From Solar Energy
Solar PV is a renewable energy system that uses photovoltaic modules on the roof or facade of a building to convert light into electricity. Voltaic cells are made up of thin layers of semi-conducting material which generate an electrical charge when exposed to direct light.

The panel area required to produce an output of 1 kilowatts peak (kWp) typically has an area of around 7m2, produces an annual electricity output of 830 kWh and results in a reduction in CO2 emissions of 471 kg.
The location of solar PV modules is very important because of their sensitivity to the intensity of light and they should ideally be installed on a south-facing roof. Due south is preferable for maximum efficiency. The angle of tilt should be between 25° and 40°, depending on latitude.
