Solar panels and the inverter are the main two components of the solar PV system. As mentioned earlier, solar panels convert sunlight into electricity in the form of DC.
A 100 kW solar PV system is installed for $4 per Watt. The figures below show an estimated energy output, simple payback period, internal rate of return, and net present value for the 30 years of the
