Is solar worth it in Arizona? (2026 numbers)
For a typical Arizona home with a $158/month electric bill, a 6.9 kW system costs about $17,900 before incentives and saves about $1,430 in year one, paying back in roughly 12 years if you buy it. The federal 25D credit ended for systems installed after 2025, so many Arizona homeowners now compare cash purchase against a lease or PPA.
