Solar photovoltaics (PV)

Solar panels, used to power lighting, on the roof of Brancaster Millennium Activity Centre, Norfolk

Take a look at your neighbour’s roof and you might spot a PV panel. They work on the ground too and can even be integrated into roofs as tiles.

How do they work?

They use the sun’s rays to generate electricity for use at the place that they’re fitted, or to export to the grid.

PV uses solar energy to generate electricity for use on site or export to the grid. Typical energy generation might be around 500 watts per one-metre panel.
