Net Metering
Under net metering, the solar power your system produces, offsets the grid power that you use. The meter runs forwards when you use electricity and backwards when you generate electricity, and at a predetermined “true up” period, your electric utility then credits you back for the kilowatt-hours your solar system generates, reducing your electric bill.
With net metering, the solar panels are offsetting the kilowatt use of the home on which they are installed and the state will pay full retail value per watt to the homeowner; the system works using one meter that can count up and down as electricity is produced or consumed.
