Connecticut pays roughly 30 percent more for electricity than the national average, and it replaced old-style net metering with a program that gives homeowners a real choice. Here is how the 2026 landscape works, without the recycled 2022 sales pitch.
Connecticut’s RES program, run through Eversource and United Illuminating, gives residential solar two enrollment options with terms locked for 20 years, which is exceptional program stability.
Path one is the Netting tariff: you use your own production first, and surplus exported to the grid earns credit, classic self-consumption economics with long-term certainty. Path two is the Buy-All tariff: every kilowatt hour your system produces is sold to the utility at a fixed rate, as pure production income, while you keep buying your household power normally. Buy-All can suit specific situations, but note that your home does not consume the solar directly and battery backup does not pair with it.
Which path wins depends on your usage, your roof and current tariff rates. We model both and show you the 20-year comparison in writing.
The Connecticut Green Bank backs residential clean energy with financing programs, including Smart-E loans through participating local lenders, and initiatives aimed at making solar accessible for low and moderate income households. Availability and terms vary by program and lender, so we confirm the current options that fit your situation during the assessment.
Solar equipment is exempt from Connecticut’s 6.35 percent sales tax, and residential renewable systems are exempt from property tax assessment, so the value your system adds does not raise your property taxes. Both benefits are structural rather than cycle-dependent.
The federal residential solar tax credit ended for systems placed in service after 2025. Connecticut’s case in 2026 rests on what is real: very high utility rates, a 20-year locked RES tariff either way you choose, Green Bank financing support and two tax exemptions.
That is a strong hand. It just is not the hand from the old brochures, and we think you deserve the current one.
