Solar photovoltaic (PV) panels are made up using photovoltaic cells that capture solar radiation (energy) from the sun and covert it into electricity. The cells are set between semi-conducting materials, usually silicon. When light shines on the material it becomes energised and creates a flow of electricity. The solar cells don’t need direct sunlight to generate electricity as they react to visible light therefore allowing them to work even on cloudy days.

The electricity must then pass through an inverter to make it suitable for use in the home. The solar cells initially generate a DC current (direct current) which must be converted to an AC current (alternating current) before being useable. The inverter is normally positioned inside your home and as close to the solar panels as possible, such as the loft or garage. Micro inverters are also available and tuck beneath each solar panel.
