Solar Energy in Mesa, Arizona: What Homeowners Need to Know

A sleek light rail glides through the sunny streets of Mesa, AZ, with vibrant decals promoting exploration.

Mesa is one of the largest cities in the United States — and one of the most solar-dense. Thousands of Mesa homeowners have installed solar over the past decade, attracted by strong sun, high summer electric bills, and aggressive installer sales campaigns across the East Valley.

That growth has produced a lot of successful solar installations. It's also produced a significant number of poorly designed systems, improperly permitted jobs, and homeowners left stranded when their installer closed. AZ Solar Rescue is based in Mesa — this is our home territory, and we know its solar landscape well.

Mesa's Unique Utility Situation

Mesa is one of the few Arizona cities with three different electric utilities serving different parts of town — and which utility you have dramatically affects how solar works for your home.

City of Mesa Electric (Municipal Utility)

A significant portion of Mesa is served by the City of Mesa's own electric utility — one of the largest municipal utilities in Arizona. Mesa's utility has its own solar program, rate structure, and interconnection requirements that differ from APS and SRP. If you're on the City of Mesa electric system, review their solar program before comparing installer quotes.

Salt River Project (SRP)

Parts of Mesa, particularly toward the eastern and southern areas, are served by SRP. SRP retired its traditional net metering program in November 2025 and now uses net billing — meaning excess solar energy exported to the grid is credited at a rate below the retail rate you pay when drawing power back. SRP has time-of-use pricing with peak rates in the late afternoon and evening.

Arizona Public Service (APS)

Some Mesa addresses, particularly toward the northwest areas bordering Tempe and Scottsdale, are served by APS. Like SRP, APS uses net billing and time-of-use pricing.

Mesa homeowners: Before you compare solar quotes, confirm which utility serves your address. The same system size can produce very different financial results depending on whether you're on Mesa City, SRP, or APS — and many installers don't explain this difference clearly.

Mesa Solar Permitting

Mesa processes solar permits through its solar program. The permitting process is well-established given the volume of solar installations in the city. Licensed contractors typically handle the permit application, inspection scheduling, and utility interconnection paperwork.

If your installer pulled permits properly, you should have a permit number on file. If you're not sure whether your system was permitted — especially if you've had issues with your original installer — this is worth verifying. Unpermitted solar work can create problems when you sell your home.

Warning: If a solar company offers to skip the permit to save time or money, walk away. Permitted work protects you legally, ensures code compliance, and is required for your equipment warranty to be honored in most cases.

HOA Rights for Mesa Solar Homeowners

Mesa has hundreds of HOA-governed communities, particularly in the newer subdivisions in the southeast and the established communities near downtown. Arizona law protects your right to install solar regardless of HOA rules.

Under Arizona Revised Statute 33-1816, HOAs in Mesa cannot:

•       Prohibit solar panel installations

•       Impose restrictions that increase your system cost by more than $1,000

•       Require panel placement that reduces efficiency by more than 10%

•       Issue fines or violations that effectively block a legal solar installation

Any HOA restriction that violates this statute is void and unenforceable. That said, following your HOA's submittal process — even when their rules can't legally stop you — tends to make the project go more smoothly.

Solar Incentives Available to Mesa Homeowners in 2026

The federal solar tax credit expired at the end of 2025. Here's what's available now:

INCENTIVE	AMOUNT	STATUS 2026
Federal Residential ITC (25D)	30% of system cost	Expired
AZ State Tax Credit	25% up to $1,000	Active 2026
AZ Sales Tax Exemption	100% of sales tax on equipment	Active 2026
AZ Property Tax Exemption	Added home value excluded	Active 2026
APS Battery Pilot Program	Up to $3,750 (limited enrollment)	Active — APS customers only
SRP Storage Incentives	Varies — check with SRP	Active — SRP customers only
Mesa City Electric Incentives	Check with Mesa Utility directly	Verify current status

Mesa City Electric customers should contact the utility directly about any solar-specific incentive programs. Municipal utilities sometimes offer programs not available through APS or SRP.

The Arizona state tax credit — 25% of system cost up to $1,000 — has no expiration date and is available to all Mesa homeowners regardless of which utility serves their address. File Arizona Form 310 to claim it. Unused credit can be carried forward for up to five years.

Already Have Solar in Mesa? Here's What You Should Know

AZ Solar Rescue was founded in Mesa because this is where the need is greatest. We've worked alongside solar companies serving this area for years — and we've seen what happens when those companies close.

The Roof Replacement Problem

One of the most common issues we see in Mesa: homeowners who replaced their roof and had their solar system removed and reinstalled — incorrectly. This is a specialty that many roofing companies and general solar installers don't do well. If your system was reinstalled after a roof job and hasn't been right since, it's worth having a licensed technician take a look.

Mesa's Aging Installations

Many Mesa solar installations are now 8–12 years old — old enough that inverters are reaching the end of their typical lifespan. A string inverter typically lasts 10–15 years. If your system is approaching that age and production has dropped, a diagnostic visit can determine whether a warranty claim is applicable.

Your Warranty Survived Your Installer

Equipment warranties from SolarEdge, Enphase, Fronius, Tesla, Generac, and other major brands remain valid even when the installing company closes. We file warranty claims on behalf of Mesa homeowners regularly. In most cases, parts are covered — you pay labor only.

The Bottom Line for Mesa Solar Homeowners

Mesa's three-utility situation makes it one of the most important cities in Arizona to get solar planning right. The system design and financial projections that work for a City of Mesa Electric customer can look very different from what makes sense for an SRP or APS customer in a neighboring subdivision.

The good news is that Mesa's solar market is mature, its permitting process is established, and experienced licensed contractors are available. The key is finding one who will design around your specific address, utility, and usage — not just push a standard package.

We're happy to start with an honest conversation about what solar looks like for your home — no sales pressure, just real information.
