How does it work?

Solar panels, also known as photovoltaic (PV) panels are made of thin slivers of silicon coated in plastic and

sandwiched between layers of glass.  When sunlight hits the panel, direct current (DC) electricity is produced.  This DC current then passes through an inverter which converts it into conventional 240 volts AC to be used by your household appliances or fed back into the grid.
