      2x Award Winner
      Selected for having one of the highest satisfaction rates for Best Customer Service and Best for Installation

      SunPower is a top national company that uses high-efficiency solar panel technology. We like that its SunVault storage battery is excellent for maximizing energy savings during peak rate times.

      What really sets SunPower apart is its seamless solar panel installation process. Local reps can evaluate your home energy needs, design a custom system, help secure any necessary permits and work out financing options. They work with local installers on Utah projects, and SunPower’s monitoring app lets you track the system’s performance once everything is complete.

      "The installation, the communication and the salesperson were excellent," Dawn in Mesa told us. She also likes the monthly savings — her monthly bill is about half what it used to be.

      Robert in Sedona had a similar experience: “On the first month that we got SunPower, the bill was $3 and in addition to that, there was a note that said we saved an entire time of carbon equal to what it would normally have been released.”

      Others highlight the smooth installation process. “The system has been trouble-free. It's generating power like it's supposed to. I'm running two houses on the same bill and I hardly ever get a bill,” Michael in Chino Valley told us.

      Brian in Buckeye, who considered other companies first, said SunPower was "the only company to be upfront about certain costs." For Don in Tucson, "the reliability and warranty of the equipment" made SunPower stand out.

      SunPower-certified installers handle installation jobs, and systems come with a comprehensive solar warranty that includes all components.

      The company offers various financing options and has a broad international dealer network. However, dealers may provide different levels of service.

      • 35-plus years of experience
      • Comprehensive 25-year warranty
      • Battery storage options
      • Energy monitoring services
      • Leasing and financing

      SunPower is a reliable solar company with comprehensive services, but it’s not always the cheapest option. Your upfront costs tend to be a little higher than other companies. If you’re on a tight budget, we suggest comparing SunPower to a few other options.

      We also hear about occasional communication challenges. Most communication happens over email. So, if direct, in-person conversation is important to you, consider working with a smaller operation or hiring locally.

      SunPower’s “Complete Confidence Warranty” covers your entire solar energy system for 25 years, including the panels, inverter, racking and monitoring. Solar panel models have varying power output protection for 25 years:

      • M-Series (SPR-M), A-Series (SPR-A), X-Series (SPR-X), E-Series (SPR-E): All have a maximum annual decline of 0.25%, with a minimum of 92% energy performance.
      • The U-Series (SPR-U): Has a maximum annual decline of 0.55%, within a minimum of 84.8% energy 

      There’s also a 10-year warranty and unlimited cycles for SunVault storage. During this period, the company repairs or replaces equipment at no cost to you (including labor and shipping). SunPower’s warranty terms allow for beachside installations and system relocations.

      You can pay cash for a system, but many customers decide to lease or finance through a solar loan instead. We like that SunPower’s payment terms are clear and focus on invoicing and dispute resolution.

      • Loans: Qualified customers can find reasonable rates with no money down. All financing approvals and processing happen through the mySunPower online portal.
      • Leases: Customers pay a monthly fee to use solar panels that SunPower owns. SunPower reimburses you if your solar system doesn’t perform as guaranteed. If you sell your home, you can transfer the agreement to a new buyer.

      You can reschedule delivery under any at no charge as long as it’s within 30 days of the original delivery date. Beyond that, there is a penalty fee.


      • Great professional installation services
      • Highly efficient equipment

      Sunrun solar advisors use proprietary design technology to analyze your home and energy needs. Once you finalize the design, Sunrun submits all necessary paperwork for approval from your local government. After the system is approved, installation can begin. It usually takes one to five days to complete.

      Sunrun's leasing program is a great way to get solar panels without the huge upfront investment. You don't have to pay for the equipment, installation, permitting or financing costs. Sunrun owns your system, and you pay a fixed monthly fee to use it. Lease agreements typically last 25 years.

      Sunrun benefits

      • Easy to get started
      • Custom solar designs
      • Daily system monitoring
      • Smart technology
      • Free maintenance plans available

      “Everything was smooth, and the team was really on top of my installation. If I had any questions, they answered it,” Felicia in Phoenix told us. “So far going solar has been good. The system has been turned on for a few months, so we're still seeing the effect of it. But we're happy with it.

