Chandler sits at the crossroads of two major Arizona utility territories: the western part of the city is served by APS, while eastern Chandler — including much of the Ocotillo area — falls under SRP. If you’re not sure which utility serves your home, check your electricity bill or look up your address on each utility’s website before getting solar quotes. Chandler is a strong solar market regardless of utility — the city averages over 299 sunny days a year and 6.5 peak sun hours daily. A typical Chandler home requires a 12–13 kW system, costing $25,000–$29,000 before the 30% federal tax credit. Chandler’s booming tech industry and high household incomes have made it one of the most active solar adoption markets in the Phoenix metro. Arizona also exempts solar installations from sales tax and property tax assessments, keeping your total cost of ownership low. All installers listed here are ROC-licensed and verified active.
