Top picks

Mesa gets over 300 days of aggressive sun every year, making rooftop solar an obvious upgrade. But the local grid changes the math. Much of the city runs on Salt River Project power, and SRP rate plans lean heavily on demand charges. That means throwing panels on the roof without a battery backup might not drop the summer utility bill the way a homeowner expects.
The housing stock here also complicates installations. Contractors working in older central Mesa neighborhoods frequently run into outdated electrical panels that need upgrading before they can handle backfed power. Further east, developments are filled with fragile clay and concrete tile roofs that require specific flashing and standoff techniques to prevent leaks during the summer monsoon season.
Because only three of the top-rated solar companies on this list are actually based in Mesa proper, this guide includes highly rated contractors located in neighboring East Valley cities like Chandler, Tempe, Gilbert, and Phoenix. These shops sit between four and 21 miles from central Mesa. A reliable operator here knows the difference between APS and SRP interconnection queues, pulls City of Mesa permits without delays, and mounts hardware that survives August dust storms.

Before you hire in Mesa
Getting panels onto a roof in Mesa requires dealing with extreme heat, strict local utilities, and specific city building codes. A successful solar project comes down to hiring a contractor who understands the local grid rules and roofing types.
SRP vs APS interconnection
Mesa relies heavily on the Salt River Project for its grid power, though some fringe areas fall under Arizona Public Service. SRP operates with rigid demand charges for solar customers, meaning they bill you based on your highest half hour of energy usage during peak times. A contractor must design your system specifically for SRP rate plans, often requiring a battery backup to shield you from demand spikes. Ask the contractor exactly how many SRP setups they have passed through interconnection.
Clay and concrete tile roofs
Many neighborhoods in East Mesa feature concrete or clay tile roofs. These materials crack easily under foot traffic. The crew installing your array needs to use proper tile replacements and specific flashings. Ask if they use comp outs where they remove the tile under the array and lay down asphalt shingles, or if they drill through the tile. A sloppy installation will leak during the summer monsoons.
City of Mesa permitting
Every grid tied solar array in Mesa requires a building permit. The City of Mesa Development Services handles these applications, and they look closely at structural load calculations and electrical line diagrams. Check that the contractor pulls the permit under their own company name. If a salesperson asks you to pull the permit as an owner builder, walk away. That puts all the liability on your shoulders.
Heat degradation and equipment
Mesa summers regularly exceed 110 degrees. Solar panels lose efficiency as they heat up, a metric known as the temperature coefficient. Look for contractors who install tier one panels with low temperature coefficients. Additionally, string inverters mounted on south facing stucco walls bake in the sun. Ask the contractor where they plan to mount the inverter and if they recommend microinverters for better heat dispersion.
Electrical panel upgrades
Older homes in central Mesa often run on 100 amp or 125 amp main electrical panels. Modern solar arrays usually require at least a 200 amp panel to safely handle the backfed load. During the initial site visit, a competent installer will check your main breaker box. Ask if an electrical panel upgrade is included in their proposal or if that will be billed as a surprise change order later.
Understanding pigeons and critter guards
Rooftop solar arrays create a perfect shaded nesting area for pigeons. Once birds nest under the panels, their droppings damage the roof surface and block rain gutters. A local contractor knows this is a massive issue in the Valley. Verify that critter guards or bird netting are included in the original scope of work, not sold as an afterthought.
Questions people ask
Do I need a building permit for solar in Mesa?
Yes. The City of Mesa requires an electrical and structural permit for all grid tied solar installations. The contractor should handle all drawings and submit the application to Development Services on your behalf.
Does SRP buy back excess solar power?
SRP credits you for excess generation, but their current rate plans are heavily structured around demand charges. You do not get a straight retail credit for the power you send back. Many locals install batteries to maximize their savings under these rules.
Can my HOA block me from installing solar panels?
No. Arizona law prevents homeowners associations from banning solar panels outright. An HOA can dictate placement as long as their rules do not significantly reduce the system's performance.
Should I wash my solar panels in Mesa?
Yes. The summer dust storms leave a thick layer of dirt on the glass, which blocks sunlight and reduces output. Hosing them off early in the morning before they get hot can restore their efficiency.
How long does a solar installation take?
The physical installation on the roof usually wraps up in one or two days. The wait for utility interconnection and city inspections often stretches the total project timeline to several weeks.
Do I need a battery with my solar panels?
A battery is highly recommended if you are in SRP territory due to their demand charge billing. It allows you to store power and use it during peak evening hours when grid power is most expensive.
Will solar panels void my roof warranty?
Roof penetrations can void the warranty on that specific section of the roof if done incorrectly. Reputable contractors provide their own workmanship warranty covering the areas they drilled into. Check that their warranty covers roof leaks.
What happens to my solar panels during a power outage?
Standard grid tied systems automatically shut down during a blackout to protect utility workers fixing the lines. If you want backup power during an outage, you must install a battery system equipped with an automatic transfer switch.
