Homeowners with a sizable PV system connected to the utility grid reduce the amount of electricity they purchase from the utility each month. When more electricity than the PV array is generating is required, the excess can be fed (or sold) back to the utility through net metering. When less electricity than the PV array is generating is required, the need is automatically met by utility power. At the end of the month, a credit for electricity sold is deducted from charges for electricity purchased.
