Solar Panels Photo Voltaic (Solar PV)

There are 2 types of Solar Panel systems, Photo Voltaic (Solar PV) and Solar Water Heating. Solar PV a system that Utilise the suns solar rays to generate free electricity. It relies on the light rather than the heat to generate power through the photovoltaic cells in the panels on the roof. This means that they work even in winter and also on cloudy days.