      Some praised Sunrun for its easy enrollment process and savings on their electricity bills, like Patrick in Phoenix. "They have a good model," Patrick said. "They didn't try to oversell me as some other companies did." He also likes that he's saving money and doesn't have to worry about maintenance. "There's been zero issues with the equipment. It's been self-sustaining up to this point," he said.

      Another verified customer, Jose in Tucson, is confident he got the “best package for my electric needs” through Sunrun. "The packages they offer are golden amidst rising electric costs," he said.

      Sunrun sells and leases customized residential solar energy systems and its battery storage service in 20 states and two U.S. territories. Customers can own or lease a system with $0 down. Sunrun offers free energy consultations and quotes. Over 830,000 homes across the have gone solar with Sunrun, according to the company.

      • Professional solar panel installation
      • Support for new home builders
      • Solar storage battery options
      • EV charging solutions

      Sunrun works with subcontractors all over the country, and there's always the chance of miscommunications on big solar projects, especially with Arizona Public Service inspections. For example, Debbie in Sun City said there was a discrepancy between her Sunrun contract and what Titan Solar, the installer, accomplished.

      Installation took several weeks, and the system failed an initial inspection because of wiring issues, according to Debbie. “Then (it) had to be reinspected by (the) county, and then APS wouldn't pass it because they didn't install the sub-panel in the plans they had given APS," she said.

      Another customer, Joseph in Peoria, told us some reps might exaggerate potential cost savings. “I was told once I switched my highest APS bill would be $20-$25 a month. During the summer I’m paying APS $300-$450 a month. Plus $193 to Sunrun,” Joseph said.

      Sunrun has warranty coverage, system maintenance and a performance guarantee. Compared with SunPower, Sunrun’s warranty appears to more strictly limit its liability. However, that’s less relevant if you lease a system. Sunrun maintains ownership of leased systems, and so you don’t have to worry about paying for any repairs or maintenance.

      The warranty covers workmanship and equipment for 10 years. The performance guarantee lasts 25 years. Leased systems typically come with free maintenance and repairs. Its terms and conditions focus on service use, including account registration and payments, with a general "as is" disclaimer without detailed warranty specifics in the provided sections.

      As of publishing, available discounts include $0 down for some financing plans. You can lease solar equipment for a minimal upfront payment. Sunrun’s leasing plans are what really sets it apart from other solar options in Arizona:

      • Monthly plan: You can lease Sunrun panels for $0 or little down. Then, you pay a fixed monthly payment for the term of your leasing contract, typically 25 years.
      • Full amount lease: You can prepay for up to 25 years of solar energy.

      Project Solar

      Max. panel efficiency
      Payment options
      Cash, loan
      25 years
      Year founded

      Project Solar appeals to budget-conscious homeowners who want a less sales-heavy approach. Its salespeople don’t work on commissions. Instead, they can focus on a simple, streamlined customer experience. The company’s solar systems incorporate equipment from reputable brands like Q-Cell, Jinko and Enphase.

      We also appreciate the price transparency. As of this publication, full-service installations start at $1.61 per watt. DIY projects are cheaper, starting at $1.26 per watt. Anything over 13 kilowatts is a flat rate.

      “My experience was very good,” John in Mesa told us. “I put the order in and they took care of everything.” The installation took a little longer than expected, “but I was able to track the progress via the website, which was very convenient and the install went very smoothly,” John said.

      In general, people really like that reps are knowledgeable and able to answer their questions. Project Solar also gets excellent feedback about pricing.

      Project Solar specializes in residential solar panel installations. As part of the full-service installation, it offers Enphase IQ 5P batteries or Tesla Powerwall. DIY projects only have the Enphase IQ 5P option. The website provides clear information on pricing models and potential savings.

