What is an REC?
REC stands for Renewable Energy Certificate. Every time your system produces 1000 kWh, you are awarded an REC. The REC is a legal document that certifies that you have used 1000 kWh of renewable electricity. These certificates are saleable on an open market. Utility companies and private companies purchase these certificates, creating another source of subsidy for solar power. 11. What is net metering? Net metering is the process used in which the utility company “buys back” your solar power. A special meter is installed that measures both how much power you are using and producing. You get charged the difference between the two by your electric company. Net metering is a state law in PA, NJ, and DE, so the power companies are required to buy back your power.
