An SREC is a Solar Renewable Energy Credit that is produced for every 1000 kWh (1 MWh) of production your Solar System generates. They are production-based incentives that represent the green attributes produced by your solar project. These SRECs are state incentivized credits that can become a passive income for the solar system owners. Any size system is eligible to participate in SREC selling.

This depends on market prices and the state you live. Please submit your information via our “SREC Quote” form and we will send a pricing for your system.

We offer aggregation services for all types of businesses including non profit, and house of worship.
