$$ SRECs are tradable, non-tangible energy commodities in the United States that represent proof that 1 Megawatt-hour (MWh) was generated from your system.
$$ They are worth about $250-650 + depending on what state you are in.
1 SREC = 1,000 KWh of solar electricity = 1 MWh of solar electricity produced
10 KWp solar capacity = approximately 12 SRECs per year.
