This makes it the ideal place for harnessing solar energy power.

With nearly 300 solar companies in Arizona, finding the best provider may feel like an overwhelming task. To make the process easier, we at the Home Media reviews team have researched dozens of companies and created a list of the top solar installers in the state.

Palmetto Solar tops our list of solar companies because of its 25-year panel warranty and comprehensive protection plan. The company also provides extensive customer service options. You can communicate with customer service via chat, email, phone or the dedicated app. 

Palmetto has a detailed installation process that focuses on finding the best solar solution for each customer. From the initial consultation to the completed installation, the company keeps you well-informed throughout every step. Your new solar system will include monocrystalline solar panels, an inverter and an optional sonnen battery. 

The optional Palmetto Protect plan offers customers and non-customers additional monitoring and service options on a tiered scale. The tiers run from $8 to $49 per month, with options for yearly subscriptions for extra savings. The highest Premier tier includes 24/7 system monitoring, free annual panel cleaning or service visits and exclusive discounts for local service providers.

Alternatively, you can lease your solar panels. This means Palmetto will remain the system owner and be responsible for the maintenance and upkeep. You’ll pay a fixed monthly rate with little to no initial costs. You can purchase your panels or have them removed when your lease ends.

The fourth payment option, Palmetto’s power purchase agreement (PPA), allows you to pay only for the solar energy you use each month. Your monthly fee is based on the energy you use and can vary. After the agreement ends, you can purchase the system from Palmetto or have the company remove it. Both the lease and PPA options disqualify you from solar incentives and tax breaks.

Solar Incentives in Arizona

Arizona residents can lower the cost of their solar systems thanks to several tax credits and incentives available in the state:

    • Arizona Residential Solar Energy Credit: The Residential Solar Energy Credit allows residents to claim a tax credit of 25% of the cost of their solar system for a maximum of $1,000. If the tax credit is more than the amount you owe in taxes, the remaining credit will roll over to the following year for up to five years. Each household is limited to only one credit regardless of the number of qualifying solar energy devices onsite. 
    • Solar and Wind Equipment Sales Tax Exemption: The Solar and Wind Equipment Sales Tax Exemption prevents homeowners from having to pay sales tax on qualifying solar energy systems. This is limited to the system and does not include accessories like solar batteries. 
    • Energy Equipment Property Tax Exemption: This tax incentive exempts homeowners from paying additional property tax for the increased property value a solar panel system provides.

You can also apply for the federal solar tax credit and receive a 26% credit for the cost of your solar system. Your system must be installed by the end of 2022 to qualify. The credit reduces to 22% for all systems installed during 2023. If the taxes you owe are less than the credit, it will roll over to the next year for up to five years.

How To Choose the Best Solar Company

When searching for the best solar companies in the Grand Canyon State, consider the following factors.


Homeowners should verify that any potential solar company serves their area. Some companies advertise availability in a state, but their coverage area is limited to particular ZIP codes. For example, a company promoting its coverage in Arizona may serve residents in Tempe and Mesa but not in Peoria.


We recommend looking for solar companies that offer extensive warranties. The industry standard is about 10 to 12 years for an equipment (or manufacturer’s) warranty and 25 years for a performance warranty. Some companies go beyond the norm and offer 25 years for both types of warranties. Additional warranty benefits could include extended warranties for your add-ons, such as solar batteries and EV chargers, and coverage for roof damage or leaks due to solar installations. 

Panel and Add-on Selection

The availability of name-brand panels, inverters and other system add-ons varies from company to company. If you’re set on a specific brand for your solar project, look for companies that carry that option.

Some companies choose to manufacture their products in-house. Though this limits their variety, it adds a design advantage. Since they control the functionality of each component in the system, these individual parts can be designed to work better together. The result is a streamlined system engineered to work at peak efficiency. 

Also, keep in mind that premium panels come with a premium price tag. The higher the panel efficiency, the more you’ll have to pay up-front. However, investing in the highest quality panels you can afford will pay off in the long run. 

Company History and Brand Reputation

Some solar companies have been in business for decades, while others are simply established electronics and technology companies that have branched into clean energy. Companies with 15 or more years of business experience have a bigger advantage than newly established companies with less than five years of experience. As the popularity of solar energy continues to grow, so will the number of new solar providers hoping to cash in on the surge.

The Bottom Line: Which Arizona Solar Company Is Best for You?

Arizonans looking for the most comprehensive protection plan should consider our top choice, Palmetto Solar. If you want more flexible options for your solar project, including the ability to transfer your service to new homeowners, Vivint Solar may be a better fit. SunPower is the best choice for your home if you want to invest in some of the most efficient solar panels available. 

The best way to find the ideal solar installer is to do your research. Request quotes from at least three solar companies and compare their services, product options and customer reviews. Also, verify that any companies you’re considering are available in your area. 

Frequently Asked Questions About Solar Companies in Arizona

Methodology: Our System for Ranking the Best Solar Companies

We collected data on dozens of solar companies and created a comprehensive rating system to formulate our rankings, grade each company and provide objective findings to our readers. The result of weighing a wide range of factors is a cumulative score for each provider.

We called companies and spoke with representatives to understand their products, services and solar installation processes. We also reviewed each company’s product, production and workmanship guarantees in detail and closely examined customer reviews to understand the customer service experience with each provider.

All company data is monitored on an ongoing basis so that all rankings and information remain up to date.

Once we gathered all relevant data, we used the following scoring system to grade each solar company on a 100-point scale:

  • Solar services (25 points): Does the company provide in-house solar panel installation and battery backups? Can the company also monitor energy production and perform energy-efficiency audits to ensure system performance? The more options available, the higher the score. 
  • Warranty options (15 points): Warranties for products, system output and workmanship and the length of these guarantees are significant factors in residential solar system performance. Warranties vary by company, so we score companies based on the number of options available. The more warranties a company offers, the higher the score it receives.
  • Availability (10 points): Most solar companies are not available nationwide. We award the most points to companies with the most extensive service area and state availability.
  • Experience (10 points): We rate solar companies based on the number of years they have worked within the industry. The more years a company has been in business, the higher the score. 
  • Payment options (15 points): For each payment option the company provides, it receives more points. Options include purchase, loan, lease and Power Purchase Agreements (PPAs).
  • Reputation (10 points): We factor in each company’s score on the Business Better Bureau (BBB) and deduct points for any alerts or pending lawsuits.
  • Additional benefits (15 points): We evaluate solar companies based on added features and services such as a mobile app, virtual consultations, electric vehicle chargers and 24/7 live customer support. The more of these options a company provides, the more points it receives.
