How this tax credit layers inside Arizona's deep stack

The AZ Residential Solar Tax Credit is a state-level credit against what you owe, tracked as one of Arizona's solar incentives in the DSIRE registry. Eligibility is scoped to residential customers, with a stated benefit of 25% of cost, max $1,000. DSIRE lists no scheduled sunset, though enabling legislation and appropriations can still be revised year to year.

That baseline is slower than most states, which raises the stakes for every incentive on the table. Arizona averages 6.5 kWh/m²/day of usable sunlight and residential rates of 13.5¢/kWh, producing an estimated 11,388 kWh/year and $1,537 of annual utility offset on a typical 6 kW system costing $15,900. That baseline already implies a 10.3-year simple payback and a 25-year modeled net of roughly $22,525 before this incentive - every dollar this tax credit delivers compresses that payback further.

Arizona bundles a deep incentive stack, so this program rarely stands alone. Arizona has 5 solar incentive programs indexed in DSIRE, including adjacent options like AZ Solar Property Tax Exemption, AZ Net Energy Metering, APS Renewable Energy Incentive Program. The state's net-metering policy is classified as full, which governs how excess generation is credited and often decides whether a given program is worth claiming for a specific household.
