Solar Incentives in Arizona (2026)

Arizona residents installing rooftop solar can combine the 30% federal Investment Tax Credit (ITC) with a state-specific credit (25% state tax credit up to $1,000). Net-metering rules and property/sales tax exemptions are the other big levers.

Gross install cost (6 kW)$15,600
After federal ITC (30%)$10,920

Arizona avg installed cost: $2.60/watt (state avg, 2026). Federal ITC value: $4,680. Additional state incentives (below) may reduce net cost further.

1. Federal Investment Tax Credit (ITC)

Every U.S. state gets the 30% federal ITC. It applies to the gross install cost, including panels, inverters, labor, and permit fees. For a 6.0 kW system in Arizona at $2.60/watt, that’s a credit of $4,680 against your federal income tax. The credit is refundable-carryforward — unused portions roll to future tax years. Valid through 2032.

2. State income-tax credit

25% state tax credit up to $1,000

This stacks on top of the federal credit. Consult a local CPA to confirm current-year limits.

3. Net metering rules in Arizona

Replaced by 'net billing' — exports valued at utility avoided cost (~30-50% of retail)

Net metering determines how much you’re credited for excess solar energy exported to the grid. "1:1" or "full retail" is the best — you get the same rate you pay. "Avoided cost" or "net billing" pays substantially less (often 25-50% of retail).

4. Property & sales tax exemptions

  • Property tax: ✅ Yes — the added home value from solar is excluded from property tax reassessment in Arizona.
  • Sales tax: ✅ Yes — solar equipment is exempt from state sales tax in Arizona, saving typically 5-8% of gross cost.

5. Utility rebates & notes

State income-tax credit + property/sales-tax exemption make AZ solar-friendly despite the net-metering downgrade.

Utility rebates change frequently. Verify current terms with your specific utility (not just "the state") before signing an installer contract.

Bottom line for Arizona

A typical 6.0 kW rooftop system in Arizona costs about $15,600 gross → $10,920 after the federal ITC. With Arizona’s electricity rate of 15.48¢/kWh, this system saves about $1,719/year — paying back in 6.4 years on the federal credit alone. Add the state-level items above and the net cost drops further.

FAQ

Can I combine federal ITC and Arizona’s state incentives?

Yes — the federal ITC and Arizona’s state credit stack independently. However, some utility rebates reduce the "cost basis" the federal ITC applies to. Consult a CPA.

When do I get the federal ITC money?

The ITC reduces your federal income-tax liability for the year the system is placed in service (i.e., commissioned and producing power). If your tax owed is less than the credit, unused portions roll forward. You do not receive a check.

Do rebates and credits get taxed?

Rebates from utilities are generally not taxable (they reduce your cost basis). Federal tax credits are not income. Some state credits may be treated differently — check your state Department of Revenue.
