If you researched solar in Arizona a year or two ago, much of what you learned is now out of date. Arizona net metering and solar incentives shifted substantially heading into 2026, at both the federal and state levels. The rules that decide whether a solar system pays off no longer match the older rules. This guide explains what actually applies in Arizona now. It covers how the state compensates solar exports, which incentives still exist, how the major utilities differ, and what a realistic payback picture looks like.
Important: this article offers general information, not financial, tax, or legal advice. Solar incentives, utility rates, and tax rules change, sometimes more than once a year. The details that matter depend on your utility, your municipality, and your individual tax situation. Treat everything here as a starting point. Before making any decision, confirm current terms directly with your utility, your local permitting office, and a qualified tax professional. Figures in this article reflect early 2026 and carry no guarantees.
How Solar Exports Are Compensated in Arizona Now
The single most important thing to grasp is that Arizona no longer offers traditional net metering for new residential solar customers. Under old-style net metering, every kilowatt-hour your panels sent to the grid earned credit at the full retail electricity rate. A kWh exported was worth exactly as much as a kWh you bought. That made solar math simple and the payoff fast.
That era has ended in Arizona. The state moved to a model usually called net billing. Under net billing, your utility credits the electricity you export at a rate it sets. That export rate is lower, often considerably lower, than the retail rate you pay to buy electricity. APS phased out traditional net metering years ago. SRP retired its remaining net metering plans in late 2025, moving new solar customers onto time-of-use net billing.
This shift changes how you should design and value a solar system. A kWh you use directly in your home (offsetting the retail rate) is worth more than a kWh you export. The exported kWh earns credit only at the lower export rate. So a solar system in Arizona delivers the most value when you size and use it to power your own household loads. Air conditioning is a key example. Sending large surpluses to the grid yields less. The practical takeaway: in 2026, Arizona, self-consumption matters. That is also why battery storage now plays a bigger part in the conversation.
The Federal Solar Tax Credit: A Major 2026 Change
For about two decades, the federal government offered a residential solar tax credit, most recently worth 30% of a system’s cost, which homeowners claimed directly. That credit anchored residential solar economics nationwide.
That picture has changed. The One Big Beautiful Bill Act, signed in July 2025, ended the Section 25D Residential Clean Energy Credit for customer-owned systems. EnergySage’s summary of the law notes that the credit fell to zero for owned residential systems installed after December 31, 2025. There was no phase-down period. In plain terms, if you buy a solar system with cash or a loan and install it in 2026, you generally do not receive a federal tax credit.
One remaining federal pathway exists, though it is narrower. Third-party-owned systems, solar leases, and power purchase agreements may still qualify under the separate commercial tax credit. In those cases, a company owns the equipment on your roof. The benefit goes to the system owner, who may or may not pass savings on to you. Homeowners who installed an owned system in 2025 can still claim the old 30% credit on their 2025 tax return. This change matters a great deal. Verify the details with a tax professional for your situation. Older online guidance often predates the change, so do not rely on it.
Arizona State Solar Incentives
While the federal picture changed, Arizona’s own state-level incentives were not affected by the federal law and remain in place. They are more modest than the old federal credit, but they are real.
Arizona State Solar Tax Credit
Arizona offers a state income tax credit for residential solar. Solar United Neighbors describes the credit as 25% of the cost of a solar energy system, capped at $1,000. You claim it on your Arizona state tax return. Most systems reach the $1,000 cap. If your state tax liability falls below the credit in the year you install, you can generally carry the unused portion forward. Arizona Revised Statutes establish this credit. It stands independent of any federal program.
Sales Tax Exemption
Arizona exempts solar energy equipment from the state’s transaction privilege (sales) tax. This applies to the solar equipment itself and means you do not pay the state sales tax rate on that portion of the purchase. The seller generally handles the exemption, so it reduces your cost without a separate application on your part.
