Although the British weather may be unpredictable, there is still enough radiation from the sun to generate electricity using solar panel systems – otherwise known as Solar Photovoltaics (PV). The cells within the panels do not require direct sunlight and can in fact generate electricity even on a cloudy day. Hr Hislop are Calne electricians who can specify and install domestic solar Phiotovoltaics throughout the local area.
PV cells are made from layers of semi-conducting material – usually silicon. When light shines on the cell it creates an electric field across all of the layers. The stronger the sunshine, the more electricity is produced. Groups of cells are mounted together in panels or modules that can be fitted to your roof or even mounted on the ground.
The power of a PV cell is measured in kilowatts peak (kWp). That is the rate that electricity is generated at peak performance – in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes, although the most popular are the panels mounted on to an existing roof.
A standard 4kWp system can generate around 3,800kw hours of electricity a year in the south of England – that’s enough to power a typical family home.
If your system is eligible for the Feed-in Tariff scheme you could generate savings and receive payments of £610 – £740 per year.
