How it Works

How Does a Solar Panel Convert Light to Electricity?

Similar to Photosynthesis, where plants use sunlight for growth, Photovoltaics work when light hits the silicon in a PV cell. A cell consists of 2 thin layers of silicon each being ‘doped’ using positive and negative elements’. These are ‘excited’ when the sun’s rays hit, resulting in a flow of electrons which produces electricity.

The electricity flows to an inverter which converts it from Direct Current (DC) to Alternating Current (AC) and carries on into your buildings electricity system. The electricity generated by your system supplies power to your building. If during the day you generate more electricity than you use, this excess will flow back to the grid.

Europe currently represents the largest Solar PV market in the world, but even here the deployment of renewable technologies has barely scratched the surface of the potential.
