A Solar PV system uses a series of Photovoltaic cells in a panel to convert daylight into electricity.The PV cell consists of two charged layers in fine balance within a semi conductive material, usually silicon.

When light shines on the cell it disrupts this balance causing electrons to flow between these two layers generating an electricial current.The greater the intensity of light, the greater the flow of electricity.

Solar PV cells are referred to in terms of the amount of power they generate under industry standard conditions known as kilowatt peak (kWp).

In the UK for every kWp of Solar PV installed it generates on average 850 kilowatt hours (kWh) or units of electricity per annum.
