Buckeye is one of Arizona’s fastest-growing cities and is served by APS. Its newer master-planned communities — including Verrado and Tartesso — have modern construction well-suited for solar. Average system size: 12–14 kW, costing $25,000–$29,000 before the 30% federal credit. APS customers in Buckeye export surplus solar at the avoided-cost rate. With very low population density and large lot sizes, Buckeye homes often have among the largest roof areas in the Valley — giving installers more flexibility in panel placement and system design.
