Solar in Gilbert: What Homeowners Should Know
Gilbert sees an average of 6.6 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 15,418 kWh each year in Gilbert — and paired with Arizona's local electricity rate of $0.142/kWh, that's where the savings come from.
At those numbers, a Gilbert homeowner saves about $182/month ($2,189/year). Against a $21,600 system cost (about $20,600 after Arizona state incentives), that works out to a payback of about 9.4 years, after which the system produces essentially free power for two decades — an estimated $54,182 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 Arizona Public Service, whose net metering policy directly affects how much credit you earn for surplus power.
