How it works
Photovoltaic (PV) systems operate using a principle known as the photovoltaic effect. This effect allows the solar PV panels to directly convert solar radiation into electricity.
The solar PV panels collect the sunlight and turn it into electricity.
The electricity reaches the inverter where it is changed into a compatible format.
The electricity is used within the building. Any unused electricity is exported to the grid and earns a credit with the utility.
The meter keeps track of electricity used in the building and produced from the panels and it also tracks electricity used from the grid. This is called net metering.
