You can use photovoltaic or PV solar panels to generate cheap, green, low carbon electricity from sunlight.
PV cells don’t even need direct sunlight to work – you can still generate some electricity even on a cloudy day.
How do photovoltaic (PV) cells work?
PV cells are panels you can attach to your house. Each cell is made from one or two layers of a semiconducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the light the more electricity is produced.
The strength of a PV cell is measured in kilowatt peak (kWp) – this is the amount of energy the cell generates in bright sunlight.
Making money with PV
It is still possible to be paid for excess electricity produced by your solar (photovoltaic) panels. This payment is called a Feed-in Tariff – learn more about feed-in tariffs on the Energy Saving Trust website.
