Solar Renewable Energy Certificates (SRECs) are credits that your solar power system earns for you for each kWh it produces. The credits are earned regardless of how the energy is used, and they are entirely separate from net energy metering credits. The credits can be sold for a profit in areas where SREC markets are active and open.
Unfortunately, SRECs are not available in Louisiana. They’re typically found in states with progressive RPS goals, so they’re not an option in The Pelican State.