Property Tax Exemption
Solar adds value to a home, and normally, that added home value can raise property taxes. Arizona law exempts the added value of a solar energy system from property tax assessment. So installing solar does not increase your property tax bill even though it may lift your home’s market value. This exemption continues over time rather than offering a one-time benefit.
Each of these has specific rules and documentation requirements, and amounts and eligibility can change. Confirm current details with the Arizona Department of Revenue, your county assessor, and a tax professional before relying on a specific figure.
How the Major Arizona Utilities Differ
In Arizona, your utility matters as much as any state policy, because each major utility sets its own export rate and rate structure. The same solar system can show meaningfully different economics depending on who delivers your power.
APS (Arizona Public Service)
APS, the state’s largest utility, compensates solar exports under a mechanism called the Resource Comparison Proxy (RCP). One 2026 guide citing APS rate documentation puts the APS export credit at roughly $0.0617 per kWh. That rate applies to the tranche running September 1, 2025, through August 31, 2026. The figure reflects a scheduled reduction from the prior period. The RCP rate has stepped down over time, and APS applies an annual true-up. Most APS solar customers land on time-of-use rate plans. Export rates follow a schedule of declines. So the rate you start on becomes an important detail to confirm directly with APS.
SRP (Salt River Project)
SRP serves much of the Phoenix metro area as a public power utility. The Arizona Corporation Commission does not regulate it the way it regulates investor-owned utilities. SRP retired its remaining traditional net metering plans in late 2025. New solar customers go onto time-of-use net billing plans. Many observers note SRP rate structures that can include demand charges and fixed monthly charges for solar customers. These charges affect solar economics significantly. SRP customers should contact the utility directly to confirm current plan options, export credit, and any fixed or demand charges. Sizing a system without that information is risky. Battery storage often plays a key role in the discussion for these customers.
TEP (Tucson Electric Power)
TEP serves the Tucson area and also operates under a net billing structure rather than traditional net metering. Export credits vary by time period on time-of-use rates. As with the other utilities, TEP sets the specific rate and plan details and changes them over time.
The common thread: do not assume a friend’s or neighbor’s solar experience applies to you unless you share the same utility and rate plan. Always confirm your own utility’s current terms.
Permitting and Interconnection Basics
Installing a grid-connected solar system in Arizona involves more than the equipment. You need two parallel approvals.
The first is the local building or electrical permit, which your city or county issues. Solar installations must meet electrical and building codes. A permit and inspection form part of any legitimate installation. The second is interconnection approval from your utility. It grants permission to connect your system to the grid and receive export credits. Your utility issues this approval after reviewing your installation. The process typically ends with a Permission to Operate notification.
In practice, a reputable installer handles both the permitting paperwork and the utility interconnection application as part of the project. Timelines vary by jurisdiction and utility. The key point for a homeowner is simply to recognize that both approvals matter, and that a quote that skips permitting is a warning sign, not a bargain.
A Realistic Look at Payback in 2026
Honest payback math in Arizona for 2026 has to account for the changes above. The loss of the federal residential tax credit removed a large, immediate cost reduction for owned systems. That lengthens the payback period compared with a 2025 installation. At the same time, Arizona’s strong sun and rising electricity rates continue to push the other way.
Several factors shape the picture, and they apply to you rather than universally. Your utility and its export rate determine how much exported energy is worth. Household usage patterns drive the system’s value under net billing. How much solar you can use directly versus export matters most. The state tax credit and tax exemptions reduce costs modestly. Finally, your electricity rate and how fast it rises affect how much each self-consumed kWh saves you.
Because these inputs vary so much, this guide does not put a single payback number on solar in Arizona. Be skeptical of any source that promises one without knowing your details. A careful approach helps. Gather quotes that show the math. Ask installers to base estimates on current export rates. Make sure they assume no federal residential credit for an owned 2026 system. Then have a professional check the assumptions. The honest summary is that solar can still make financial sense for many Arizona homeowners. Strong self-consumption helps the most. The 2026 math differs from the 2025 math and deserves a fresh, individualized look.
