Ensuring everything will be in working order is extremely important when choosing a solar company. It’s a long-term relationship, not one that ends after the ink dries on your sales contract.

  • Types of Products: Solar panels, solar batteries, and EV chargers
  • Warranty Information: 10-year workmanship warranty, 10-year roof penetration warranty, and manufacturer’s warranty
Pros & Cons

  • In-house teams handle everything from sales to installation

  • Offers 24/7 live customer chat and limited after-hours service for emergencies

  • System monitoring by the company costs extra

  • Doesn’t service Tucson

Why We Chose It

Sun Valley Solar Solutions makes the switch to solar an attractive proposition for Arizona homeowners by combining excellent customer service with top-of-the-line technology and competitive pricing. The company services the greater Phoenix area and all regions within a two-hour drive except for Tucson. If needed, a company representative will be able to recommend local Tucson installers. 

Sun Valley’s product portfolio includes reputable brands such as SunPower, REC, and SilFab Solar. The company's experienced in-house team will help build an entire system with panels, inverters, and batteries for your home, and install it with care. Once installation is complete, homeowners will have a 10-year warranty for workmanship and roof penetration, which should cover any unforeseen damage caused by the installation. For more expansive monitoring, Sun Valley provides 24/7 monitoring for an additional annual fee. 

While there isn’t any pricing information available online, the cash payment structure is split into three payments. The first is a $1,000 deposit when you sign the contract, then an 80 percent payment is required at the time of the installation, and the remaining 20 percent is due after you receive a “permission to operate” (PTO) from your utility company. Additional financing options include $0 down loans, home equity financing, and leases.

Best Upfront Pricing : Sunny Energy

Key Specs
  • Locations: Greater Phoenix area
  • Types of Products: Solar panels, solar batteries, EV chargers
  • Warranty Information: 25-year workmanship, labor, and production warranty
Pros & Cons
  • Offers instant online quotes with solar system specs

  • Financing options available with up to 25-year repayment terms

  • Online customer portal to easily manage your project and account

  • Limited selection of solar brands available

  • Specific financing information is not offered online

Why We Chose It 

Oftentimes, it can take days to receive a response after you have submitted your initial information for a solar panel quote. Sunny Energy breaks this cycle by offering an online quote tool that gives you a rough estimate in just a few minutes based on your address, average electric bill, and specific energy goals. The quote will detail the size of the system (how many panels), the expected energy output, specific solar brands, battery additions, and information about the warranty.

Pricing is competitive within the region, and the company offers a variety of financing options with five to 25-year repayment terms. The instant quote tool will show the different loan rates available. However, specific information about the financing opportunities is not offered online, so you will need to speak to a representative about the options at your disposal. One thing to keep in mind is that leasing solar panels is not a service offered by this company. 

In terms of product variety, Sunny Energy offers REC solar panels (a reputable Tier-1 brand), but other options are limited and subject to availability. Do note that customers will mostly be beholden to REC if they work with Sunny Energy. Regardless, all equipment comes with a 25-year production guarantee to ensure your system produces the amount of energy it’s supposed to for the next two decades, and a 25-year product and labor warranty as well.

Best Warranty : SunPower

Key Specs
  • Locations: Throughout Arizona
  • Types of Products: Solar panels and solar batteries
  • Warranty Information: 25-year product, labor, and performance warranty, and also 10-year hardware monitoring warranty
Pros & Cons
  • SunPower Design Studio allows clients to view solar panel system

  • Highly energy-efficient solar panels

  • Offers different financing options to consumers

  • Installation and repairs performed by third-party companies

  • More expensive than average

Why We Chose It 

Solar systems are the type of investment that doesn’t give you a return until a few years down the road, so it’s important that your equipment is backed by a solid warranty. In this regard, SunPower has you covered, as the company’s products are all covered by a 25-year product and performance warranty. This ensures that your system continues to provide the energy output it’s supposed to, and any repairs or replacements are at no cost to you.

The company also has a 25-year labor warranty that guarantees any repair you need is free. In addition to its generous warranties, SunPower systems are very efficient and can provide the same amount of energy output as other brands, even while using fewer panels. This is a great solution if your roof is small, or you only have a limited area without shade.

