Solar in Connecticut.
Buy-all/sell-all solar tariff for 20 years.
Your rate nearly doubled in 15 years.
Connecticut's residential electric rate climbed from 18.7¢/kWh in 2010 to 32¢/kWh by 2025. A typical 8 kW rooftop solar system locks your rate well below half of today's grid price for the 30-year life of the array.
What an 8 kW solar install actually pays back.
An 8 kW rooftop array on a Hartford home generates ~9,600 kWh/yr. With Connecticut sales tax exemption (6.35%) and property tax exemption stacked, the system locks your effective electric rate near 8¢/kWh for 30 years. RRES locks the buy-all rate for 20 years; net metering credits at retail.

From first call to permission to operate.
A typical Connecticut residential solar install runs 10–14 weeks from site survey to grid interconnection. Permitting and inspection sit on most of that runway.
The honest FAQ.
Actual questions that come up in the first installer conversation, answered for a typical Connecticut homeowner in 2026.
What's the Solar Energy Adjustment line in the worked example?
Connecticut utilities collect a Solar Energy Adjustment charge ($0.0402/kWh) on net-metered solar exports. It funds the public-benefits portion of the grid that solar customers no longer pay through their kWh bill. For an 8 kW residential array exporting about 9,600 kWh/yr, the SEA totals roughly $385/yr or $7,700 over the 20-year RRES contract. We subtract it in the worked example so the "net benefit" number is honest. Your installer factors the SEA into the payback model at quote time.
Should I pick RRES or net metering?
RRES works best if your daytime energy usage is low and you want predictable monthly payments. Net metering works best if you have high daytime usage. Your contractor will model both.
