In the same way as the sun can power anything from a pocket calculator to garden lighting it can also be used to feed the electrical system in your home.

Photo Voltaic (PV) cells capture the suns rays and convert them into DC electricity which is the same type of power as found in regular batteries.

An inverter converts the DC power into AC power which is the same as fed by the electricity supplier.

This free energy can then be used instead of your regular supply. Any excess energy will be fed back into and paid for by the national grid, not only saving you money but earning it too.