The downside to this service is that the company tends to be a little pricier than average, but it does offer various financing options if you require them. Do note that SunPower does not install its solar systems itself, but relies on a network of authorized local dealers to complete the setup for you. Even though the dealers are vetted and recommended on a tiered basis, customer experience and service will vary according to the provider.  

Best Battery System : Tesla

Key Specs
  • Locations: Glendale, Scottsdale, Mesa, Tempe, Tucson
  • Types of Products: Solar panels, solar batteries, solar roofs, and EV chargers
  • Warranty Information: 25-year performance guarantee and 12.5-years inverter warranty
Pros & Cons
  • Makes and sells one of the best battery systems on the market

  • Gives thorough, instant online quotes

  • Has a price match guarantee and commitment

  • Can’t add more solar panels to a system after purchase

  • Doesn't install EV chargers

Why We Chose It 

Batteries are a crucial component of solar systems because they allow you to store excess energy and use it when there’s no sunshine for your panels to make electricity. This will allow you to rely less on a utility company’s power grid, and use energy directly produced from your own panels. One of the leading battery systems on the market right now is called Powerwall, which is made by Tesla

Tesla’s solar systems are sleek and well designed, on par with the aesthetics of the brand. Currently, the company is aggressively pursuing the solar market, declaring it will offer you the “lowest price of any national provider,” and backing that promise with a price match guarantee. You can get an instant quote online through its website by sharing your address and the average amount of your electric bill. You’ll see the price before and after incentives, and also the cost for a cash purchase versus a monthly loan. 

Aside from solar panels and Powerwalls, Tesla also offers EV chargers and solar roofs. The solar roof consists of solar glass tiles for energy generation and steel tiles to combat corrosion. Solar systems, roofs, and panels all come with a 25-year product and performance warranty to ensure your system will be functioning properly for the foreseeable future. While Tesla installs its own solar systems, it does not install its EV chargers, requiring you to hire an electrician to do it for you.

Best Energy Saver : Elevation Solar

Key Specs
  • Locations: Greater Phoenix area and Tucson
  • Types of Products: Solar panels and solar batteries 
  • Warranty Information: 25-year manufacturer’s warranty and 30-year product and performance warranty for additional cost
Pros & Cons
  • Conducts energy audit before installing solar panels

  • Offers energy efficiency packages to insulate and seal air leakages

  • Lets you keep track of your home’s energy usage

  • Warranty extension costs extra

  • Cancellation fee is $1,500  

Why We Chose It 

The goal for many solar homeowners is to reduce their electric bills and maximize the energy efficiency of their homes. Elevation Solar, an Arizona-based company, makes this a reality with a slate of services geared toward improving the energy efficiency of a property. Its most comprehensive package, dubbed the “Elevated Home,” bundles solar with an energy efficiency service and a proprietary energy monitoring system called Curb.

The purpose of this home solution is to help you detect and eliminate energy leakages to reduce energy usage before installing a solar system. Ideally, this may result in needing fewer panels, allowing you to save on costs. However, you are free to choose separate services outside the bundling option as well. For example, if you've already performed an energy audit and are seeking to install a solar system and batteries, you can do that too.

Once a system is fully installed, Elevation’s Curb energy monitoring system connects to your home’s electrical system to track your energy usage by room and appliances. Elevation works with Tier-1 solar panels like REC and QCells, and offers the manufacturer’s standard 25-year labor and product warranties, with an option to upgrade your warranty up to 30 years for an extra cost. However, if at any point you change your mind, there is a $1,500 penalty fee for cancellations.

