Complete Guide to Arizona Solar Incentives (2026)

Arizona is one of the most incentive-rich states for solar in the country. Between the federal Investment Tax Credit, Arizona's own state income tax credit, sales and property tax exemptions, and utility buyback programs, a typical homeowner can reduce their net solar cost by 35–40% before considering long-term electricity savings.

This guide covers every incentive available to Arizona homeowners in 2026 — what each one is worth, who qualifies, and how to claim it. For pricing context, see our guide on how much solar panels cost in Arizona. And if you're ready to see your personalized savings estimate, use our Arizona solar calculator.

Federal Solar Investment Tax Credit (ITC) — 30%

The federal ITC is the biggest solar incentive available to any American homeowner. It lets you deduct 30% of your total solar system cost from your federal income taxes — dollar for dollar, not just as a deduction.

What It's Worth

On a typical 8 kW Arizona installation costing $17,040, the 30% ITC equals $5,112 off your federal tax bill. If you add battery storage (which qualifies when charged from solar), the credit applies to the full system cost including the battery.

Key Details

• Applies to the full installed cost: panels, inverters, racking, wiring, labor, permit fees, and battery storage
• Must own your system (not lease) to claim the credit
• You must have sufficient federal tax liability in the year you install — unused credit can carry forward to future years
• Claimed on IRS Form 5695 when you file your taxes
• Credit rate: 30% through 2032, 26% in 2033, 22% in 2034, then expires for residential

Arizona State Solar Tax Credit — 25% (Capped at $1,000)

In addition to the federal credit, Arizona offers its own state income tax credit equal to 25% of system cost, up to $1,000. This credit is claimed on your Arizona state income tax return the year your system is installed.

Key Details

• Maximum credit: $1,000 (reached at a $4,000 system cost)
• Any unused credit can carry forward up to five tax years
• Must be a primary or secondary residence (not rental property)
• You must own — not lease — the system
• Claim on Arizona Form 310

Combined incentive example: On an $17,040 solar system, the 30% federal ITC saves $5,112 and the AZ state credit saves another $1,000 — totaling $6,112 in tax credits alone, bringing your net cost to $10,928.

Arizona Solar Equipment Sales Tax Exemption

Arizona fully exempts solar equipment from the state's 5.6% transaction privilege tax (sales tax). On a $17,040 system, that's nearly $954 in savings you don't have to think about — your installer should already be applying this exemption to your quote.

The exemption covers photovoltaic panels, inverters, racking, wiring, and battery storage when purchased as part of a solar installation. Ask your installer to confirm the exemption is applied on your contract.

Arizona Solar Property Tax Exemption

Arizona's property tax exemption means your home's assessed value — and therefore your property taxes — will not increase due to the addition of solar panels, even though studies consistently show solar adds real market value to homes.

This is particularly valuable in Arizona, where a properly sized solar system typically adds $15,000–$25,000 in home value. Without the exemption, that increase could translate to $150–$300/year in additional property taxes. The exemption applies for as long as you own the home with solar.

Utility Buyback Programs (Net Metering / Net Billing)

Arizona's three main utilities each have programs to credit homeowners for excess solar electricity sent back to the grid. These programs directly affect your monthly bill and your long-term savings — so understanding your utility's specific rates matters.

APS — Arizona Public Service

APS transitioned from true net metering to a "resource comparison proxy" net billing model. In 2026, APS pays approximately $0.068/kWh for excess solar you export — significantly less than the retail rate of ~$0.15/kWh you'd pay for electricity. This makes self-consumption more valuable than exporting. Read our full APS solar buyback rates guide for current rate details and strategies to maximize your bill savings.

SRP — Salt River Project

SRP offers several rate plans for solar customers. The Export Energy Credit program pays approximately $0.065/kWh for exported solar. SRP customers should carefully evaluate which rate plan is most advantageous before going solar. See our SRP solar rate plan comparison for details.

TEP — Tucson Electric Power

TEP's net billing program credits solar exports at approximately $0.057/kWh. Tucson-area homeowners should factor this rate into their payback calculations. Our TEP net billing guide covers everything you need to know.

Key takeaway: Arizona utilities pay less for exported solar than the retail rate you pay to buy power. This means sizing your system to cover your consumption — but not massively overshoot it — is the smartest strategy.

Arizona HOA Solar Rights

Arizona law (ARS § 33-1816 and § 33-439) protects homeowners' rights to install solar, even in HOA communities. HOAs cannot prohibit solar installations — they can only make reasonable aesthetic requirements (like panel placement) that don't significantly impact performance or cost. Learn more in our guide to Arizona HOA solar rights.

How to Maximize Your Arizona Solar Incentives

1. Ensure you have sufficient tax liability to use the federal ITC in year one. If not, consult a tax professional about carry-forward options.
2. Own your system — leases and PPAs don't qualify for the federal or state tax credits.
3. Install in the current tax year — credits are claimed the year installation is complete and the system is energized.
4. Include battery storage in your solar system to qualify for the ITC on that equipment too.
5. Choose your utility's best rate plan for solar production — see our guides for APS and SRP.
6. Work with a tax professional who understands energy credits to ensure accurate filing.

Incentives Summary Table

What's Not Covered: Common Misconceptions

A few things homeowners often expect but won't find in Arizona:

• No Arizona utility rebates: APS, SRP, and TEP have ended their upfront solar rebate programs. Incentive value now comes from tax credits and ongoing bill savings.
• No true net metering: All three major utilities have shifted to net billing models that pay less than retail for exported power.
• Lease and PPA customers miss out: The federal and state tax credits go to the system owner — if you lease, the installer keeps them.
