How does it work?
Solar PV is a renewable energy system which uses PV modules on the roof of a building to convert light into electricity. PV module cells are made up of thin layers of semi-conducting material which generate an electrical charge when exposed to daylight. When light hits the cells, it creates an electric field across the layers, producing a direct current – that is called photovoltaic effect. This direct current (DC) is then fed into an inverter, which changes it into usable alternating current AC (AC electricity comes from the National Grid) and is either consumed by the household or sold back to the National Grid.
Although Solar PV systems work better in direct sunlight, they are not reliant on it. They need only daylight to generate electricity. However, the location of the PV is important. They should receive the maximum amount of daylight possible, so it’s not advised to install PV panels where trees or surrounding buildings may cast shadows.

We can install solar PV arrays on tiled, slated, corrugated or flat roofs as well as ground mounted systems. Get in touch today to discuss your requirements.
