How much rooftop area is required for solar PV installation?

We assumed that the estimated building footprint is representative of the available rooftop area in each FN i.e., 100% of the estimated rooftop is available for solar panel installation. To install 1 kWp of roof-mounted solar PV, 10 m 2 of rooftop area is required, which is in line with the thin film technology currently in use.