      • System design
      • Equipment procurement
      • Pro and DIY installations
      • Financing solutions

      John in Mesa said his one complaint was how long it took: “I put the order in in September and it took until May for everything to get turned on. Customers in other states also occasionally tell us about installation delays or inconsistent communication.

      Project Solar provides two main warranties: a 25-year manufacturer’s warranty and a 10-year workmanship warranty. It also has an 84% production guarantee for 25 years and provides reimbursements if production levels are not met during this time.

      The manufacturer's warranty covers defects in materials or workmanship of the solar panels, inverters and other equipment. The workmanship warranty covers installation issues (like faulty wiring or improper mounting) if you get full-service installation. Both are limited and have exclusions like weather damage or misuse.

      For DIY projects, customers can pay cash or finance through a third party. They can also pay with a home equity loan or line of credit. Project Solar partners with solar loan lenders to offer two financing options for professional installation:

      • Option A: Loans have higher interest rates but shorter terms. Option A is best if you can pay the loan off quickly, which saves on interest in the long run.
      • Option B: Loans have lower interest rates with longer terms. Option B is ideal for homeowners who want predictable monthly expenses and plan to stay in their current house for at least 20 more years.

      Elevation has an in-house team completes the installation and provides ongoing support if you run into any issues. We like that systems incorporate high-quality solar panels and either Tesla Powerwall or Generac PWRcell batteries.

      The Curb monitoring app is also a positive: It connects to your home's electrical system to give you real-time data about your energy use. The app also lets you remotely turn your smart devices on and off to stop waste and maximize efficiency.

      Happy customers are typically satisfied with the customer service, installation process and pricing. People also like the Curb app for monitoring information about their energy usage.

      “Elevation really made it fairly simple for me to understand and everyone from my sales representative through the support staff were all amazing,” Margaret in Sun City told us. “The biggest plus of course is my electric bill is significantly lower.”

      Another customer, Jayla in Coolidge, liked that the crew showed up on time and was very professional. “They informed me of everything that was being done on my home and walked me through the entire process and answered any questions I had,” Jayla told us. “They did a fantastic job and would definitely recommend.”

      Kayla in Phoenix had a similar experience: “They went above and beyond to make sure any issues or concerns were taken care of.”

      Elevation specializes in solar panel installations on residential properties, particularly with low-profile panels and solar panel roofing tiles. It offers customized quotes and creates a solar energy plan for the system you need.

      The company specializes in low-profile panels and solar panel roofing tiles. Its systems incorporate high-quality solar panels from Panasonic, Q Cells, LG and REC, plus Tesla Powerwall and Generac PWRcell storage batteries.

      • Whole-home energy solutions
      • Solar storage batteries
      • Energy efficiency audits
      • Curb energy monitoring app

      We’ve heard some grumblings about installation delays. For instance, Nick in Phoenix said it took four months to get panels installed and then another year for them to be activated. “Meanwhile I have been getting charged the monthly loan fee since install on top of 100% of my APS bill,” Nick told us.

      Not everyone is upset about Elevation’s timelines. Lindsay in Phoenix appreciated that reps set realistic expectations, explaining upfront that there might be some unforeseen delays (thanks to supply chain issues). “The work might take a little longer, but I feel good KNOWING IT'S done right,” Lindsay told us.

      Unlike our other top picks, Elevation’s contracts are governed by Arizona law, and any disputes that come up are handled in local courts.

      Elevation offers a lifetime workmanship warranty on solar systems and a 10-year workmanship warranty for roof penetrations. Solar equipment, including panels and batteries, comes with individual manufacturer warranties.

      It offers additional product warranties that go beyond the industry standard. This includes the Solar Insure Component Monitoring and Warranty, which covers defects to the system, roof penetration within 3 inches of the solar roof attachment and related labor costs.

      Elevation has financing options through solar loans. This lets you make fixed monthly payments over a period of time. Specific terms and conditions of the loans vary.

      Selected for having one of the highest satisfaction rates for Best Customer Service

      ShopSolar is an awesome place to buy solar equipment for DIY projects. It has a nice selection of equipment, including complete solar packages, fast deliveries and good communication.

