There are no moving parts so no user intervention is required in the day-to-day operation of the Solar Photovoltaic (PV) System. It is designed for automatic, unattended operation. When there is sufficient light, either direct or indirect, your PV System generates electricity for use. The energy produced will be consumed by loads.  Any excess electrical energy generated by your PV System will be exported to your local electrical transmission grid. Your local Wires Service Provider (WSP) and electrical retailer will work in conjunction to record (via a bi-directional meter installed for free by your WSP) all exported electrical energy in kWhs where you will be compensated for all net-electrical energy exported.
