Connecticut Residential Solar Incentives

Solar energy is sustainable, renewable, and plentiful which is why many homeowners choose to install solar panels to generate electricity.

Residential Renewable Energy Solutions (RRES) is a program that gives you the opportunity to sell the power you generate with your residential solar installation and any renewable energy certificates (RECs) to us.

Note: Customers who installed solar before January 1, 2022, are participating in the Net Metering Program.
