Arizona Solar Incentives — 2026
| Incentive | Value |
|---|---|
| Federal Residential ITC (Section 25D) | Expired 12/31/2025 |
| Systems installed before 1/1/2026 | 30% ITC still claimable |
| Arizona state/utility incentives | Federal 30% ITC + Net Metering (varies by utility) + APS/SRP rebates (limited) + 25% state tax credit (capped at $1,000) |
| Est. payback period (Arizona) | ~6–9 years |
Federal residential ITC expired Dec 31, 2025 (One Big Beautiful Bill). Solar leases/PPAs: commercial credit continues through 2027. State incentives subject to change — consult a tax professional.
Solar System Size vs. Estimated Savings — Arizona
Based on ~5.5 peak sun hours/day and estimated $11¢/kWh electricity rate in Arizona.

Going Solar in Arizona — Key Insights
1. Arizona Solar Market Overview
Arizona ranks among the top states for solar production per watt installed — with 300+ sunny days and intense solar irradiance, systems produce 20–30% more than in northern states. This offsets Arizona's relatively high solar installation costs and makes payback periods among the shortest nationally. APS and SRP offer different export credit structures.
2. Top Tip for Arizona Solar Buyers
Arizona's extreme heat (110°F+) slightly reduces panel efficiency but more than compensated by sun hours. Orient panels south or slightly west to capture afternoon peak production (aligns with APS's time-of-use peak hours). Consider a modest battery for off-peak shifting — APS TOU rates make this financially attractive.
3. System Size Guide for Arizona
Average Arizona home uses ~1,000–1,200 kWh/month (higher in hot climates with AC). A 6–8 kW system typically covers most usage. Always get a system sized to 90–110% of your actual annual consumption — oversizing costs more without proportional benefit under most net metering policies.
FAQs — Solar Panels in Arizona
Solar panels in Arizona cost $21,340 on average for a 7 kW system before incentives. After the 30% federal ITC and Arizona's $1,000 state credit, net cost is roughly $13,938. Arizona's exceptional sun resources give some of the shortest payback periods in the US: 6–9 years. Production often exceeds nameplate capacity vs northern states.
Solar is financially positive for most Arizona homeowners, though the calculus changed in 2026 after the federal residential ITC expired on December 31, 2025. Arizona's incentives: Federal 30% ITC + Net Metering (varies by utility) + APS/SRP rebates (limited) + 25% state tax credit (capped at $1,000). Estimated payback without federal ITC: 6–9 years. With a 25-year panel lifespan and rising electricity rates, solar still provides positive lifetime returns in most states.
Most Arizona homes need a 5–10 kW system. A 7 kW system produces approximately 14,053 kWh/year in Arizona. Divide your annual kWh usage by that figure to estimate the right size. Your installer will perform a site assessment to optimize for your specific roof and usage patterns.
Solar financing options in Arizona in 2026: (1) Cash purchase — best long-term ROI; no federal ITC (expired 12/31/2025) but state incentives apply; typically $100–$250/month in energy savings. (2) Solar loan — own the system; pay from energy savings; rates 5–10% APR via GreenSky, Mosaic, or your installer. (3) Solar lease/PPA — $0 down; the solar company may still qualify for a commercial tax credit through 2027 and passes savings to you via rates below your utility bill — more competitive now that the homeowner cash ITC is gone. (4) HELOC — often lowest interest rate (6–8% APR). Avoid loans with "dealer fees" above 2% — these inflate the effective loan amount.
The ITC expiry changed the comparison. Previously, buying solar gave you a $6,402 federal credit (30% of cost) that leasing didn't — making buying clearly superior. In 2026, that credit is gone for new purchases, but solar companies (lease/PPA providers) can still claim a commercial credit through 2027 and may pass savings to you via lower lease rates. If your state has strong incentives (Arizona's state credit further benefits purchase), buying/financing still typically produces better 25-year returns. Leasing makes sense for zero upfront cost with still-lower-than-utility rates.
