Solar panel electricity systems, also known as solar photovoltaics (PV), capture the sun’s energy using photovoltaic cells. These cells don’t need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, dependant on system size and irradiance¬†your PV system could provide free electricity for your own energy consumption. Excess energy is fed back into the grid for an additional export payment.

PV cells are made from layers of semi-conducting material, usually silicon. When light shines on the cell it generates an electric current across the layers. The stronger the sunshine, the more electricity is produced. A PV system is made up of panels or modules are called an array.

The power of a PV array is measured in kilowatts peak (kWp). That’s the rate at which it generates energy at peak performance in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes. Most PV systems are made up of panels that fit on top of an existing roof, but you can also fit solar tiles or ground mounted systems. This technology can also be used in larger scale commercial or industrial applications.

We are now also certified installers for Tesla Powerwall, an efficient way of storing excess energy produced by your PV array. Find out more, contact us now to discover how we can put this new technology to work for you.
