Photovoltaic solar panels are usually made from silicon or other layers of semi-conducting material. When light shines on the cell it creates an electric field across the layers. Electrons are passed from the negative to the positive layer of cells. This movement of electrons generates electricity for your home.

Groups of cells are mounted together in panels or modules that can be mounted on your roof. The stronger the sunshine, the more electricity is produced.

The most efficient (and most expensive) PV solar panels are cut from a single silicon crystal, while the more common polycrystalline PV panels are constructed from a number of crystals.

The latest type of PV solar panel is the 'amorphous' panel, cut so thin as to retain flexibility for easier siting. Currently, the efficiency of solar panels averages around 20% - but this is markedly higher than at the turn of the century, so it can be expected to increase again as technology improves.
