Generate free, green electricity from sunlight using Solar panel systems, also known as solar photovoltaics (PV), capture the sun’s energy using photovoltaic cells. These cells don’t need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.
The benefits of solar electricity
PV cells are made from 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. Groups of cells are mounted together in panels or modules that can be mounted on your roof.

The power of a PV cell is measured in kilowatts peak (kWp). That’s the rate at which it generates energy at peak performance in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes. Most PV systems are made up of panels that fit on top of an existing roof.
The average domestic solar PV system is 3.5 to 4kWp and costs around £7,000 (including VAT at 5%), with the typical cost ranging from £5,500 to £9,500.
Costs have fallen significantly over the last year and vary between products and complexity of the installation.
Other factors that affect PV installation costs are:

A 4.0kWp system can generate around 3,800 kilowatt hours of electricity a year – about three quarters of a typical household’s electricity needs. It will save over a tonne of carbon dioxide every year.
If dust, debris, snow or bird droppings are a problem they should be removed with warm water (and perhaps some washing-up liquid or something similar) and a brush or a high-pressure hose (or telescopic cleaning pole) if the panels are difficult to reach.
Always be careful if you are working above the ground or near the top of a ladder.
