Dean has connected tens of thousands of homeowners with residential solar installers across all 50 states since 2021, and works directly with installers on pricing and financing.
Arizona has the sun, the cheap installation, and the huge cooling loads, and still manages to produce disappointed solar owners every year, because worth-it here is an alignment question between when your system produces, when your household consumes, and how your specific rate plan prices the difference. APS, SRP, and TEP run three different regimes, exports earn below retail, and the same array that thrives under one plan underperforms under another. APS credits exports at 6.171¢ per kWh on the tranche running through August 31, 2026, with a step-down expected September 1; TEP pays 5.13¢ as of October 1, 2025; SRP pays 3.45¢ as of November 2025. APS and TEP lock the rate for 10 years from interconnection, and some SRP plans end in November 2029, so confirm the end date. Retail net metering closed to new customers in 2017 and 2018. The statewide average retail rate is 15.72¢ per kWh, which is statewide context; your plan sets what self-consumed power actually avoids.
The panels do not decide the Arizona verdict. The plan does, and most bad outcomes were mispriced on day one.

The Alignment Matrix
Your situation | Without storage | With storage |
|---|---|---|
Daytime-heavy usage, any utility | Usually worth it: self-consumption captures retail value directly | Stronger still, plus outage cover |
Evening-heavy usage on APS or TEP time-of-use | Marginal: exports at low credit, purchases at peak prices | Often worth it: the battery moves noon production into expensive evenings |
SRP demand-based plan | Frequently disappointing: solar alone does not control the demand peak | Conditional yes: storage plus controls addresses the peak the plan actually bills |
Small bill, mild usage | Rarely worth the roof work | Rarely pencils on savings alone |
A battery raises self-consumption but adds cost the export gap then has to justify; price the system with and without storage and compare the two paybacks directly before treating any “with storage” cell as yours.
The verdict changes with the state line; see the worth-it verdicts for all 50 states for how.
The regimes themselves are mapped in Arizona solar incentives, and the entry price, among the country’s lowest, in what solar costs in Arizona.
Why Cheap Entry Does Not Settle It
Arizona’s low installed prices shorten payback when the value side cooperates, and change nothing when it does not. The typical 7.21 kW Arizona system, about $17,200 before incentives, costs less here than almost anywhere, but production exported at 3.45¢ to 6.171¢ pays back slowly at any sticker. The worth-it work is therefore modeling: your plan named, the export credit stated separately, your self-consumption derived from real usage, heat derate included, and the battery given its own line and its own arithmetic.
Share of output used as it is made | Value in year one | Simple payback |
|---|---|---|
30%, a house empty on weekdays | $1,165 | 15 years |
50%, mixed occupancy | $1,412 | 12 years |
70%, home through the day with daytime cooling | $1,658 | 10 years |
The federal residential credit is $0 for systems whose installation is completed after December 31, 2025, which removes the cushion that used to forgive sloppy modeling. A third-party owner may qualify for the separate Section 48E business credit under current deadlines, but power purchase agreements are restricted in Arizona, so that route is narrow here, and whether any of that value reaches a lease payment depends on the contract. Our Arizona installer rankings are ordered on exactly this fluency.
When Arizona Solar Is Not Worth It
- A proposal with one blended rate. Under Arizona’s structures that is not a model; the verdict built on it is noise.
- SRP demand plans with no demand strategy. The most repeatable disappointment in the state.
- Evening-heavy homes refusing storage. The rules price that configuration against you three times a day.
- An aging roof, especially tile. Removal and reset is skilled money; sequence the roof first.
- A $0-down pitch carrying the math. Its plan problem is worse; see what free solar really means in Arizona.

Frequently Asked Questions
Yes, solar panels are worth it in Arizona for daytime-heavy households, and for most others when paired with storage: cheap installation plus large cooling loads carry it. The failures cluster where production and consumption misalign under time-of-use or demand-based plans.
Arizona compensates exports below retail, and solar still clears for aligned households. Self-consumed power avoids full retail regardless, which is why usage timing and storage decide the modern Arizona verdict.
Not for daytime-heavy homes; frequently decisive for everyone else. Time-of-use windows and SRP’s demand components are precisely what storage monetizes, and it should be judged as its own line item.
Almost always plan misalignment: systems modeled on blended rates, demand charges never mentioned, or export credits assumed at retail.
It trims summer output through heat derate, which a complete proposal includes, and it also drives the cooling loads that make solar valuable here. Net effect: still worth it when modeled truthfully.
On the typical 7.21 kW Arizona system, about $17,200 before incentives and producing roughly 12,900 kWh a year, simple payback runs about 10 years at 70% self-consumption, about 12 years at 50%, and about 15 years at 30%, with exports credited at 6.171¢ in APS territory and self-used power valued at the 15.72¢ statewide average. That average is context, not an APS bill rate, so pull your own plan’s per-kWh rate and rerun it. The $1,000 state credit trims under a year off each. Plan to stay past the payback year, or to sell to a buyer who values the locked export rate.
Methodology: payback and savings modeled at $2.39 per watt as of March 1, 2026, with no federal residential credit for host-owned systems, exports at each utility’s published credit, rate escalation at the state five-year average of 3.71%, 0.5% annual panel degradation, and a 25-year horizon.
