Helping households in Scotland install energy saving technology 

Solar PV

Solar PV (Solar Photovoltaics) is the generation of electricity using energy from the sun. Modern solar panels produce electricity from daylight and do not require direct sunlight, although more electricity is produced on bright, sunny days.

How does Solar PV work?

Solar PV panels are normally mounted on the roof of your building although they can also be placed on the ground when a suitable roof is not available.

A device called an inverter changes the DC electricity produced by the panels into ‘useable’ electricity that can then be used to power appliances in your home or can be fed back into the National Grid.

Photovoltaic solar systems use cells, consisting of one or two layers of semi-conducting material, to convert solar radiation into electricity. The semi-conducting material is generally silicon, which is the second most abundant element on earth after oxygen.
Light shines on the cell creating an electric field across the layers, this causes electrons to flow, therefore creating electricity.

Solar PV is not only environmentally friendly, but it also reduces the electric bill, whilst giving you complete energy independence.
