Photovoltaic Systems

Solar electricity systems capture the sun's energy using photovoltaic (PV) cells. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting. Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam.  PV cells do not need direct sunlight to work - you can still generate some electricity on a cloudy day.

There are many competing technologies, including 14 types of photovoltaic cells, such as thin film, mono crystalline silicon, polycrystalline silicon, and amorphous cells, as well as multiple types of concentrating solar power. It is too early to know which technology will become dominant.
