Solar in Saco: What Homeowners Should Know
Saco 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 Saco — and paired with Maine's local electricity rate of $0.208/kWh, that's where the savings come from.
At those numbers, a Saco homeowner saves about $166/month ($1,992/year). Against a $27,200 system cost (about $25,200 after Maine state incentives), that works out to a payback of about 12.6 years, after which the system produces essentially free power for two decades — an estimated $42,847 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 Central Maine Power, whose net metering policy directly affects how much credit you earn for surplus power.
