SunPower is one of the oldest and most successful solar companies in Arizona. It has been in business since 1985 and is known for high-quality equipment and some of the best warranty coverage available. This is also one of the most reputable solar contractors in Arizona.
SunPower panels usually cost between $2.85 and $3.25 per watt. Since Arizona residents typically need an 11.5-kW system to eliminate electric bills, you can expect to pay between $32,000 and $37,000 for your solar energy system. After the federal investment tax credit (ITC) is considered, that’s between $23,500 and $27,500, on average. This is well above the average for Arizona.
This company accepts cash purchases, solar loans, and no-money-down options like solar leases and power purchase agreements (PPAs). SunPower has a referral program through which you can earn $100 for each referred customer.
SunPower provides a 25-year comprehensive warranty that is superior to coverage from most other solar companies in AZ. It covers the equipment, energy production, and workmanship for the installation. This is exceptional, and it’s great to have in Arizona, where monsoons and other extreme weather can put your panels at risk of damage.
SunPower installs solar panels, electric vehicle (EV) chargers, and solar batteries and provides solar monitoring for all installed systems. SunPower only installs Maxeon solar panels, which are made by its sister company. This is one of the industry’s most efficient and sought-after solar panel brands.
SunPower does both in-house and contracted installations. It’s undergoing major internal changes and is converting to all in-house installations. For now, though, you could get either. Many of SunPower’s in-house installers are certified by the North American Board of Certified Energy Practitioners (NABCEP), and the company is accredited by the Better Business Bureau (BBB).

Verde Solar Power is a local company located in Cornville. As a small company, Verde can provide unmatched customer service and attention to each solar customer. It also has decent warranty options and provides top-level equipment at competitive prices.
Verde Solar Power doesn’t include average pricing for its systems online, but the costs are usually below average. This company only accepts cash purchases and solar loans. While it is quite affordable, the lack of leases and PPAs could dissuade some customers.
Verde Solar offers several solar equipment brands, including Solar Edge, QCells, Silfab, Canadian Solar, Schneider Electric, Fronius, Magnum Energy, Mission Solar Energy, and Solar World. It doesn’t provide access to some more popular brands, like SunPower, LG, Panasonic, or Tesla.

ADT has provided home security services to homeowners for decades, and it recently acquired SunPro Solar to expand its services to renewable energy. It’s a nationwide installer with outstanding overall warranty coverage and good quality.
ADT Solar is around average when it comes to pricing. You can expect to pay around $22,000 for a solar system in AZ when you choose this company (after the ITC is considered). It only accepts cash purchases and solar loans. It’s not a good option for solar leases or PPAs.
This company has one of the best referral programs in the industry, offering a $1,000 bonus for each referred customer. It also has a referral app that makes getting paid for referred businesses a breeze.
ADT is an industry leader in solar warranties. It provides a 25-year all-inclusive warranty that covers equipment damage and malfunction, workmanship, and solar panel power production.

Palmetto Solar is an outstanding national installer that offers full-service solar solutions and a wide range of additional options in Arizona, including home energy efficiency upgrades. It also offers a wide range of products and services and excellent warranty coverage.
Palmetto notes on its website that the average cost for its solar energy solutions is around $3.04 per watt. This would mean the typical 11.5-kW system in AZ would cost about $35,000 before the ITC. This is well above the average in the area and the country.
Palmetto includes a 25-year warranty for all equipment and for installation services. This is excellent, although there is no warranty or guarantee for power production or efficiency. Palmetto Solar keeps solar panel systems accessible by accepting all payment options, from cash purchases to solar loans, leases, or PPA.
Regarding services, Palmetto excels above most other companies in the area. It provides standard options like installations for solar panels, battery backup systems, and EV chargers. In addition, it offers:
Palmetto does have a team of in-house installation experts, but it often outsources projects to third parties to keep up with demand. This can sometimes lead to below-average customer service. Palmetto only lists Solar Edge and QCells as equipment brands it installs, but it can also get most equipment brands you’re looking for if you ask.
Palmetto Solar partners with Solar Sister, a Solar API Partnership with Exelon, and Get Solar Give Solar. The company is also accredited by the BBB and has several NABCEP-certified installers on its installation team.

Tesla is a well-known titan in the tech industry, and while it’s better known for its electric vehicles, it also has some of the top solar technology. There are some downsides to working with Tesla, like the sometimes below-average customer service, but overall the quality is good.
Tesla is a bit on the expensive side if you buy its products outright. However, the company offers price matching, which means it will reduce its equipment costs to match competitors in the area. This company only accepts cash purchases and solar loans.
Tesla outsources all of its installations to third-party companies. While this isn’t always bad, it can lead to issues with poor customer service. However, the company maintains some control over quality by only using certified installers. Tesla provides access to solar panels, batteries, roofing, EV chargers, and monitoring.

