What Arizona still offers after the federal credit ended
Every incentive on this page is verified against Arizona government sources - and the expired ones salespeople still quote are called out.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Nogales systems completed in 2026 get $0 from it.
Under Arizona's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Nogales homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
If a salesperson in Nogales tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Arizona's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.
Leased and PPA systems deserve extra scrutiny in 2026: the sales pitch often bundles 'tax savings' that now accrue to the leasing company under separate commercial rules - not to you. Get every claimed saving in writing, attributed to a specific law, before signing a 20-25 year contract.

Arizona rules that decide your payback
| Rule | Arizona status |
|---|---|
| Export compensation (net metering) | Traditional retail net metering is CLOSED to new customers; exported energy is bought back under an avoided-cost export rate (Resource Comparison Proxy, RCP), set annually by the Arizona Corporation Commission, well below the retail rate. The rate in effect when a customer requests interconnection is locked in for 10 years, and the RCP may not fall more than 10% per year. Customers interconnected before the 2018 cutover were grandfathered on net metering for 20 years. |
| State incentive | Credit for Solar Energy Devices (Arizona Form 310, A.R.S. 43-1083) - a nonrefundable state income tax credit equal to 25% of the device cost, capped at $1,000, with unused amounts carried forward up to five consecutive tax years. |
| Sales tax on the system | Exempt |
| Property tax on added home value | Excluded |
A.R.S. 33-1816 says an HOA "shall not prohibit the installation or use of a solar energy device" and may only adopt placement rules that do not impair the device's function, cost or efficiency, with attorney's fees awarded to a homeowner who prevails; separately, Arizona's $156 million "Solar for All Arizonans" low-income rooftop solar program is suspended - the Governor's Office of Resiliency received an EPA grant termination notice on August 7, 2025 and states the program "is unavailable until further notice."

What this means for Nogales roofs
The honest 2026 answer for Nogales: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is Arizona's export compensation, covered in the net metering section.

Getting Nogales quotes
Marketplace platforms collect bids from multiple AZ installers against the same spec, which is the only clean way to compare - same roof, same size, different prices. Getting quotes is free and does not commit you to anything; prices come from the installers, never from this site.

Common questions
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
Is there still a federal solar tax credit in 2026?
No. The 30% Residential Clean Energy Credit was repealed effective for systems placed in service after December 31, 2025, per the IRS. Only systems finished by the end of 2025 qualified. State-level incentives are separate and some survive - check the state page in this guide.
Is solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
