Solar in St. George: What Homeowners Should Know
St. George sees an average of 6.4 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 14,950 kWh each year in St. George — and paired with Utah's local electricity rate of $0.114/kWh, that's where the savings come from.
At those numbers, a St. George homeowner saves about $142/month ($1,704/year). Against a $22,800 system cost, that works out to a payback of about 13.4 years, after which the system produces essentially free power for two decades — an estimated $35,417 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 Dixie Power, whose net metering policy directly affects how much credit you earn for surplus power.