According to the Solar Energy Industries Association (SEIA), over 125 solar installers serve Arizona. This means you have your work cut out if you want to narrow down your options and choose one installer for your solar project. Picking a solar contractor will likely involve hours of research, which is very time-consuming.
Alternatively, you can choose a company we’ve reviewed above and have designated the best solar companies in Arizona. Our top pick is SunPower, a large company that services all of Arizona, provides outstanding warranty coverage, and installs high-efficiency equipment to help you take full advantage of the abundant sunlight in AZ.
Choosing a solar company is so complicated because there are many factors that you should consider in your decision, including local factors that are extra important in Arizona. We’ll discuss some of the more important considerations to make below.
Arizona residents usually require an 11.5-kW system to offset energy costs, which is larger than the national average. As such, prices will naturally be higher than average, so the cost is an important thing to think about.
Different solar panel companies have different price points for equipment and labor that can lead to differences of thousands of dollars for your entire system. We recommend choosing a few of our top picks for solar installers and getting free quotes from each to compare. It’s also important to consider the quality and value you get for the price.
Solar warranties cover equipment damage, performance, or installation quality, and some of the leading warranty options cover all three — like the ones from SunPower and ADT Solar.
The equipment warranty is important in Arizona because the state is prone to intense winds and blowing debris during monsoon season. A lengthy equipment warranty means peace of mind, even during extreme weather.
Many AZ homeowners also prioritize efficiency warranties, as energy consumption and energy prices are above average in Arizona. High-efficiency panels can make the best use of the intense and plentiful sunlight in Arizona, and they are more likely to eliminate your utility bills and save you more in the long run.
If you want solar panels installed, just about any solar company will suffice. However, many Arizona residents want solar batteries to provide power through the frequent blackouts in Arizona, most of which are caused by excessive strain on the electrical grid. If you want solar batteries, an EV charger, or other services, you can rule out any companies that don’t offer these options.
Given that solar panel systems in Arizona cost well above the national average, most solar customers cannot afford to pay cash upfront for their systems. If that’s the case for you, you’ll want to choose a company that accepts solar loans, at the very least. If you need a $0-down option or one that costs you the least upfront, choose a company that offers solar leases or PPAs. Remember that these last two options also save far less in the long run.
Solar energy companies have two choices for installations: complete them using an in-house team of installers or secure business and then outsource the installation to third parties.
Companies that install solar panels usually have better control over the process and can provide superior customer service. However, companies that outsource installations can usually afford to charge lower prices for equipment and labor, and they tend to have more flexibility for installation timelines.
In addition to having options for solar installers, you’ll also have many options for the solar equipment brands you can install in Arizona. If you know what brands you want based on their efficiency rating or the manufacturer’s warranty coverage, you can rule out installers that don’t carry them.
Reading through some online reviews for the companies you’re considering is a good way to confirm that the company will provide quality service and good communication throughout the installation process. Customer review sites like Google Reviews and Yelp can help weed out companies that seem great on paper but fall short when delivering on promises.
Arizona’s solar industry is booming, so the area is inundated with new solar companies to take advantage of the demand. Looking for industry partnerships is a good way to see behind the curtain. When solar installers align themselves with nonprofits and community and solar organizations, it’s a good sign that they’re in the industry for the long haul and stand up for their company values beyond profit.
Many solar customers don’t realize that the size of the company they choose can significantly impact their experience. Larger companies usually have more appealing prices and, in many cases, better flexibility for installations. However, smaller companies usually have a better handle on customer service and can sometimes provide better system customization options than national solar providers.
In our opinion, SunPower is the most reputable solar company in Arizona. SunPower has been around since 1985, and it has a long-standing reputation for providing best-in-class equipment and stellar warranty coverage. It’s a bit on the expensive side, but most customers agree that paying for quality and peace of mind is worth the investment. This is especially true in Arizona, where energy usage is high, and the risk of damage is present during monsoon season.
Solar panels are absolutely popular in Arizona. In fact, it’s the fifth most popular state for solar panel installations. The popularity of solar has gone down a bit over the past few years because Arizona removed its net metering policy in 2016, which was a great way to help solar customers eliminate their energy bills and save money. Still, the plentiful sunlight and other solar incentives continue to make solar a popular option in the Grand Canyon State.
Solar panels are designed to function and produce energy in all temperatures that you’ll experience in Arizona. Higher temperatures do reduce solar panel efficiency a bit, but the fact that AZ experiences around 300 days of sun per year — well above the national average of 205 — means there is still plenty of opportunity to offset your electric bills with solar panels.
It’s also worth noting that a lot of the energy consumption in Arizona goes toward home cooling. Solar panels absorb solar energy that would otherwise be absorbed by your roof and heat up your living space. Installing panels not only helps insulate your roof, keep your home cool, and reduce your energy needs, but it can also save you money on electricity at the same time.
Yes! In addition to the 26% federal solar tax credit, Arizona offers a residential solar tax credit for 25% of the system’s cost or up to $1,000, whichever is less. This helps further reduce the cost of going solar in AZ.
Yes, absolutely. For most customers, installing solar panels will provide energy savings that pay for the system within around 12 years and will then save over $20,000 on energy costs going forward. Arizona’s abundant sunlight and favorable solar laws help make solar an outstanding investment for most residents.
Most solar panels come with a 25-year warranty, but they typically last much longer. Provided yours aren’t damaged by the monsoons in Arizona, you can reasonably expect a lifespan of anywhere from 30 to 40 years or more in some cases.
Yes, solar panels will increase your home value in Arizona. The specific bump in property value varies, but Zillow estimates that your home will increase in value by over 4% after solar installation. Arizona also has a solar property tax exemption, which means this added value won’t cause your property taxes to go up.
Yes, the solar panel brand you install is important no matter where you live, but especially in Arizona. AZ homeowners have some of the highest energy bills in the country, which means a large solar system is usually required to offset electric bills. Choosing a high-efficiency panel — like Maxeon panels from SunPower — will often let you take better advantage of the available sunlight and maximize your savings potential.
Additionally, durable panels with a long equipment warranty are best to stand up to the extreme weather that hits Arizona in the summer months.