      You can find new and used solar panels, solar storage batteries, inverters, charge controllers, cabling and hardware, mounts and racks — everything needed for an off-grid or hybrid setup. It’s great for homes, RVs and outbuildings.

      "The customer service was outstanding," Michael in Tucson told us. "Going with them can save you some time, and it's one of the best shopping experiences I've ever had. They have a very complete and thorough website."

      ShopSolar received praise for efficient shipping and helpful support. Bailey in Waddell tells people that ShopSolar is "a good deal to do if you wanna do things on your own. Everything comes pre-connected and pre-cut. You don't have to make your own wires."

      Another customer, Barbara in Avondale, was amazed by the shipping: "The solar panels were packed [so well] that you could take a sledgehammer to that package and it wouldn't affect the solar panels. They really did a great job."

      Since 2018, ShopSolar has provided solar energy products to over 35,000 customers nationwide. It has various solar solutions, including solar panels, generators, batteries, cables and racks. The online company stocks brands like Panasonic, REC, Renogy, Canadian Solar and EcoFlow, plus it sells custom solar kits. These products are available in full kits containing all you need for self-installation or professional setup. Orders typically arrive within 10 business days.

      • Custom solar kits
      • Price match guarantee
      • 30-day return policy
      • Lifetime customer support

      Some orders might have complications with shipping and delivery. Many packages and equipment are not eligible for free shipping beyond the contiguous United States. For instance, there is a special agreement of terms for customers in Hawaii (and Alaska) who would like to order equipment from Inergy.

      The other important thing to keep in mind is that ShopSolar does not offer professional installation services. So, it’s best to know a little about solar panels and electrical work. Otherwise, you might get frustrated with the process or install something incorrectly.

      Arizona solar panel buyers guide

      Our team has talked to thousands of solar customers across the country — here’s what to expect and what to look out for when buying solar panels in Arizona.

      Key insights

      • In Arizona, a typical 6-kilowatt residential solar panel system is $14,064 before any financial incentives. That price drops to $9,844 after the full federal solar investment tax credit.
      • The federal solar investment tax credit (ITC) is the most significant financial incentive for buying solar panels in Arizona. You can also lease a system with little upfront cost, but you aren't eligible for the ITC.
      • Many solar customers are happy with the service, installation and cost savings. Others felt misled by pushy sales tactics and ended up with monthly bills higher than expected. The state is taking steps to protect solar customers against unscrupulous sales pitches in the residential rooftop solar industry.

      Going solar in Arizona

      Thanks to abundant sunshine, relatively low installation costs and solar-friendly policies, Arizona is a great place for going solar. Panels produce a significant amount of electricity for the typical household. A personal tax exemption and legalized power purchase agreements help make installing rooftop solar systems more affordable.

      » BEST STATES FOR SOLAR: Arizona ranks fourth

      What to look for in a solar installation company

      Solar panels last a long time — you want to hire a well-established company that’s around for system support for at least 25 years. In our experience, the best solar energy companies have a few things in common:

      • A good reputation: Research the company's track record and read reviews. Look out for red flags: Recurring complaints about misleading sales tactics, equipment failures, billing issues and lack of communication are common themes in negative solar company reviews.
      • Local experience: Companies with extensive experience installing solar panels in Arizona are better at navigating regional incentive programs, permit processes, utility policies and designing systems to maximize energy production given the state’s weather patterns.
      • Free consultation: Get multiple quotes from different solar companies to compare prices and services. Be cautious of companies that provide significantly lower quotes than others — this may indicate lower quality.
      • Complete services: The best solar companies provide end-to-end services, from system design and engineering to permitting, installation, inspection, monitoring and maintenance. Also consider if you want a solar storage battery, electric vehicle (EV) charger or critter guard. Critter guards are fencing around the bottom of the solar panel that keeps animals from nesting there.
      • Transparent terms: The contract should be easy to understand. If anything about payment schedules, warranties, monitoring services or system maintenance doesn’t make sense — ask for clarification. Warranties and productivity guarantees provide peace of mind once your system is up and running.
      • Industry credentials: Legitimate solar companies have proper licensing, insurance and NABCEP certification for installers. Bonding is important as it protects the consumer if the contractor fails to complete the job or fails to meet other financial obligations, such as paying for permits or subcontractors. Check the Arizona Contractor Licensing Database to vet potential hires.

