What is an SREC? Solar Renewable Energy Certificates (SRECs) are a solar incentive that allows homeowners to sell certificates to their utility. A homeowner will earn one SREC for every 1000 kilowatt hours (kWhs) produced by their solar panel system. An SREC can be worth as much as $300 in certain markets. SRECs exist as a result of a regulation known as the renewable portfolio standard (RPS).
