Solar (PV) Electricity

Solar Panels & Solar Electricity

Generate cheap, green electricity from sunlight.

Solar electricity systems capture the sun’s energy using photovoltaic (PV) cells. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting. PV cells don’t need direct sunlight to work – you can still generate some electricity on a cloudy day..

How do photovoltaic (PV) cells work?

PV cells are panels you can attach to your roof or walls. Each cell is made from one or two layers of semiconducting material, usually silicone. An environmentally friendly resource of which there is NO limitation to its availability. As a raw material silicone is in fact the second most abundant material in the mass of the earth. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced. PV cells come in a variety of shapes and colours, from grey “solar tiles” that look like roof tiles to panels and transparent cells that you can use on conservatories and glass. The strength of a PV cell is measured in kilowatt peak (kWp). That’s the amount of energy the cell generates in full sunlight.

Here is an example of how a Solar Photovoltaic system would work in your home:

Electricity is created by your Solar Photovoltaic (PV) system using the energy from the sun. Your electricity supplier pays you for each unit of electricity you generate. The electricity travels to your inverter. This is necessary because solar PV panels generate DC power, but your house runs off AC power.

Once inverted the electricity is passed to your generator to show how much electricity you are generating and then sent on to your mains consumer unit (fuse-board). Once the electricity is passing through your mains consumer unit it is ready for use to power all of the electrical appliances around your home.

You are using the electricity you have generated meaning you do not have to import from the grid. Your electricity suppliers meter continues to monitor your incoming supply. The surplus electricity is then exported back to the grid where your supplier pays you an export tariff for each unit of electricity you have not used.
