Peoria is one of the fastest-growing cities in the Phoenix West Valley and is served by APS. With a mix of established neighborhoods, master-planned communities like Vistancia and Westwing Mountain, and a high proportion of single-story homes with large roof areas, Peoria is an excellent solar market. The average Peoria homeowner needs a 12–14 kW system at a cost of $26,000–$30,000 before incentives. After the 30% federal tax credit, net cost is approximately $18,000–$21,000. APS credits exported solar at its avoided-cost rate — to maximize savings, most Peoria installers will size your system to cover roughly 90–100% of your annual usage rather than generating a large surplus. Arizona offers additional incentives including a 25% state income tax credit (capped at $1,000) and a full property tax exemption on the added home value from solar. All solar contractors on this page are verified active with the Arizona Registrar of Contractors.
