Arizona is a solar powerhouse — with some of the best sun exposure in the country and rapidly rising electricity rates, going solar is practically a no-brainer. From Phoenix to Tucson to Flagstaff, homeowners are making the switch to cut costs, gain independence, and prepare their homes for summer heat and monsoon outages. With strong state support and federal tax credits, solar in Arizona offers some of the best ROI in the nation.
Choosing the right installer matters just as much as choosing to go solar in the first place — the difference between a company that’s licensed, experienced with Arizona’s net billing rules and utility-specific rate plans, and backed by a real workmanship warranty and one that isn’t can add up to thousands of dollars over the life of your system. Below, you’ll find Arizona’s solar companies compared side by side, including which ones have completed EnergyScout’s verification process, so you can start your search with a shorter, more confident list.
EnergyScout tracks local and national solar companies serving homeowners throughout the state. Use the directory below to compare installers based on experience, service area, products, certifications, and other company information.
Companies displaying the EnergyScout Verified badge have completed an additional review process that includes a direct interview, screening customer feedback, and providing evidence of completed installations. Verification provides another layer of information when comparing solar companies, but homeowners should still evaluate multiple installers to find the right fit for their home.

Arizona’s Solar Advantage:
Arizona ranks #3 in residential solar installations and has over 9,400 MW of total solar capacity installed statewide. The state receives more sunshine than almost anywhere else in the country — Phoenix alone averages over 300 sunny days per year — making solar panels incredibly productive. Arizona homeowners typically see excellent energy production year-round, with peak performance during the long, hot summers when electricity demand (and costs) are at their highest. The state’s solar industry employs nearly 10,000 workers, and installation costs have dropped significantly over the past decade, making solar more accessible than ever.
Electricity Costs and Solar Economics:
Arizona’s major utilities — APS (Arizona Public Service) and SRP (Salt River Project) — have been steadily raising rates, particularly during summer peak hours when air conditioning usage soars. Both utilities use time-of-use (TOU) rate structures, meaning electricity costs more during afternoon and early evening hours when solar panels are still producing. This alignment makes solar exceptionally valuable: you’re generating power exactly when it’s most expensive to buy from the grid. Arizona also offers strong net metering policies (though they’ve been adjusted in recent years), allowing homeowners to send excess solar energy back to the grid and receive credits on their bills. Arizona delivers some of the best solar ROI in the nation.
Preparing for Extreme Weather:
Arizona isn’t just hot — it’s extreme. Summer temperatures regularly exceed 110°F in Phoenix and the Valley, putting enormous strain on the grid and driving up electricity usage. Monsoon season brings intense storms, high winds, and occasional power outages. Solar panels are built to handle Arizona’s harsh conditions (heat, dust, UV exposure), and when paired with battery backup, they provide critical resilience during grid failures. Whether it’s a summer brownout or a monsoon outage, solar + storage keeps your home comfortable and powered when it matters most.