Best Lease : Sunrun

SunRun logo


Key Specs
  • Locations: Throughout Arizona
  • Types of Products: Solar panels, solar batteries, and EV chargers
  • Warranty Information: 25-year maintenance, product, and performance warranty for leased equipment, manufacturer’s warranty for purchased panels, and 10-year roof penetration warranty
Pros & Cons
  • Every lease contract includes free solar system and installation

  • Online instant quote tool offers and compares leasing, purchase, and financing costs

  • Financing options available for installation

  • Leases do not qualify for federal tax credits and other solar incentives

  • It’s very difficult to cancel lease after solar system install

Why We Chose It 

As one of the biggest solar companies in the nation, Sunrun has ample experience selling and installing solar systems in a variety of environments. It also stands out because it has one of the most popular leasing products for solar systems with $0 down. Leases are a controversial service in the solar industry, partly because since you don’t own the equipment, you don’t qualify for the federal tax credit and other solar incentives designed for solar homeowners. However, in states like Arizona, where the break-even point of purchasing your own solar panels is too far into the future, it’s a viable alternative for someone hoping to save money on their electric bills.

When you sign a leasing contract with Sunrun, the company takes charge of installing the solar system, and provides all the necessary maintenance free of charge for the duration of your lease (typically 25 years). With a lease, you are only responsible for the monthly payment agreed upon during the sales process. But depending on your contract terms, your monthly payment may increase a couple of percentage points every year.

It’s important to note that if you sell your house, you have the option to transfer the lease to the new homeowner or buy the equipment outright if the buyer doesn’t want it. It’s very difficult to cancel the lease once the panels are on your roof. If the economics of the leasing agreement doesn’t make sense for your situation, you can still buy a solar system from Sunrun. The company has an online instant quote tool that lets you compare the cost of leasing versus buying and financing a solar system based on your address, energy usage, and roof specifications.

Final Verdict

Sun Valley Solar Solutions is a homegrown experienced solar company that offers competitive pricing, excellent customer service, and reasonable financing options that make sense for customers. Working with a solar company that has a proven success record and is knowledgeable about the region is a good way to ensure a successful solar outcome for your home. However, it’s also important to always gather at least three separate quotes to evaluate your options and choose the company best suited for your specific situation.

Factors to Consider When Choosing a Solar Company in Arizona

Deciding on the best solar company in Arizona is always going to boil down to your individual experience. Some companies are better suited to install solar panels on clay tiles, while others may be more experienced with concrete roofs. Here are some factors to consider when making your decision: 

Years of Experience 

The solar industry is growing, which means new entrants are regularly entering in the space. However, when choosing a provider, go for a company that has been in business for at least eight years or longer. While it is not a foolproof metric, it shows the company is capable of doing a well-enough job to stay in business for a long time. It is also more likely that you will have fewer issues with an experienced installation crew than with a company that's recently broken out on the scene. 

Product Portfolio  

The brands you choose for your solar system will have an impact on its performance and durability. Tier-1 brands are usually regarded as the most energy-efficient and sturdy enough to last for at least 25 years. Some Arizona Tier-1 brands include SunPower, REC, SilFab Solar, and Tesla. 


An important factor during the installation process is communication and reliability. Typically, a solar project can take a few months from signing the contract to having an operational system, but there are times when customers may have to wait longer. A reliable solar provider will keep you in the loop throughout the process and maintain its deadlines. 

Included Services 

Every customer has different needs, and some companies are better suited to accommodate that. For example, you may want to have an energy audit before installing a solar system but your preferred solar company doesn’t offer that service. Additionally, some companies include free 24/7 monitoring of your system with your purchase, while others provide it for an extra cost. Compare your options and choose the company that has the services you need. 


Solar systems are an investment, so having a strong warranty to protect that investment is a must. Most solar systems are backed by the manufacturer’s warranty, and depending on the brand you chose, the warranty can last as long as 25 years and cover labor, product, and performance. However, some solar companies choose to complement or extend those warranties when you work with them, sometimes for free and at other times for a fee.

Check your warranty options before you book anything, and do not work with companies that are not willing to offer an install or roof penetration warranty as part of their services. Installing a solar system often requires drilling holes through your roof, so it is critical that you ensure that the company covers any damage caused by the installation.   


Figuring out a reasonable price for a solar system for your home requires that you get multiple quotes from different vendors. Always try to compare the same brands across providers, or at least comparable system sizes and features to understand the cost of a tailored system. Remember, this is a very competitive space at this time, so if your preferred vendor has a higher price than others you’ve received, you could ask for a price match and see what they say.  


