Smart-E loans
Administered by CT Green Bank in partnership with Energize Connecticut
Smart-E Loans offer Connecticut homeowners no-money-down, fixed-rate financing for over 90 energy and home improvements—including solar, heat pumps, insulation, windows, and resilience upgrades—with loan terms from 5 to 15 years at rates starting at 6.99% APR. To get started, obtain quotes from participating contractors, apply for pre-approval directly with a local Smart-E lender, and once approved, your contractor submits the project for technical review before installation and final payment.
Smart-E Loans help your customers finance substantial projects up to $50,000 with low interest rates and fixed terms, expanding your addressable market. You must be on the program's participating contractor list, submit eligible measure documentation for Green Bank technical approval before work begins, and follow the staged payment process: initial one-third upon loan closing, final two-thirds upon Certificate of Completion once the project is finished and the homeowner approves.
Connecticut Green Bank administers Smart-E Loans through partnerships with community banks and credit unions, offering fixed-rate financing (6.99%–7.99% APR depending on term) to owner-occupants of 1–4 unit residential buildings in Connecticut. The program funds over 90 eligible energy efficiency, renewable energy, resilience, and health/safety measures up to $50,000 per loan, with technical underwriting performed by Green Bank staff and final credit decisions by participating lenders based on standard factors including credit score and debt-to-income ratio.
