A solar photovoltaic system PV uses sunlight to generate electricity. Within the panels are solar cells
which, when exposed to sunlight, produce direct current (DC) energy. To power the appliances in the home, this
electricity must be converted to alternating current (AC) and this is done by a solar inverter. Once the renewable
electricity has passed through the solar inverter, it's ready to power the electrical items around the home.
PV solar panels arent nearly as efficient as thermal panels, turning about 20% of captured sunlight into electricity
