How to Choose the Best Solar Company in Arizona

There are several key factors to consider when choosing the best solar company for your home in Arizona.

Design and Installation Processes

The design and installation process should be streamlined, efficient, and transparent. Ask your potential company about its design process, what factors it considers when designing a system for your home, and whether it uses high-quality materials during installation. Make sure the installation team is experienced, certified, and licensed in Arizona to ensure a safe and effective installation.

Financing Options

Many solar companies in Arizona offer financing options, including leases, loans, and power purchase agreements (PPAs). Before choosing a financing option, make sure you understand the terms, interest rates, repayment schedules, and any fees associated with the financing.

Equipment Quality

Solar panels, inverters, and batteries should be high quality and from reputable manufacturers. Ask the solar company about the brands of equipment it uses, if said tools are tested and certified for use in Arizona, and if they have any warranties or guarantees.

Customer Service

A good solar company should have a responsive and knowledgeable customer service team available to answer any questions you may have before, during, and after the installation. Check the company’s online reviews and ratings to read clients' experiences and ask any of your neighbors if they've used the company.


Ensuring your solar panels are functioning correctly is crucial for maximizing energy savings. We recommend looking into Arizona solar companies that offer monitoring services, which allow you to track your system’s performance, spot any issues, and ensure that you’re getting the maximum return on your investment. A variety of companies offer 24/7 monitoring (some at an additional cost), so make sure to ask when speaking to a representative.

Warranty Length

A longer warranty can provide peace of mind and may save you money in the long run. The typical industry standard is 25 years, but you should still ask about the length of the warranty for panels, inverters, and any other equipment as this may vary depending on the company. Additionally, some things to ask include if your warranty covers parts and labor, or just just one of these aspects.


Arizona offers several solar incentives to reduce your upfront costs or provide ongoing savings, but beware that most PPAs and solar leases may not allow you to access these incentives. Look for solar companies in Arizona who are knowledgeable about the state’s incentives like federal solar tax credit, rebates, and net metering programs.

Average Cost of Solar Products in Arizona

To estimate the cost of installing solar panels in Arizona, homeowners can determine their average energy usage by looking at their power bills to see how many watts or kilowatts they need. The average cost per watt for solar panels in Arizona varies depending on the type of panel and product, but it can be estimated at around $2.82 per watt. For most homes, this translates to a total cost of between $11,000 and $17,000 for a system that generates between 4kW to 6kW of energy. 

It’s important to note that additional costs can arise if homeowners choose to install a battery backup, such as Tesla’s Powerwall, which costs $11,500 per unit and provides between 5.8 kW to 10 kW of power. Depending on the model, Enphase’s IQ batteries are a more affordable option, costing between $3,000 to $6,000 per unit.

Do note that Installation and labor costs can further add anywhere from $1,000 to $5,000 to your final price. Due to the high cost of solar installation, many homeowners opt to take out solar loans or lease their solar panels through a PPA. However, it’s important to carefully review all terms and conditions before committing to a solar panel company to avoid feeling trapped by the agreement’s terms.

Do You Need Approval to Install Solar Panels in Arizona?

In Arizona, a permit is generally required to install solar panels. This is issued by the city or county where the installation will take place. The process of obtaining a permit typically involves submitting an application which includes a description of the proposed solar panel system, and paying a fee. Homeowners should ensure that the installation company is aware of the permit requirements and can handle the application process. The Arizona Corporation Commission provides additional information and resources for homeowners regarding solar panel installations and permits.

Are There Tax Incentives for Going Solar in Arizona?

Arizona offers a residential solar energy credit of up to $1,000 for homeowners who install solar panels on their primary residence. Additionally, Arizona has a property tax exemption for residential solar panel installations, which means that the added value of the solar panels to the property will not increase your property's taxes. The federal government also offers a tax credit of up to 26% of the cost of the solar panel installation. Homeowners should consult with a tax professional to ensure that they are eligible for these incentives.

Frequently Asked Questions

  • Who is the largest solar installer in Arizona?

    The largest solar installer in Arizona depends on the metric by which you measure it, but by most accounts, it is Sunrun, which offers solar panel installation, financing, maintenance, and comprehensive monitoring. With more than 15 years of experience, Sunrun is a leader in the residential solar installation industry. It has over 285,000 solar and battery system installations in 20 states, including Arizona, where it has established a significant presence.

  • Is it worth it to switch to solar power in Arizona?

    Arizona’s abundant sunshine and favorable net metering policies make it an attractive state for solar power. The cost of solar installation has decreased significantly in recent years, making it a more accessible option for many households. Additionally, there are several tax incentives available to Arizona residents which can reduce the overall cost of installing solar panels. However, every homeowner should conduct a cost-benefit analysis to determine if solar is a worthwhile investment for their specific circumstances.

  • How long do solar panels last in Arizona?

    Solar panels are designed to last for several decades, and in Arizona—where the weather is dry—they can last up to 25 or more. The longevity of solar panels is dependent on several factors, including the quality of the panels, the installation process, and the maintenance performed over the years. Homeowners can extend the life span of their solar panels by scheduling regular inspections, cleaning, and repairs by a professional installer. Most solar panel manufacturers offer warranties that cover the panels for up to 25 years or more, which should cover the life span of your solar panels.

  • Do solar panels need to be cleaned in Arizona?

    Solar panels should be cleaned once or twice a year to maintain their efficiency and maximize energy output. The dusty desert environment in Arizona can cause debris, pollen, and dust to accumulate on solar panels, which can reduce their ability to absorb sunlight. Homeowners should hire a professional to clean their solar panels to avoid damaging them or voiding the manufacturer’s warranty.

  • Do solar panels increase property value in Arizona?

    Studies have shown that homes with solar panels increase in value compared to homes without them, especially in areas with a high demand for renewable energy. The exact amount of value that solar panels add to a home can vary depending on the size and quality of the installation, as well as the location of the property. Homeowners should research the real estate market in their area to determine the potential impact on their property’s value.

  • How do you qualify for free solar in Arizona?

    Several programs available in Arizona offer free solar panels to homeowners who qualify. One such program is the Arizona Public Service (APS) Residential Solar Program, which provides free solar panel installation to qualified low-income homeowners in the APS service area. GRID Alternatives Arizona also offers free solar installations to eligible homeowners who meet income guidelines. Additionally, some nonprofit organizations and community groups may offer free solar panel installations to qualifying homeowners.