Since going solar requires such a big investment upfront, many solar companies have partnered with lenders to provide accessible financing options for people who may otherwise not be able to afford a system. However, pay close attention to the financing terms offered. In some instances, there are hefty fees which can increase the final price by as much as 30 percent. Always check with your financial advisor to find out what your best options are.  

What Solar Products Are Available in Arizona?

You can get a variety of Tier-1 solar brands in Arizona, including REC, SunPower, SilFab Solar, and Tesla. These brands manufacture energy-efficient solar panels that make up the core of a solar system. Additionally, you can find top-of-the-line batteries like Tesla’s Powerwall to complement your system and provide a backup during blackouts or when your panels are at full capacity.

Other solar products you may be able to find that don’t require any installation are likely solar energy plans from utility companies. In the case, you'll choose to buy electricity produced from an independent solar system.   

What Impacts the Cost of Solar Products in Arizona?

The cost of solar products in Arizona depends on the size of your system (how many panels), the brands you choose for your equipment, the inclusion of a battery system, your home’s energy needs (or your average utility bill), and the number of home amenities that consume electricity on a daily basis. All these things are specific to the cost of the solar system. However, there are other considerations you need to pay attention to.

For example, if you don’t have a battery for your system, or if your system isn’t designed to offset 100 percent of your electric needs, you may have to pay a higher rate to use your utility’s electricity whenever your panels are not producing energy. The rate you pay depends on your provider, and because these providers are locked into certain areas or regions, you may be stuck paying higher fees.  

Does Arizona Have a Solar Tax Credit?

Yes, Arizona residents can get a $1,000 income tax credit or 25 percent of the total cost of buying and installing their solar system, whichever is less. They are also eligible to apply for a federal solar investment tax credit of up to 30 percent. Additionally, Arizona has a tax exemption for property taxes when it comes to solar systems, so you don’t need to pay extra property taxes if the value of your home goes up for installing solar.

Frequently Asked Questions

  • How Much Does Solar Installation Cost in Arizona?

    The price for installing solar panels depends on a lot of factors, including but not limited to the size of your home, the energy you consume, and if you have a pool or an electric vehicle (or both). Generally speaking, if your average electric bill runs about $200 per month, you may be looking at $25,000 and above for a system without any batteries installed. Always get at least three quotes from different providers to compare your options and choose the best one for your situation.

  • How Long Do Solar Panels Last in Arizona?

    Solar panels in Arizona are designed to last for 25 to 30 years. However, extremely hot temperatures like the ones experienced during Arizona summers make solar panels less efficient. This is why it’s so important to choose a company that will offer at least a 25-year product and performance warranty to protect your investment long-term.

  • Do Solar Panels Increase Property Taxes in Arizona?

    No, the Energy Equipment Property Tax Exemption in Arizona states that the cost of your solar system won’t be factored in when determining your property taxes. While your home’s real estate value might go up after you install a solar system, your property tax will not.

  • How Do I Qualify for Free Solar in Arizona?

    The concept of “free solar” refers to solar systems purchased through a loan with $0 down. While you’re still paying for the system, you’re doing it in bite-sized monthly installments rather than a lump sum upfront. Each lender will have its own specific terms, and you need to submit an application to find out if you are eligible. However, generally, anyone with a 650 credit score and above can qualify for a solar loan.

  • What Is the Downside of Solar in Arizona?

    Financial incentives for going solar are smaller than in other states. Electric energy in Arizona is affordable and reliable for every season except for summer, where it is customary to keep the AC on full blast to combat temperatures of over 100 degrees. One of the largest downsides to solar in general—not just specific to Arizona—is that it could take a decade or more to see a return on the investment.

  • Do Solar Panels Require a Lot of Maintenance?

    Normally it is recommended to clean and perform routine maintenance every year. However, if your area is experiencing extreme weather like severe dust storms or wildfires that can deposit debris on your roof, maintenance frequency will be higher.


We determined the best solar companies in Arizona by collecting data points based on an extensive set of criteria, ranging from financing options to warranties. Our team reviewed 16  companies, rating them in the following categories:
