Harmon Solar, located in Phoenix, Arizona, is a mid-sized company that specializes in designing and installing solar systems. Founded in 2008, it services residential and commercial properties.



Specific Types of Solar Offered

Harmon Solar uses industry-leading products from Fronius, Enphase, Hyundai, Tesla and SMA to provide its customers with superior services. These include:


Residential solar systems: In installing solar systems for homes, Harmon uses a design process that can be adjusted based on the data collected from completed projects. 


Commercial solar systems: Harmon Solar can help businesses of all sizes and types save money on their energy bills by installing solar panels on their properties.



Installation Costs and Processes 

Harmon Solar provides customers with a quote for the price of their solar system, which is free and without obligation. If the customer accepts the quote, Harmon Solar will design, procure permits and equipment, and install the system. The installation process usually takes no more than 90 days and includes city inspection and approval.



The cost of going solar varies from customer to customer, depending on the size and type of system needed. The company does not disclose how much each solar panel costs but claims the prices are affordable. Customers who can’t afford to purchase the panels outright can lease them from one of Harmon’s partners and pay $0 down. Many clients say that they have had a positive experience with Harmon Solar, so it appears their investments are paying off.



Harmon Solar meets some criteria that help to substantiate its legitimacy. Here are the following accreditations and proofs:
