A solar PV system uses energy from the sun to generate electricity. It doesn't need sunlight to produce electricity - only daylight, even in winter. So you could be helping to lower your bills by reducing the amount of electricity you need from your supplier.
With solar PV, not only could you save money by generating your own electricity, you could also benefit from the Government's Feed-in Tariff.
solar PV panel consists of cells of one or two layers made from a semi-conducting material like silicon.
When light shines on the cell it creates an electric field across the layers, causing electricity to flow.
The electricity flows through a cable and is collected at a central point often located in your roof space.
The electricity is then converted from a direct current (DC) to an alternating current (AC) and carries on into your home for you to use.
If you don't use all the electricity that you have generated it will be fed into the National Grid automatically.
