Phoenix is one of the best cities in the country for solar — averaging over 299 sunny days per year and more than 6.5 peak sun hours daily, most residential systems pay for themselves in 7–10 years. The average Phoenix homeowner needs a 13–14 kW system, which costs approximately $28,000–$32,000 before incentives. After the 30% federal solar tax credit, your net cost typically falls between $20,000–$22,000. Phoenix is served by APS (Arizona Public Service), which pays homeowners an avoided-cost export rate for excess solar energy sent to the grid — currently around 2–3 cents per kWh. While lower than full retail net metering, Phoenix’s high sun exposure means most well-sized systems still produce significant savings. All solar installers working in Phoenix must hold an active Arizona ROC license — every company listed here has been verified against the ROC database. Look for the ROC badge on each listing to confirm current standing.
