Solar in Warwick: What Homeowners Should Know
Warwick sees an average of 4.1 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 9,578 kWh each year in Warwick — and paired with Rhode Island's local electricity rate of $0.199/kWh, that's where the savings come from.
At those numbers, a Warwick homeowner saves about $159/month ($1,906/year). Against a $28,000 system cost (about $20,500 after Rhode Island state incentives), that works out to a payback of about 10.8 years, after which the system produces essentially free power for two decades — an estimated $44,603 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 National Grid RI, whose net metering policy directly affects how much credit you earn for surplus power.
