Home Solar Cost Guide

Is there still a solar tax credit for San Luis homeowners in 2026?

The 30% federal credit is gone for 2026 installations. What survives for San Luis: Arizona's own incentives and tax treatment - verified against state sources.

The 30% federal solar tax credit ended for installations finished after December 31, 2025 - San Luis systems completed in 2026 get $0 from it.

Installed home solar for San Luis homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.

San Luis, Arizona has about 40,064 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.

If a salesperson in San Luis 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.

The 30% federal tax credit is gone for 2026 installations

The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts the installation completion date, not the contract date.

Arizona rules that decide your payback

RuleArizona 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 incentiveCredit 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 systemExempt
Property tax on added home valueExcluded

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 San Luis roofs

The honest 2026 answer for San Luis: 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.

Same-day contracts are a red flag in this industry. Legitimate AZ installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.

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.

Does solar raise my property taxes?

It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.

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.

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.

How long do solar panels actually last?

Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
