the product is compromised. So, you have to be cautious about that. In addition to that, it is very important to properly maintain solar panels to extend their service life. Fortunately, they are easy to care for and do not require a lot of maintenance.
Certifications of PV modules
The Ministry of New and Renewable energy of India governs the sale and production of solar panels in the country.
Regardless of the type selected, you should consider if you have the authentication required for the purchased product. All crystalline silicon modules must meet the requirements of IEC 61215/14286 and IEC 61730.
In India there are around 300 sunny days, and the total potential solar power generation capacity is about 5 trillion kilowatt-hours / year. As electricity bills skyrocket every day and traditional fuel sources are consumed at an unprecedented rate, our minds should naturally turn to the enormous power hovering above us, sending nearly 1050 W / m2 of energy to the surface of the earth in the form of radiation.
Even a small part can be effectively captured and used for power generation and could cater the growing demands of the country as well and could keep a check in the carbon emission to a large extent. Therefore, the need for solar panels is very obvious. The initial cost of the entire solar kit plays a vital role in the decision-making process, so your choice should be such that you can get the most out of the solar installation.
