What changed for Arizona solar costs in 2026
The federal 30% solar tax credit expired December 31, 2025 — raising the effective net cost for 2026 buyers compared to prior years. Arizona's own incentives (25% state tax credit, sales tax exemption, property tax exemption) are unchanged and remain the primary tools for reducing upfront cost. Utility rate increases from APS and TEP strengthen the long-term ROI even as the federal credit is gone.
What's Included in an Arizona Solar Installation Quote
When you get a quote from an Arizona solar company, the price per watt covers everything from hardware to activation — not just the panels.
| Component | % of Total Cost |
|---|---|
| Solar panels | ~55–60% |
| Inverter(s) | ~10–15% |
| Labor & installation | ~15–20% |
| Permits & inspections | ~5–8% |
| Racking & wiring | ~5–8% |
Ask every installer: break out the price per watt for hardware separately from labor and soft costs. This is the most reliable way to compare quotes apples-to-apples across multiple companies.
Solar Cost by City in Arizona (2026)
Installation costs vary by city based on local installer density, roof types, and permitting complexity. All figures are before Arizona incentives — subtract ~$2,400 in typical upfront savings from the sales tax exemption and state tax credit.

How Your Utility Affects Payback — Not Just Price
The sticker price of a solar system is only half the equation. Your utility's export rate determines how fast you recover that cost — and the difference between APS, SRP, and TEP is significant.
APS (Arizona Public Service)
Best export rate among major AZ utilities, locked 10 years from interconnection. Most Phoenix metro homeowners.

Competitive export rate plus Energy Storage Rewards (~$720/yr for qualifying battery systems). Tucson metro homeowners.
Full TEP guide →arrow_forwardSRP (Salt River Project)
Lowest export rate in Arizona — net metering retired Nov 2025. Battery storage significantly improves ROI for SRP customers.

Two homes on the same street can get quotes $5,000 apart. Here's what explains the difference.
System size
The single biggest cost driver. A 14 kW system costs $8,000–$10,000 more than a 10 kW system at the same cost per watt. Right-sizing to your actual usage — not your maximum roof capacity — is especially important on SRP where oversizing earns almost nothing.
Roof type and condition
Tile roofs (the most common in Arizona) cost $400–$800 more to install on than composition shingle. Older roofs approaching replacement age may require a separate reroofing cost — a good installer will flag this before you sign.
Panel and inverter brand
Premium panels (REC Alpha, SunPower Maxeon) add $1,500–$3,000 over mid-range options (Q CELLS, Silfab) for comparable system size. In Arizona's high-UV environment, degradation rates and temperature coefficients matter more than in cooler climates.
Installer margin
Labor and overhead vary 15–25% between companies. The only way to find the competitive rate in your market is to get three quotes from NABCEP-certified installers. Price per watt — not total price — is the right comparison metric.
Arizona Incentives That Reduce Your Net Cost
Three state-level incentives apply to every Arizona residential solar installation in 2026 — regardless of your utility.
Arizona Residential Solar Tax Credit
Up to $1,00025% of your installation cost, credited against your Arizona state income tax. Unused credit rolls over for up to 5 additional tax years. Applies to primary and secondary residences.
Arizona Sales Tax Exemption
~$1,300–$1,600Arizona's 5.6% Transaction Privilege Tax does not apply to residential solar panels, inverters, batteries, racking, or installation labor. On a $25,000 system, this saves approximately $1,400 upfront.
Arizona Property Tax Exemption
Ongoing savingsSolar-added home value is excluded from your property's assessed value under A.R.S. §42-11054. If solar adds $15,000–$20,000 to your home's market value, none of that increase is taxed.
Note: The federal 30% solar Investment Tax Credit expired December 31, 2025. Any installer still quoting this credit for 2026 installations is working from outdated information. See the full Arizona incentives guide →