      How much do solar panels cost in Arizona?

      Arizona solar panel costs typically range between $8,204 and $23,439. The size of your solar panel system is a big factor in your total cost. It also depends on what incentives you’re eligible for, the condition of your roof and how much sunlight exposure it gets.

      A typical Arizona household needs a system with a capacity of  9.2 kW to offset enough energy costs to make solar viable. Depending on your household energy usage, you might need a smaller or larger system.

      Most installers set the price according to the system's wattage, with a typical cost between $2.50 and $5 per watt. In Arizona, the average cost per watt is $2.44, which is one of the cheapest in the United States.

      Average solar panel installation cost by system size in Arizona

      This doesn’t include the cost of a solar storage battery — which sometimes costs as much as the panels. Solar batteries are a must if you want real energy independence and essential if you go off-grid. Permitting, utility fees and maintenance also add to the cost of going solar.

      How do I pay for solar panel installation?

      Getting solar panels is like buying a car. You could pay cash, but many people finance their system through a solar loan. If you have enough savings to pay upfront, the biggest advantage of paying upfront is you don’t have to worry about interest.

      Leasing solar equipment is an attractive option for people who don’t want to borrow thousands of dollars to go solar or take on the responsibility of maintaining their system.

      Solar panels are designed to last 25-30 years.

      Arizona also legalized power purchase agreements (PPAs), unlike many other states. PPAs work very similarly to leases. The biggest downside to both is that you’ll be disqualified from many of the best financial incentives, like the 30% federal solar tax credit. It also might make your house harder to sell since a new buyer will have to take over the lease agreement.

      » SOLAR PANELS: Lease vs. buy

      What solar incentives are available in Arizona?

      Using the federal solar investment tax credit is the best way to reduce the cost of installing solar panels in Arizona. The ITC gives you a credit worth 30% of the total cost of your solar power system, including labor and permit fees. The credit is nonrefundable, though, so any unused portion rolls into future tax years.

      The ITC is not a rebate or a refund.

      In addition to the ITC, Arizona has multiple statewide and local solar incentives, including an income tax credit for 25% of the cost of buying solar energy equipment (the credit caps at $1,000). You also receive a 100% sales tax exemption with no maximum limit when purchasing or installing solar panels, solar water heaters, wind generators and similar equipment.

      » MUST-KNOW: Tax deductions for homeowners

      Are solar panels worth it in Arizona?

      For many homeowners, going solar is worth it in Arizona for the reduction in energy bills and reliance on local power companies. Over 25 years, Arizona homeowners with solar panels can save about $59,661 in total utility power costs. A typical residential solar panel installation usually pays for itself within 7 years in Arizona.

      Over 25 years, homeowners with solar panels can typically avoid $20,000 to $90,000 in total energy costs.

      One solar customer we talked to, Lorene in Tucson, went solar for a number of reasons: "Sustainability, to save money, to get out from under the thumb of TEP." She likes leasing the system and plans to rely on it in retirement. It's nice having a locked-in, predictably low monthly energy bill.

      Similarly, Chad in Peoria is also saving a lot of money each month and really likes “not having to pay anything else to APS.”

      Arizona's climate makes it a great location for residents interested in going solar. The state averages seven to eight peak sunlight hours per day, maximizing the amount of power produced by your solar energy system. Ultimately, going solar is a worthwhile investment in most states, but particularly in Arizona.

      » STILL NOT SURE? Solar energy pros and cons


      How do I know if my house is a good candidate for solar?

      Ideal candidates have a south-facing roof with little to no shade and are in areas with high solar irradiation. It's also essential to assess the structural condition of your roof to ensure it can support the weight of solar panels.

