How Do I Sell Electricity Back to the Utility Company? |
|
Solar PV systems are tied to the utility grid through inverters. Inverters track kilowatt-hour (kWh) production every day. When a solar system produces more electricity than is used, the inverter sends the surplus energy to the grid, the electric meter spins backwards and the utility credits the owner for the surplus energy at the same retail rate that it charges for electricity during that period. If you’re on an optional Time-of-Use net energy metering schedule, the utility credits your account during peak rate periods at several times off-peak rates. This helps to reduce the size of your solar installation, and can zero out your electric bill over the course of each year.
