Sunlight is one of the Earth's most abundant resources. It can be used to generate power both commercially and for residences. A photovoltaic system captures the energy produced by solar rays and stores the energy within their cells. This energy is converted into electricity and heating. The amount of solar energy that can be used depends largely on geographical location, the season, and time of day.
Solar power accounts for 2.8% of the energy generated in the U.S.
