Arizona Solar Incentives, Tax Credits & Rebates Guide (2026)

Arizona State Solar Incentives

Arizona offers multiple incentive programs that further reduce the cost of going solar. The primary state-level benefit is Limited incentives.

While Arizona doesn't offer as many state-level incentives as some other states, the federal tax credit remains the most valuable incentive, and solar still makes strong financial sense in Arizona due to higher-than-average electricity rates.

Net Metering in Arizona

Arizona currently has limited net metering policies. This means that excess electricity your panels produce may be credited at a lower rate than the retail price you pay for electricity, or net metering may only be available through certain utilities.

What this means for you:

• You'll still save money on electricity costs when your panels are producing during daylight hours
• Consider adding battery storage to capture excess production for use during peak rate hours or at night
• Size your system to match your daytime consumption rather than overbuilding for excess export to the grid

Even without robust net metering, Arizona households with electricity rates of $0.16/kWh still see strong returns on solar investments, with systems typically paying for themselves in 8-11 years.

Maximizing Incentives with Smart Financing

How you finance your solar system determines which incentives you can claim. The 30% federal tax credit no longer applies to any system you own—whether paid for in cash or with a solar loan. It remains available only through a lease or PPA, where the provider claims it, not you.

Cash Purchase

Paying cash means you own the system outright from day one and qualify for any state or local programs—but not the 30% federal credit, which no longer applies to purchased systems.

• Pros: Highest lifetime savings, no interest charges, immediate ownership
• Cons: Requires significant upfront capital ($24k-$31k for most systems); no federal tax credit

Solar Loans

Solar loans let you own the system while spreading payments over 5-25 years. Because you own the system just as with a cash purchase, the federal tax credit does not apply, though you may still qualify for state or local programs. Many Arizona households find their loan payment is equal to or less than their previous electric bill, meaning they save money from month one.

• Pros: No upfront cost, builds home equity, may qualify for state incentives
• Cons: Interest charges reduce overall savings; no federal tax credit since you own the system

Solar Leases and PPAs

With a lease or Power Purchase Agreement, you don't own the system—a solar company does. That company claims the 30% federal tax credit under Section 48E and typically passes some of that value to you through a lower monthly payment or discounted electricity rate. This is currently the only way a residential customer benefits from the 30% federal credit, since it no longer applies to systems you own.

• Pros: $0 down, no maintenance responsibility, predictable costs, indirect access to the federal credit via the provider
• Cons: You don't own the system, lower lifetime savings, may complicate home sales

Ownership (cash or loan) still tends to deliver better long-term value than leasing in most cases—not because of the federal credit, which no longer applies either way, but because you keep 100% of the electricity savings and any home value increase instead of sharing them with a third-party owner. Run the numbers for your specific situation, since local electricity rates and lease terms vary.

Future Changes to Solar Incentives

Solar incentives have evolved significantly over the past decade, and they'll continue to change:

State Policy Changes

Arizona solar policies can change over time. Net metering rates, state tax credits, and utility rebate programs are all subject to legislative and regulatory changes.

The good news: most policy changes include grandfather clauses that protect existing solar owners. Installing now typically locks you into current favorable rates and policies, even if they become less generous for future installations.

The Bottom Line on Timing

The 30% federal tax credit for purchased systems expired after 2025, and it's unclear whether it will return. What remains in Arizona's current programs and growing electricity rates, which still make solar a reasonable investment for many homeowners—just without the federal boost that used to apply to purchases.
