Solar Panel Cost in Arizona (2026)
Installed solar in Arizona runs about $2.45 per watt — roughly 5% below the national average of $2.58/W. With the federal residential tax credit (25D) gone as of 2026, payback here rests on a $0.16/kWh power price and 6.5 daily peak sun hours.
Worked example: a typical $150/month home in Arizona
A $150/month electric bill in Arizona works out to about 11,613 kWh a year. Sizing a cash-purchase system to cover 100% of that:

Local context: Among the best sun in the country, but utilities buy back excess at avoided-cost rates well below retail.
Arizona credits exported power at about 70% of the retail rate (NEM 3.0-style), so a battery to store and self-use your generation usually improves the return here.
