Solar in Lowell: What Homeowners Should Know
Lowell 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 Lowell — and paired with Massachusetts's local electricity rate of $0.278/kWh, that's where the savings come from.
At those numbers, a Lowell homeowner saves about $227/month ($2,728/year). Against a $28,000 system cost (about $27,000 after Massachusetts state incentives), that works out to a payback of about 9.9 years, after which the system produces essentially free power for two decades — an estimated $66,166 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 Eversource MA, whose net metering policy directly affects how much credit you earn for surplus power.
