More than almost anything else. Arizona has three major utilities and they treat solar very differently:

• APS — credits exported solar at roughly 7.6–10¢/kWh, no demand charges
• SRP — credits at roughly 3¢/kWh and bills demand charges based on your single highest peak hour
• TEP (Tucson area) — credits below retail, similar structure to APS

In the Phoenix metro, the APS/SRP boundary runs by neighborhood, not city line. Check your electric bill before you assume — it changes the math more than your roof does.

Is solar panel installation in Arizona eligible for any incentives and tax credits?

Yes, though the 30% federal residential credit (Section 25D) expired December 31, 2025 — cash and loan purchases in 2026 receive no federal credit.

What Arizona homeowners can still use:

• Arizona Residential Solar Tax Credit — 25% of system cost, capped at $1,000, against your state personal income tax
• Sales tax exemption on solar equipment
• Property tax exemption — your assessment doesn’t rise from the value solar adds
• Net billing — credit for excess power sent to the grid (worth more on APS than SRP)
• APS Virtual Power Plant — roughly $150–$500/year with a battery, APS customers only
• Lease/PPA financing — the 30% credit still exists under Section 48E for third-party owned systems, where the owner claims it and passes the value through as a lower payment. This is currently the only route to federal credit value on a residential system.

General information, not tax advice — confirm your situation with a tax professional.

No. If your system was installed and operational before December 31, 2025, you claim the credit on the return for the year it was placed in service. That isn’t retroactively removed — the expiration only affects systems installed in 2026 and after.

It depends on your actual electricity usage, roof space, and shading — not home size. Arizona homes are cooling-dominant, so your summer peak drives the sizing, not your annual average. We’ll pull your 12-month usage and design to your real load. Get a free estimate to see your number.

Depends on your utility. On SRP, usually yes — demand charges and a 3¢ export rate mean storing your production is worth substantially more than exporting it. On APS, a battery improves returns and unlocks the VPP program, but solar-only still works. On TEP, it’s worth running the numbers.

There’s also outage protection: solar alone won’t power your home when the grid goes down. Only a battery will.

Homes with owned solar systems generally sell for more than comparable homes without them. Arizona’s property tax exemption means that added value doesn’t raise your assessment. The effect depends on your market, system age, and whether the system is owned or leased — owned systems carry more value at resale.
