Solar Electricity / Photovoltaic

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. PV cells don't need direct sunlight to work - you can still generate some electricity on a cloudy day.

PV cells are panels you can attach to your roof or walls. Each cell is made from one or two layers of semi conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced.
