Net Metering refers to the way an electric utility compensates for excess electricity pushed back to the grid from a solar array. Under Net Metering, a 1:1 credit is created for each kWh you send back to the grid. At the end of the billing cycle, the number of kWh’s delivered by the utility is reduced by the total amount of kWh’s sent back to the grid. Net Metering essentially means the utility pays the full “retail” rate for electricity they could have purchased for much less.
