This guide explains solar panel cost Arizona homeowners may see, using the state average installed price of $2.26 per watt (EnergySage Arizona cost data (average, before incentives), October 2026) before incentives. At that price a 7 kW system costs about $15,820. Homeowners who buy a system in 2026 get no federal tax credit, so that price is close to what you actually pay.
Solar panel cost Arizona: compare typical system sizes
Installers price systems by the watt, so the size you need drives the total. At the average price above:
| System size | Estimated installed cost |
|---|---|
| 5 kW | about $11,300 |
| 7 kW | about $15,820 |
| 9 kW | about $20,340 |
| 11 kW | about $24,860 |
EnergySage reports a range of $25,688 to $34,754 for a 13.39 kW system in Arizona, which is about $1.92 to $2.60 per watt. Real quotes vary with your roof, equipment, permitting and the company. Compare quotes in dollars per watt (total price ÷ system watts) so different system sizes line up.
No federal tax credit for buyers in 2026
The 30% federal credit for homeowners (Section 25D) ended for systems placed in service after December 31, 2025 (Solar.com). If you buy with cash or a loan, do not subtract 30% from any quote. Companies that own a system on your roof (a lease) can still claim a business credit; see our lease vs. buy guide.
Arizona’s electricity rate
The average Arizona residential rate was 15.05¢ per kWh (U.S. EIA, Electric Power Monthly (residential average price), updated automatically, August 2026). Each kWh your panels make saves you that much only when it replaces power you would have bought, so payback depends heavily on your own bill. Use the rate printed on your bill in the calculator if you can.
Selling extra power back in Arizona
This guide does not state an Arizona export rate, because we have not confirmed one from a regulator. Ask your electric utility in writing how it credits power you send to the grid, and get the answer before you sign a solar contract.
Arizona property tax treatment
Under Arizona Revised Statutes Section 42-11054, solar energy devices, grid-tied photovoltaic systems and similar systems designed to produce solar energy primarily for on-site use are considered to add no value to the property for property tax valuation. Ask your county assessor how it applies to your home.
We have not verified any statewide Arizona rebate for solar or batteries as of the review date above. Some utilities and cities run their own programs; ask yours.
HOAs and solar in Arizona
Under Arizona Revised Statutes Section 33-1816, an association may not prohibit installing or using a solar energy device. It may adopt reasonable rules about placement if they do not prevent installation, impair how the device works, restrict its use, or adversely affect its cost or efficiency. Submit your plans as your association requires.
Heat, wind, roofs and insurance
- Ask each installer how the panels perform in high heat, what wind rating the racking is installed to, and confirm the job will be permitted and inspected.
- If your roof is near the end of its life, price a re-roof first. Removing and reinstalling panels later adds cost.
- Call your homeowners insurer before you sign to ask how solar affects your coverage and premium.
Questions to ask every installer
- What is the price per watt, and what exactly is included (permits, monitoring, roof work, electrical upgrades)?
- Which panels and inverters, and what are the product and workmanship warranties?
- How did you estimate my production, and how did you account for shade?
- Which utility rules and incentives does your savings estimate assume, and how will my utility credit exported power?
- Which Arizona and local licenses and permits apply, and who does the installation: your crew or a subcontractor?
