There are simple steps for installing a PV system on the rooftop. They are given below:
1.WEIGH YOUR OPTIONS
Before selecting and installing the solar panels in your house, you need to remember a few points. First of all, is there adequate space for installing solar panels on the rooftop? If yes, then how much is it in feet or per square?
Secondly, is it the part of your roof where the sun shines brightly during the hours of daylight? Third, is the roof strong enough structurally to support these panels, and how much will they weigh? Moreover, how much area on your roof is covered mainly by shades?
Lastly, what type of solar panel is perfect for installing at your house, bifacial, PERC, Polycrystalline, monocrystalline, or thin-film?
2. ENERGY AUDIT AND LOAD DIVISION
Now that you have decided upon your choices, the next target is to determine the electricity required when the solar plant has been installed at your house. You can calculate the measures through solar system capacity payback. For the solar system and the area requirement in the solar system.
Now put an estimate for the solar panel electricity needed in the house to be generated, which is done by an energy audit. These audits are helpful to reduce the energy bill without excessive use, predict the solar energy required by the system, and meet the necessary conditions for the loans, rebates, and tax credits.