The Bottom Line on Arizona Solar Incentives
Arizona solar in 2026 runs on a different set of rules than it did even recently. The federal residential tax credit for owned systems has ended. Arizona now uses net billing rather than traditional net metering. Your specific utility sets the export rate that drives much of the math. The state’s own incentives also remain in place. They include the 25% state tax credit capped at $1,000, the sales tax exemption, and the property tax exemption. These still help.
None of this gives you reason to dismiss solar in Arizona. None of it gives you reason to rush either. It is a reason to base decisions on current information rather than older guidance. Much of that guidance still circulates online and is now wrong. Incentives and rates change and depend heavily on your circumstances. So treat this guide as orientation, not as a final answer. Confirm current terms with your utility. Verify permitting requirements with your local office. Consult a qualified tax professional about how any credit or exemption applies to you. Accurate, current, individualized information is what makes a solar decision a sound one.
Frequently Asked Questions
Does Arizona have net metering in 2026?
Not in the traditional sense for new residential customers. Arizona has moved to net billing. Under net billing, the utility credits the electricity you export at a utility-set rate. That rate falls below the retail rate you pay for electricity. APS phased out traditional net metering years ago, and SRP retired its remaining net metering plans in late 2025. Confirm your specific utility’s current structure directly with them.
Is there still a federal solar tax credit in 2026?
The federal residential solar tax credit for customer-owned systems ended. The One Big Beautiful Bill Act, signed in July 2025, dropped the Section 25D Residential Clean Energy Credit to zero. That applies to owned systems installed after December 31, 2025. Third-party-owned systems, such as leases and power purchase agreements, may still qualify under a separate commercial credit. Confirm your situation with a tax professional.
What solar incentives does Arizona still offer?
Arizona’s state-level incentives remain in place. They include a state income tax credit worth 25% of system cost, capped at $1,000, an exemption of solar equipment from state sales tax, and an exemption of the added solar home value from property tax assessment. These are more modest than the former federal credit but still reduce the cost of going solar. Confirm current details with the Arizona Department of Revenue and a tax professional.
What is the difference between net metering and net billing?
Under traditional net metering, you earn credit for exported solar electricity at the full retail rate. An exported kWh is worth the same as one you buy. Under net billing, which Arizona uses, your utility credits exported electricity at a lower export rate. Consuming your solar power delivers more value than exporting it. This affects how you should size and use a system.
How much is the Arizona state solar tax credit?
Arizona’s residential solar tax credit equals 25% of the cost of the solar energy system, capped at $1,000. You claim it on your Arizona state income tax return. Most systems reach the $1,000 cap. If your state tax liability falls below the credit in the installation year, you can generally carry the unused portion forward. Confirm the current rules with a tax professional.
Why does my Arizona utility matter so much for solar?
Each major Arizona utility, APS, SRP, and TEP, sets its own export rate and rate structure, so the same solar system can have different economics depending on your provider. SRP, for example, is known for rate structures that can include demand and fixed charges. Always confirm your own utility’s current export rate, rate plans, and any extra charges before sizing a system.
Do I need permits to install solar in Arizona?
Yes. A grid-connected solar installation in Arizona generally requires a local building or electrical permit and inspection from your city or county, plus interconnection approval from your utility, which ends with Permission to Operate. A reputable installer handles both as part of the project. A quote that skips permitting should be treated as a warning sign.
Is solar still worth it in Arizona in 2026?
It depends on your specifics. The end of the federal residential credit lengthened payback for owned systems, while Arizona’s strong sun and rising electricity rates push the other way. The value depends on your utility’s export rate, your usage pattern, and how much solar you use directly. Solar can still make sense for many Arizona homeowners, but the 2026 math differs from prior years and deserves an individualized review.
