Solar Structure

To calculate your solar ROI, first, subtract what you spent initially from how much you’ll save over the lifetime of your solar system. Then, divide this by your initial investment, and multiply by 100 to get the percentage. Keep in mind that grid power costs might continue to rise, enhancing your ROI with each year possibly.

As per the policies, most states allow consumers to install rooftop solar of capacities that are upto the total capacity of your meter. For example if your meter has a capacity of 3 KW, you are allowed to install rooftop solar only upto 3 Kw. In case you want to install a 4 KW rooftop solar, you first need to increase your electricity meter capacity upto 4 KW before applying for rooftop solar.

A rooftop solar system comprises of solar panels, inverters, net-meters, solar structures, earthing wires, connecting wires, lightening arresters and others. These are mandatory parts needed in the system. So it is not the solar panel alone but a whole range of other items too that make the whole system.
