A Renewable Energy credit (REC), or in some states it is called an SREC (Solar Renewable Energy Certificate), is a tradeable certificate that represents all the clean energy benefits of energy generated from a solar energy (or renewable energy) system. Each time a solar energy system generates a certain level of energy, a REC (or SREC) may be issued. This can then be sold or traded separately from the power. This makes it easy for individuals and businesses to finance and invest in clean, emission free solar power. The value of a REC is usually set by a competitive, market-driven, trade and values will vary with market conditions. There may also be restrictions on when a REC will be issued, who owns it and how and when it can be traded. The values provided by this Estimator are based upon known general market conditions. Please refer to your utility, state energy office and/or public utility commission for more details.
