Photovoltaic solar panels : The solar panels convert sunlight into Direct Current (DC) electricity.
Inverter : An Inverter then converts the DC electricity into 240-volt Alternating Current (AC) electricity suitable to power appliances in your house.
Power for your home : Your home uses electricity firstly from the solar panels. If your electricity use is higher than the supply available from the panels, your system gets the extra power from the electricity network.
Monitoring usage : A meter is used to monitor the electricity used from the electricity network as well as the electricity your house supplies to the network.
Excess energy : If your solar panel system produces more electricity than you use, the excess electricity is exported to the electricity network.
