Solar in New Haven: What Homeowners Should Know
New Haven sees an average of 4.2 peak sun hours per day, which is what ultimately determines how much electricity a rooftop system produces here. A standard 8 kW system (about 20 panels) generates roughly 9,811 kWh each year in New Haven — and paired with Connecticut's local electricity rate of $0.238/kWh, that's where the savings come from.
At those numbers, a New Haven homeowner saves about $195/month ($2,335/year). Against a $28,800 system cost (about $27,300 after Connecticut state incentives), that works out to a payback of about 11.7 years, after which the system produces essentially free power for two decades — an estimated $52,461 in lifetime savings. Note: the 30% federal tax credit expired at the end of 2025 for purchased systems, though a solar lease or PPA can still pass it through. The local grid is served by United Illuminating, whose net metering policy directly affects how much credit you earn for surplus power.
