Surprise is one of the fastest-growing cities in Arizona and a strong solar market, with wide lots, newer construction, and excellent sun exposure in the far northwest Valley. Surprise is served by APS. Many homes in Surprise were built after 2000 and have modern electrical panels and roofs well-suited for solar installation with minimal prep work. The average Surprise home needs a 12–14 kW system at a cost of $26,000–$30,000 before the 30% federal tax credit. After incentives, typical net cost is $18,000–$21,000 with a payback period of 7–9 years. APS pays avoided-cost export rates for surplus solar — to maximize your return, your system should be sized to cover your annual usage rather than significantly overproduce. Surprise also has a growing number of active adult communities (Sun City Grand, Marley Park) where solar adoption has been particularly high due to higher daytime electricity usage from residents who are home more often.
