Learn how solar energy works and save money also- Hudson Solar: "What is Net Metering?
Solar electric generation and purchases from the electric utility are “netted out” automatically. This can slow down the utility’s meter or even spin it backwards if the solar system is producing more electricity than is being consumed. Your excess electricity is then sold back to the utility at the retail rate, per agreement with the utility company.
Most State utilities will permit most customers with fewer than 25 kilowatts of PV to net meter."
