REC (Renewable Energy Certificate)
A tradeable certificate representing the environmental attributes of 1 MWh of renewable electricity generated. Utilities buy RECs to meet clean energy mandates.
Why It Matters
RECs create an additional revenue stream for solar owners and are the mechanism states use to track and enforce renewable energy goals.
Real-World Example
In states with an SREC market, a 10 kW system producing 12 MWh/year earns 12 RECs. If RECs trade at $30 each, that's an extra $360/year.
