How does it work?

But putting Solar PV (Photovoltaic) panels on your roof, you can generate electricity from daylight – solar power. When light shines on the panels it creates voltage and this in turn is what creates the current which flows along a wire and causes the transmittance of electromagnetic energy. The more light that shines on the panel each year, the more electricity it produces.

An inverter converts the electricity from DC to AC for use in the home. When the solar electricity system is producing more solar power than is needed within the home it is exported to the grid and you receive money from your electricity company. At night, when the solar power system is not producing any electricity, or at a time when more electricity is required within the home than is being produced by the solar system, electricity is imported from the grid in the normal way.
