How We Calculated Our Top Solar Installers Lists

When we created our top solar installers list, we wanted to ensure that we were thorough and fair in our analysis. We did extensive Google searching to find our candidate pool. For each location, we started with around 100 companies to compare. Then, individually researched the companies to get an in-depth analysis of how they compare to each other.

For each installer, we looked at the following factors:

  • Reviews
  • Do They Have NABCEP Accreditation?
  • Do They Have BBB Accreditation?
  • How Do Their Warranties Look?
  • Do They Offer Financing Options?
  • Do They Offer Product Options?
  • How Long Have They Been in Business?
  • How Many Customers Have They Serviced?
  • How Many Employees Do They Have?
  • How is Their Employee Satisfaction?

Reviews carried the heaviest weight for us because nothing speaks more to a business’s worth than actual customer experience. We compiled reviews from many sources, including Energy Sage, Solar Reviews,  Google, Yelp, Consumer Affairs, Best Company, Facebook, BBB, and HomeAdvisor. To come up with our review score, we averaged the cumulative review scores from all of the sites.

We removed any company that didn’t specifically focus on residential solar panel installation. Then, we removed people who had subpar warranties or lacked accreditation. We also eliminated companies who didn’t have enough reviews online to give us a real picture of their customer service. Companies that had limited information available online, including a hard to navigate or non-existent website were also removed. Financing and product options were also required to make our top list. In addition, we took employee satisfaction into account.

Once we removed the installers that didn’t fit our requirements, the installers with the highest overall review scores made our top ten.
