LAST UPDATED: March 1st, 2022

Headquartered in Phoenix, Arizona, Harmon Solar is a local, family-owned company that has been in business for over 40 years. Originally founded as Harmon Electric, Inc. by Richard and Jean Harmon in 1975, the company began offering solar services in 2008 under the name Harmon Solar. Harmon Solar proudly offers customized solar systems and personalized service in Arizona. The company uses a licensed roofing contractor and structural engineer for each of its solar installations.

Harmon Solar believes in taking the extra steps necessary to ensure that each job has been completed to the absolute highest of standards. As a result, every home has a full structural analysis conducted prior to installation and stamped by a structural engineer. The company also has roofing crews installing the stand-offs prior to the installation team, and if the roof needs maintenance before the installation, Harmon Solar can roll it into the deal since it has its own roofers. Additionally, the company has NABCEP certified solar professionals to ensure that every project is done properly.

Top Ranked Companies


The Good

  • Equipment
  • Full-Service Provider
  • Multiple Financing Options


Harmon Solar only uses top-of-the-line PV solar panels and equipment. Additionally, the company uses a licensed roofing contractor and structural engineer on every single project to ensure that installations are completed to the highest of standards. Harmon's professional, NABCEP certified installers have years of experience, backed up by Harmon Solar's satisfaction guarantee.

Not only does the company install quality solar energy systems, Harmon Solar is also qualified to install solar battery storage solutions, including the Tesla Powerwall and the latest batteries from Sonnen. Solar batteries make a great addition to any existing solar system because they improve solar savings on monthly electric bill.

Full-Service Provider

Harmon Solar is a one-stop solar shop.  The company will oversee your entire project, from customized design to installation to submitting paperwork for permits.  Their structural engineers will assess your location and complete the appropriate analyzes and obtain the necessary building permits. Harmon Solar also takes it to the next level by analyzing data from existing projects and applying best practices to its accounts for radiance, weather patterns, local climate, shading, pollutants, and other potential factors that could impact your system's energy production.

Multiple Financing Options

One of the benefits of going with Harmon Solar is the range of financing options the solar company has made available for the homeowner. In addition to direct purchase and solar loans — both of which qualify solar panel owners for the Federal Solar Tax Credit — Harmon Solar also allows customers to rent the solar panel system through a solar lease, which requires no money down and covers all the maintenance and installation costs.


The Bad

  • Availability
  • Lack of Transparency


Currently, Harmon Solar only offers its solar services in Arizona. While being a local company does have its advantages, only residents of the Grand Canyon State have the ability to do business with Harmon. If you don't live in Arizona, you'll need to find a different solar company.

Lack of Transparency

Unfortunately, Harmon Solar's website leaves out a lot of important information. For example, does the company offer online monitoring? What about moving options? What are the contract details? These questions are all left unanswered by Harmon's website, which can be frustrating for potential customers who are trying to decide whether or not Harmon Solar is the right company for them.


The Bottom Line

Harmon offers multiple payment options, top-of-the-line equipment, and quality installations. While some company details are unclear, readers are encouraged to investigate our verified Harmon Solar reviews to see how the company does business and treats customers. If you live in Arizona, Harmon Solar might be a good option for you. If not, you'll have better luck with a different solar company.

Dale A Branson Phoenix, AZ

Harmon's HQ is 3 hours from my residence. The sales man was here right away when asked for information and quotes. I picked Harmon because of their long history of service in the State of Arizona. Not being in more than one state is not detrimental. I did not use any other company, because I was informed that because this residence is owned by a church, it is considered commercial. The other companies were residential only. Harmon's service was top notch. I was in touch via phone and email with the project manager. The installers, engineers and elctricians were very pleasant to deal with. The materials came when I was told. The HOA wanted all conduits and new boxes on the outside wall painted to match, Harmon had no problem with that. The panels are larger and more productive than some of the other companies. Harmon informed me that they only like to mount the panels so they would not be seen from the street. This happened. Most of my neighbors still wonder when I am going to solar. The power produced is amazing, more than I expected. I would gladly recommend Harmon to anyone who asked me. With the change in product technology, the warranty period is good enough.
