Home Power Systems
A valuable feature of grid-tie or grid-connected photovoltaic systems is the ability to connect with the existing power grid and sell excessive electricity back to the utility with a plan known as Net Metering. At times when you are not using all of the electricity produced by your system, your meter will spin backwards selling the electricity back to the grid at retail rate. These systems do not include a battery. Power is obtained from the utility grid when the system is not producing electricity.
