Certifications aren't necessarily required, but are a great way to weed out lower quality installers. Having the proper licenses and insurance policies is the bare minimum requirement for solar installers. But different states require different policies for solar installers. It can be difficult to keep track on your own, which is why we ensure our installers meet all qualifications in the areas they serve. At EnergySage, we verify that all installers have at least two to three years of legitimate experience designing and installing solar panel systems before we let them join our Marketplace. We also confirm they have multiple successful installations under their belt.
