Due to its favourable geographical position, India is one of the world’s major solar energy generators. Every year, the nation receives tropical sunshine and enjoys clear skies for up to 300 days.
Solar energy is used to generate electricity in photovoltaic solar panels. Solar energy is converted into direct current by the semiconductor cells that make them up. The collected energy is then converted into alternating current by a solar product known as an inverter.
An inverter converts this to alternating current for resale to the network or self-consumption
The photovoltaic panels produce the electricity when they capture the sunlight. The cells that compose them transform solar energy into direct current. This is transformed into alternating current by an inverter for resale to the grid or for self-consumption.
In solar voltaic cells, there are two sorts of technology used. Solar cells are often made of crystalline silicon, which is an efficient and dependable material. According to studies, crystalline silicon is by far the most popular material on the planet, accounting for more than half of the solar industry. Thin film solar cells are the second type of technology and are classified as solar cells in the second category.
This is partly owing to the lower cost of crystalline silicon’s manufacturing method, as well as the fact that thin-film solar cells have historically performed poorly. However, recent research has revealed that thin-film solar cells currently outperform crystalline silicon cells in terms of efficiency.
Superimposition method to install Solar Panels
The solar panels are installed as an overlay on top of an existing roof covering (tiles, slates, zinc, etc.) This is the most often used approach.
The installer does this by relocating some tiles in order to secure hooks in the frame. Aluminum rails will be fastened to these hooks and will act as a support for the panels that will be screwed to them.
The following are some of the advantages of this method:
Because the panels are installed above your roof, there is a gap between the solar collectors and your roof. This area allows air to flow and keep your panels at the proper temperature. Who claims that vented panels equal higher performance?
Because the superimposition process does not contact the roof, it is feasible to keep the roof watertight.
In the summer, overlaying helps to keep a house cool. Indeed, because the tiles are shielded by your overlaid panels, they will be less heated by the sun’s rays, allowing your home to remain cool. Of course, the greater your panel area, the stronger this impact will be.
The condition of the roof should be properly evaluated before to Solar panel systems installation. If your roof is old or damaged, the installation will not last as long as it should. If this is the case, the first thing you should do is fix the roof. Installing a rooftop solar panel initially and then uninstalling it for roof repairs after a few years is pointless. You’ll have to pay more for disassembly and re-installation this method. You should also check to see if your roof has adequate room to sustain the installation. It should also be shade-free during the day so that the maximum amount of sunlight may be captured.
The effectiveness of solar panels is largely determined by the slope of a roof. In addition, the slope is required to assist water drainage during the rainy season. A roof that faces north is ideal since rooftop solar panels put on such a roof will generate the most power. In addition, the roof’s slope should be between 10 and 30 degrees to allow for appropriate rainwater drainage and debris removal.
