Solar in West Valley City: What Homeowners Should Know
West Valley City sees an average of 6.1 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 14,250 kWh each year in West Valley City — and paired with Utah's local electricity rate of $0.110/kWh, that's where the savings come from.
At those numbers, a West Valley City homeowner saves about $131/month ($1,567/year). Against a $22,800 system cost, that works out to a payback of about 14.5 years, after which the system produces essentially free power for two decades — an estimated $30,741 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 Rocky Mountain Power, whose net metering policy directly affects how much credit you earn for surplus power.
