The Good

  • NABCEP Certified
  • Enphase Premium Installer

NABCEP Certified

1Solar has been been certified by the North American Board of Certified Energy Practitioners, or the NABCEP. The NABCEP authors industry-leading certification programs for solar technicians that promote best standards and solar installation practices. An endorsement from the NABCEP signifies both that 1Solar has undergone advanced training and that homeowners will receive a quality, expert-installed solar PV system.

Enphase Premium Installer

1Solar is also an Enphase Premium Installer. Enphase is one of the industry leaders in solar inverter technology, which allows solar panel systems to covert solar energy at an efficient rate as well as monitor the performance of individual solar panels. With these tools, homeowners can easily monitor both their energy consumption and the output of their solar panel system to ensure optimal performance and energy bill savings.


The Bad

  • Limited Availability
  • Undisclosed Warranty
  • Undisclosed Financing Options

Limited Availability

As stated above, 1Solar is only available to residents in Utah. While a local focus is becoming increasingly common in the solar industry, local companies like 1Solar may find themselves at a disadvantage compared to larger companies with a more national presence and greater brand recognition. Promoting verified One Solar reviews could be an effective way for the company to highlight its customer interactions and distinguish itself in a crowded and competitive Utah solar market.

Undisclosed Warranty

While the company's equipment warranties come directly from the manufacturer (25 years for Enphase inverters; 12 years for VSun solar panels), 1Solar's own workmanship warranty is nowhere to be found on the company website. The workmanship warranty protects the solar energy system against installation errors. Leading solar companies attach a service warranty good for the lifetime of the system or 25 years.

Undisclosed Financing Options

Although 1Solar often describes the benefits of solar array ownership, as opposed to leasing electricity from the utility company, the company makes no explicit mention of its available financing options. Solar panel installation ownership can only be secured through direct purchase or solar loan. Additional financing options like solar leases and power purchase agreements (PPAs) are not mentioned either; though 1Solar in all likelihood will discuss available options with customers after the initial consultation.


The Bottom Line

1Solar has a proven track record of expertise and quality solar installations across the state of Utah. The company installs top-level equipment and has been certified by the NABCEP. Utah customers are encouraged to look into what 1Solar can do for them — and then compare the company's workmanship warranty and available financing options against other, leading solar providers in their area.

Bella Houtz South Jordan, UT

We purchased our solar panels through One Solar. We felt like they were very proficient and did a quality job for us. We felt like in shopping for the product they were a little more expensive but the quality was better than other companies we considered.

This contractor that came to my house answered all my questions honestly. He was very knowledgeable of all the steps of the solar process. The customer service was also great and kept us in the loop with every step along the process. Great company and I would recommend them to anyone.
