Residential Solar Investment Program (RSIP)

Through the Residential Solar Investment Program (RSIP), the Connecticut Green Bank, in partnership with a network of contractors and inspectors, has helped more than 46,300 households access solar energy since 2012, surpassing the statutory target of 350 MW (reaching 378 MW) one year ahead of the December 2022 deadline.

1. RSIP provided rebates and incentives to make rooftop solar more affordable for homeowners.
2. When panels produce electricity, they save money and create Solar Home Renewable Energy Credits (SHRECs).
3. Utilities entered into Master Purchase Agreements (MPAs) with the Green Bank to buy SHRECs to comply with policy programs.
4. Green bonds are created via SHREC revenue and purchased by both individual and institutional buyers.
5. Revenue from MPAs and Green Bonds support RSIP incentives and cover administrative costs.
