Solar Panel Cost in Arizona (2026): Prices, Export Rates and Payback

Updated Data verified Nov 5, 2026

Arizona has some of the best sunshine in the country: a south-facing array in Phoenix produces about 1,755 kWh per kW per year[1]. At Berkeley Lab's Arizona median of $3.10 per watt est.[2], a system that covers an average home's 1,075 kWh a month[3] is about 7.4 kW est.[1,3] and costs roughly $19,500 to $26,500 est.[1,2,3] before incentives. What decides your payback is less the sun than your utility: APS, TEP and SRP pay very different amounts for the power you send back to the grid.

Estimates use the inputs above and the assumptions in our methodology: APS credits exports at 5.55¢ per kWh (Rate Rider RCP (Resource Comparison Proxy export rate)). Solar customers also pay $0.24 per kW of panels a month, included in the estimates. Prices rise 2.5% a year; panels lose 0.5% a year.

What changed for Arizona buyers in 2026

The biggest change is federal. The Federal Residential Clean Energy Credit (25D)[4] no longer applies to systems whose installation is completed after December 31, 2025, so a 2026 cash purchase gets no federal credit. Arizona's own Arizona Residential Solar Energy Devices Tax Credit (A.R.S. 43-1083)[5] still applies: 25% of the cost of the device, up to $1,000 (lifetime cap per residence); unused credit carries forward up to 5 years[5]. It is small next to the old federal credit, which is why the gap between your retail price and your utility's export rate now matters more than ever.

The second change is the export rate. APS customers who apply in the current tranche lock in 5.55¢ per kWh[6], and TEP customers lock in 4.62¢ per kWh[7]. Both rates are set under the Resource Comparison Proxy and step down each year, so the application date matters.

Why your utility matters more than your roof

Arizona ended retail net metering for new APS and TEP customers in 2017 (ACC Decision 75859). Today:

  • APS credits exports at the RCP rate above, locked for 10 years[6] from your application. Solar customers must choose a time-of-use plan, and APS adds a grid access charge per kW of panels: $0.242 per kW-dc of solar nameplate capacity added to the monthly bill on TOU-E ($0.215/kW-dc on R-3).[8]
  • TEP works the same way with its own RCP rate, and requires a time-of-use plan for solar customers: Customers on the RCP export rider must be on a residential time-of-use rate.[9]
  • SRP, which serves much of the Phoenix metro and is not regulated by the Arizona Corporation Commission, now pays 1.87¢ per kWh[10] on its newer plans. That is far below what you pay for power, so SRP customers save mostly on the energy they use as it is produced.

Because exports are worth a fraction of retail everywhere in Arizona, size your system to what you use during the day and early evening rather than to your total yearly use, and look hard at shifting pool pumps, pre-cooling and EV charging into sunny hours. A battery can make sense for SRP and APS customers on demand-charge plans, but price it against the export gap, not against a generic promise of independence.

How Arizona prices compare

Berkeley Lab's latest data put Arizona's median installed price at $3.10 per watt est.[2], below the U.S. median of $3.60 per watt est.[2]. Cash buyers nationally paid a median of $3.00 per watt est.[2] while loan-financed systems came in at $4.50 per watt est.[2], which mostly reflects financing fees built into the price. If you finance, ask every installer for the cash price of the same system in writing.

Arizona rules that protect you

Arizona law gives solar buyers specific protections. Solar sale or lease agreements must let the buyer or lessee cancel for at least three business days after signing and before installation, and must include bold disclosures that utility rates and tax incentives can change.[13] Leases cannot start charging early either: Recurring solar lease payments cannot start until the utility grants permission to operate and the system is energized and interconnected.[13] HOAs cannot ban solar: Planned-community associations cannot prohibit installing or using a solar energy device; they may adopt reasonable placement rules only if those rules don't prevent installation, impair function, or adversely affect cost or efficiency. Courts award attorney fees to a party that substantially prevails against the board.[14] Our Arizona installer guide shows how to check a contractor's license with the Registrar of Contractors before you sign.

Incentives that lower the price in Arizona

Business credit for leased and PPA systems (48E)

Claimed by the system owner, not the homeowner; solar must begin construction by July 4, 2026 or be in service by December 31, 2027[16]

If a company owns the panels on your roof (a lease or power purchase agreement), that company may claim the business clean electricity investment credit and can reflect it in your price. You cannot claim it yourself.

Who
Third-party-owned systems (leases and PPAs). Ask the provider whether the price assumes this credit.

Arizona TPT (sales tax) deduction and use-tax exemption for solar energy devices

Sales of solar energy devices by a registered solar energy retailer are deducted from the state transaction privilege tax base; purchases from a registered solar retailer or contractor are exempt from use tax[11]

Use tax: A.R.S. 42-5159(E) (https://www.azleg.gov/ars/42/05159.htm): tax 'does not apply to the purchase of solar energy devices from a retailer that is registered with the department as a solar energy retailer or a solar energy contractor.' The separate prime-contracting deduction for solar installation contracts (A.R.S. 42-5075(B)(13)) applied only to taxable periods ending before January 1, 2017, so how a turnkey installation contract is taxed today was not verified.

Applies to solar energy devices sold by a retailer registered with the Arizona Department of Revenue as a solar energy retailer. Buyers should confirm their seller/installer is registered.

Arizona property tax exclusion for residential solar (A.R.S. 42-11054)

Solar energy devices and grid-tied PV systems primarily for on-site use are considered to add no value to the property for property tax assessment[12]

Subsection C(2). percent=100 means 100% of the system's added value is excluded from assessed value. For personal-property solar (C(3)), A.R.S. 42-13056 values it at depreciated original cost with assessor percentages of 3% in years 1-3 rising to 100% in year 10 (https://www.azleg.gov/ars/42/13056.htm).

Who
Owner-installed solar energy devices and grid-tied PV systems designed primarily for on-site consumption. Systems characterized as personal property (e.g., third-party-owned) are valued under A.R.S. 42-13056 instead.

How Arizona utilities credit your solar

Retail net metering ended for new APS and TEP customers in 2017. Both now credit exports at the Resource Comparison Proxy (RCP) rate, which falls by up to 10% a year and is locked for 10 years from your application. SRP, which serves much of the Phoenix area, sets its own export rates and is not regulated by the Arizona Corporation Commission.[14]

FAQ

Frequently asked questions

How much does a solar system cost in Arizona?

About $22,900 est.[1,2,3] before incentives for a 7.4 kW est.[1,3] system that covers average use, at the state median of $3.10 per watt est.[2]. The Arizona Residential Solar Energy Devices Tax Credit (A.R.S. 43-1083)[5] then takes off up to $1,000[5].

Is solar still worth it in Arizona without the federal tax credit?

It can be, but the margin is thinner. With an average price of 15.36¢ per kWh[15] and the APS export rate, our model estimates about 15 years est.[1,2,3,6,15] for a cash purchase. Using more of your solar at home, rather than exporting it, is the main lever you control.

What does APS pay for solar exports?

New APS customers in the current tranche lock in 5.55¢ per kWh[6] for 10 years[6]. That is roughly a third of what you pay per kWh, so exported energy is worth far less than energy you use yourself.

Should SRP customers get a battery?

Possibly. SRP's newer plans pay 1.87¢ per kWh[10] for exports, so storing midday solar for the evening peak is worth more than exporting it. Compare the battery's price with the yearly value of the energy it would shift, using your own usage pattern.
