How Solar PV Works

Solar panels produce clean green electricity for millions of people around the world. They are a simple technology with no moving parts, producing no emissions, no noise and a very long lifetime.

Some pictures to illustrate our work.
VanImageVanImageThe Solar Panels use ‘photovoltaic’ cells to turn the sun’s energy in electricity. Photovoltaic modules can be black or dark blue. The PV cell consists of one or two layers of a semi conducting material, usually silicon, which tends to be recycled from other industry waste. When light shines on the cell it creates an electric field across the layers causing electricity to flow. The greater the intensity of the light, the greater the flow of electricity. The sunnier it is, the more electricity your panels produce. However, even on cloudy days the panels will still produce useful electricity.

The electricity used in the vast majority of domestic and commercial premises is known as AC (Alternating Current). The electricity produced by PV modules is the other sort; DC (Direct Current). Apiece of equipment called an inverter, changes DC into AC.

The electricity is then fed through a generation meter and into your fuse board(Consumer Unit). From there it goes into your business or home electric system in the same way as your other electricity. The generation meter is critical because it tells you how much electricity you are generating and therefore how much you can earn from your system.

When your panels are producing electricity, your business will automatically use the solar power produced. When they are not producing electricity (for example at night) you will get your electricity the old-fashioned way (from the grid). This all happens automatically. On a really sunny day for example you might want to get all your washing done to make the most of all the clean green electricity that you are producing.

If you generate more electricity than you can use at that time then the surplus goes back into the grid for other people to use. This is great as it means that over time more and more of the country’s electricity comes from renewable power.
