Connecticut RRES Buy-All

Connecticut pairs some of the most expensive electricity in the country with a solar tariff that pays you for every kilowatt-hour your panels make, and that combination shapes every number in this guide. Panels run $2.68-$2.80 a watt, a typical 9.52 kW system costs about $26,656 before incentives, and the state gets modest sun — about 1,294 kilowatt-hours a year from every installed kilowatt. What the panels earn is governed by the Residential Renewable Energy Solutions program, which replaced traditional net metering in 2022: pick Buy-All and every kilowatt-hour sells at a fixed 32.89 cents for 20 years, or pick Netting and exports earn the retail rate minus a 4.02-cent charge on all production. There is no state income tax credit and no utility rebate, the 30% federal credit is $0 for a homeowner-owned system installed in 2026, and the two tax exemptions Connecticut does offer — no sales tax and no added property tax — are worth about $1,693 on the typical system. Payback lands near 6.6 years on Buy-All at Eversource and around 9.8 years on Netting, with United Illuminating in between. Every size gets priced here, the four big cities get compared, the tariff choice gets worked through in full, and the guide finishes by naming the households that still come out ahead in Connecticut — and the ones that should wait.
