Top Solar Companies in Phoenix: 2026
If you're shopping for solar in Phoenix, the good news is you have plenty of options worth comparing. While we won't crown any single provider as the best, we can tell you what the numbers look like here so you can judge quotes for yourself. In Phoenix, the average solar system size comes in at 8.8 kW. Homeowners purchasing a system in 2026 should be aware that the federal residential solar tax credit (Section 25D, IRS) expired for systems installed after December 31, 2025, and no federal credit applies to a new purchase. If you opt for a solar lease or PPA instead, the installer may pass through savings from the 30% commercial credit (Section 48E, IRS), which they can claim provided construction begins before July 4, 2026, or the system is in service by December 31, 2027. Arizona also offers a 25% state tax credit. On top of that, Phoenix benefits from net metering at full retail value. To put cost in context, the median household income in Phoenix is $72,000, so for many families this is a meaningful purchase that deserves careful thought. The smartest move is to gather several quotes, compare them side by side, and read the fine print on every contract before signing. Ask each company to break down the system size, the total price, and how the applicable incentives factor into your estimate. Talking to more than one provider helps you spot outliers and make a confident, well-informed decision rather than rushing into the first offer you see. This is general information, not tax advice.
Why a 8.8 kW Array Pays Back in 8.4 Years in Phoenix
An 8.8 kW array makes a lot of sense in Phoenix because of how hard your air conditioner works from May through September. With sunlight this abundant, a system that size typically offsets the bulk of a Valley home's annual usage, and the savings stack up fast against rising APS and SRP rates. It's important to know that the federal residential solar tax credit (Section 25D, IRS) expired for homeowner-purchased systems installed after December 31, 2025, so buyers in 2026 should not count on a federal credit reducing their upfront cost. If you go the route of a lease or PPA, the installer may pass through savings from the 30% commercial credit (Section 48E, IRS), which they are eligible to claim. Arizona's state credit and the sales tax exemption on solar equipment remain in place and still contribute meaningfully to shortening the payback timeline. From there, the math is straightforward: avoided electricity bills combined with those remaining incentives continue to work in your favor. The reason Phoenix payback beats most of the country comes down to sun. You're generating more kilowatt-hours per panel than homeowners in cloudier regions, so every dollar invested works harder here than almost anywhere else in the nation.
