Is Solar Worth It in Arizona in 2026?

What changed in 2026
The federal residential solar tax credit (§25D) expired December 31, 2025 — eliminated by the One Big Beautiful Bill Act. A system that would have qualified for a $8,100 federal credit in 2025 now only has Arizona's $1,000 state credit. Payback periods are 2–3 years longer than pre-2026 estimates. Every guide quoting the “30% federal tax credit” is now out of date.
The direct answer
Solar is worth it for most Arizona homeowners who check all three boxes: you own your home, your monthly electric bill is above $150, and you have a south- or west-facing roofwith minimal shade. Arizona's 300+ sunny days give you more generation potential than almost anywhere in the country, and electricity rates are rising — meaning every year you wait, the savings comparison gets worse.
The federal tax credit's expiration changed the math, but it didn't break it. A well-designed system still delivers $38,000–$44,000 in lifetime savings for the average Phoenix-area homeowner. The payback period is now 7–10 years instead of 5–7 years — still a strong return on a 25-year asset.
How your utility affects the answer
The single biggest factor in Arizona solar ROI isn't your roof or your system size — it's your utility. APS, SRP, and TEP pay different rates for excess solar you send to the grid, and those rates determine how fast your system pays for itself.
| Utility | Export Rate | Rate Lock | Demand Charges | Payback | Battery |
|---|---|---|---|---|---|
| APS | $0.0617/kWh | 10 years | None | 7–9 years | Optional |
| SRP | $0.0345/kWh | None | ~$32/mo fixed + peak demand | 10–12 years | Strongly recommended |
| TEP | ~$0.057/kWh | 10 years | None | 7–9 years | Optional |
Rates as of June 2026. APS export rate ($0.0617/kWh) is Tranche 2025 (Sept 1, 2025–Aug 31, 2026) and declines ~10%/yr through 2032. Compare APS vs SRP in detail →

When solar is NOT worth it in Arizona
Solar works for most, but not all. Be honest with yourself about these situations:
You rent your home
You don't own the roof, so you can't install panels. Some landlords will consider it, but it's uncommon. Look into community solar programs instead.
Your electric bill is under $100/month
A system sized to offset a small bill may take 15+ years to pay back. The fixed costs of installation and permits are harder to justify at low usage levels.
Your roof needs replacement within 5 years
Removing and reinstalling solar panels costs $1,500–$3,000. Replace the roof first, then go solar — or budget the panel removal into your roof replacement project.
You're planning to sell within 2–3 years
Solar generally adds home value, but markets vary. If you're selling before the system meaningfully reduces your bills, you may not fully capture the investment at sale.
You're being pressured to sign immediately
Legitimate installers don't use artificial urgency. "This price expires tonight" is a red flag. Get at least 3 quotes before signing anything.