      NREL’s PVWatts Calculator estimates how much electricity a solar panel can produce over a year on your house — just type in your address. You can also use Project Sunroof, a free solar savings estimator powered by Google Earth imagery.

      Do I need a permit to install residential solar panels in Arizona?

      The permitting process depends on where you live. For example, Maricopa County solar permits can be found online. If you live in Phoenix, use the SolarAPP+ Program​ to verify code compliance for residential solar panel projects.

      Is my HOA allowed to restrict solar panels?

      No. Homeowners associations in Arizona are not permitted to unreasonably restrict solar energy systems.

      How does net metering work in Arizona?

      If your solar panels generate more electricity than your home needs, the excess can be sent into the grid through net metering. You get a credit on your account when this happens. During times when the solar panels don't produce enough electricity, you can use those credits to draw electricity from the grid.

      In 2016, the Arizona Corporation Commission (ACC) voted to replace net metering with net billing for new solar customers. This means you’ll earn less for the surplus power they send back to the grid compared to traditional net metering policies in other states.

      While often categorized similarly to net metering, Arizona's net billing policy does not technically meet the definition, as excess solar generation is no longer credited one-to-one against household electricity consumption for that billing period. Unless you install a battery to store excess energy your system produces during the day, you should enroll in net metering if possible.

      What is the difference between a solar lease and PPA?

      If you lease a solar system or enter a PPA, you don't own the panels, but you benefit from the cheap electricity they produce. The solar company that owns the system is responsible for maintaining it, so you don't have to worry about ongoing maintenance costs. The key difference is how you pay.

      • Lease: Entering a solar lease is basically renting a solar panel system. As with leasing a car, you pay a fixed amount every month over a set period of time, typically 25 years.
      • Power purchase agreement: With a PPA, you don't pay a fixed monthly price. You pay for the electricity the panels produce, usually at a lower rate than you would receive without a PPA.
      Can I get free solar panels in Arizona?

      There's no legitimate, totally free option to get solar panels in Arizona that we're aware of. Unfortunately, scams that promise free solar panels can cost consumers a lot of money. There are no programs that provide solar panels in Arizona, but you can lease or enter a power purchase agreement with no upfront cost (or a small one).

      » FREE SOLAR PANELS: Are they really free?

      Is it cheaper if I install solar panels myself?

      Installing solar panels yourself might initially seem cheaper due to saving on professional installation costs. However, it's crucial to consider several factors before deciding on a DIY approach. These include the complexity of the installation process, the need for proper safety measures, obtaining necessary permits, ensuring the system meets electrical codes, the impact on warranties and the potential for mistakes that could affect system efficiency or your home's safety.

      The cost of hiring professionals to install your solar system varies depending on the size and complexity of the project. The price you pay for your solar panels also depends on a range of factors, including the size of your system and the quality of your panels.

      Do I really need a solar battery?

      Investing in a solar battery system makes sense, especially if net billing rates decline in Arizona. It lets you maximize the power your system produces by storing excess solar energy instead of sending it to the grid. This reduces reliance on the grid and can save money if net metering rates are low.

      Batteries also stabilize energy costs by avoiding expensive peak electricity rates, providing backup power during outages, and increasing solar utilization by preventing excess energy from going to waste.

      How many solar companies are in Arizona?

      As of publishing, there are 364 solar companies in Arizona (78 manufacturers, 166 installers or developers and 120 others), according to the Solar Energy Industries Association (SEIA).

      What is the difference between a solar installer and a solar broker?

      A broker can be helpful if you value convenience. If you want more control and potentially lower costs, it's best to work directly with a solar installer.

      • Broker: A solar broker is a middleman or intermediary who helps connect homeowners with solar installation companies. It typically has relationships with various installers and can help you compare options. Often, people selling solar panels door-to-door work for solar brokers.
      • Installer: A solar installer specializes in the design, procurement and installation of solar panels and related components. It typically has its own team of trained technicians who handle the installation process.
