Solar Electric
Solar PV (photovoltaic) uses energy from the sun to create electricity to run appliances and lighting. PV systems work on daylight, and even more efficiently with direct sunlight, to generate electricity.
Photovoltaic systems use cells to convert solar radiation into electricity. The PV cell consists of one or two layers of a semi conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers, causing electricity to flow.
Whilst they are far less efficient than solar hot water panels, they are becoming more widely used as costs are starting to come down, grants are available and production is increasing.
PV systems generate no greenhouse gases, saving approximately 325kg of carbon dioxide emissions per year - adding up to about 8 tonnes over a system's lifetime - for each kilowatt peak (kWp - PV cells are referred to in terms of the amount of energy they generate in full sun light).
