Not in Arizona?

Arizona kept what almost every other state lost: a 25% state income tax credit, up to $1,000, still alive after the federal credit died. What it never kept is generous export pay: APS, SRP and TEP credit your surplus at a fraction of retail, and SRP adds demand-based rate plans on top. EcoGen America shows you the desert math straight.

About EcoGen America

Arizona Has the Sun. The Tariffs Have the Fine Print.

Arizona is the country’s best solar resource attached to some of its stingiest export tariffs. There is no retail net metering here: APS credits surplus under its Excess Energy Credit at roughly 3¢, SRP pays roughly 4 to 6¢ and pairs solar with demand-based rate plans, and TEP sits near 6¢, all against retail power at 13 to 15¢.

What Arizona kept is rarer: a 25% state income tax credit up to $1,000, still claimable in 2026 after the federal residential credit expired, plus a 5.6% transaction-privilege-tax waiver and a property-tax exemption on the added value.

The design consequence is the same one the tariffs imply: size to what you use while the sun is up, and treat exports as spare change. Heat is the second Arizona variable; panels derate in June rooftop temperatures, and tile roofs demand installers who actually know them.

EcoGen America models your utility’s actual export rate and rate plan, checks quotes against real Arizona pricing, and matches you with installers who have desert scars, not just desert listings.

APS, SRP, TEP: What Your Exports Actually Earn

Arizona ended retail net metering years ago. What replaced it differs by utility, and the difference decides your system design.

Utility
Export Credit (Approx.)
The Catch
APS
~3¢/kWh Excess Energy Credit
Rate has stepped down over time; locked per interconnection vintage
SRP
~4-6¢/kWh
Solar customers land on demand-based plans; a hot-afternoon spike can cost more than the exports earn
TEP
~6¢/kWh
Vintage-locked export rate; confirm the current schedule before modeling
Approximate 2026 export crediting versus retail rates of 13-15¢; exact values vary by plan and interconnection date. Confirm your utility”s current schedule in writing before trusting any projection.

The through-line: every Arizona utility pays a fraction of retail for exports, so the winning design maximizes what you consume as you produce, and on SRP it manages demand peaks as carefully as it harvests sun.

Sun, Tariff, Credit: Buying Solar the Arizona Way

1

Map

Identify your utility and its current export rate and rate plan. APS, SRP and TEP run three different deals, and SRP's demand plans change the design entirely.

2

Size

Design to daytime self-consumption, with pre-cooling and load-shifting doing real work in an Arizona summer. Exports earn a fraction of retail.

3

Claim

File Arizona Form 310 for the 25% state credit, up to $1,000. It is the last meaningful solar tax credit standing in most of the country.

Arizona Contract Checks

Arizona Contracts: The Four Lines That Matter

Before analyzing system performance, ensure these four contractual protections are clearly written. These standards apply to any quote in any state.

Clause to verify: Does the contract separate the system cost from financing fees? Always request the Cash Price in writing for comparison.
Clause to verify: “Is there a ‘Performance Guarantee’ section that details cash reimbursement if the system generates less than promised?”
Clause to verify: “Locate the ‘Workmanship Warranty’. It must explicitly cover roof penetrations and leaks for at least 10 years.”
Clause to verify: “Check the ‘Transferability’ section. Are there excessive fees ($500+) or conditions that make selling your home difficult?”
Verify your paperwork

Use these checks to validate any quote you receive. If the contract fails these basics, don't sign.

Arizona's Fine Print, Card by Card

Net Billing Rule

You sell excess power for cheap (~6–7¢) but buy it back at ~12–15¢.

Estimate export impact

Heat Degradation

Cheap inverters fail in 110°F+ heat. Efficiency drops as temps rise.

Check production factors

Tile Roof Risks

Drilling without proper flashing causes leaks. Workmanship warranty is key.

Dealer Fees

Low interest loans often hide 25-30% markup fees added to the principal.

Where Arizona Solar Overpromises

The best sun in America attracts the boldest sales math in America. Here is who should slow down.

  • Anyone whose projection assumes retail-rate exports. No Arizona utility pays that. A model crediting exports above roughly 6¢ is fiction with a tan.
  • SRP customers who skipped the demand-plan math. A single hot-afternoon demand spike can erase a month of export credits. If the quote does not model your demand profile, it is not an SRP quote.
  • Empty-by-day households without load shifting. Exports at 3 to 6¢ cannot carry a payback. Pre-cooling and midday appliance timing genuinely change the answer here; no plan for them, no purchase.
  • Tile roofs quoted by shingle crews. Cracked tiles and bad flashing are the classic Arizona complaint. Ask for tile-specific references, not general ones.
  • Heat-blind production estimates. Panels derate on 160° rooftops. An estimate built on lab-condition output overshoots an Arizona June by a wide margin.

What still works for almost everyone: the state credit. 25% of system cost up to $1,000, claimed on Form 310, on top of the sales-tax waiver and property-tax exemption. Small, durable, and real, which is more than can be said for most solar pitches in Phoenix. Run your scenario in our Arizona worth-it breakdown.

Arizona Solar FAQs

Is the Arizona solar tax credit still available in 2026?

Yes. The 25% state income tax credit, capped at $1,000 and claimed on Form 310, survived the federal credit’s expiration, making Arizona one of the last states with a meaningful solar tax credit.

Stack it with the 5.6% transaction-privilege-tax waiver and the property-tax exemption on added value.

Does Arizona have net metering?

Not at retail rates. APS credits exports at roughly 3¢ under its Excess Energy Credit, SRP pays roughly 4 to 6¢ with demand-based plans attached, and TEP sits near 6¢, against retail power at 13 to 15¢.

Your export rate generally locks to your interconnection vintage; confirm the current schedule before signing.

What is the catch with SRP and solar?

Demand charges. SRP’s solar rate plans bill your single highest usage spike each month, so a 5pm July air-conditioning surge can cost more than your exports earned all week.

SRP systems need demand-aware design: load shifting, possibly a small battery, and honest modeling of your usage profile.

Does the heat really reduce panel output?

Meaningfully, yes. Panels lose efficiency as temperature rises, and Arizona rooftops run far hotter than test conditions. Good installers model the derate; optimistic ones quote lab numbers.

Ask what temperature coefficient and rooftop assumptions the production estimate uses.

Who should actually buy solar in Arizona?

Households that consume in daylight or can shift there: home offices, midday EV charging, pool pumps, and anyone willing to pre-cool. For that profile, cheap installs, the state credit and relentless sun still pencil out well.

Export-heavy households on any Arizona utility should size smaller or wait.
