EnergySage

EnergySage is a Boston-based online marketplace, not a hands-on installer, that connects homeowners with pre-screened, certified installers for solar, home batteries, heat pumps, and EV charging so they can compare quotes side by side. The company is listed as a member of the Boston Chamber of Commerce and carries an A rating and BBB accreditation. On volume, the record is strong: Google shows a 4.8-star average across more than 1,030 ratings, and a March 2026 reviewer described getting help from EnergySage and its associated contractors as low-pressure and pleasant. That matches what most people use the service for, a fast way to gather several bids without being cold-called by installers directly. Where it gets more complicated is what happens after a homeowner picks an installer through the platform. Reviews describe cases where the referred installer stopped responding, left a system non-producing for months, or in one case placed a lien on a customer's home, with the reviewer saying EnergySage did not step in once a contract was signed. A similar account naming the same installer appears in an older, independent review too, suggesting it isn't a one-off. The three most recent reviews on file, from February and March 2026, are all negative, and one questions whether the added cost EnergySage builds into installer pricing is worth it. The BBB lists 3 complaints against the business itself. Worth confirming before using the service: EnergySage's own accountability appears to end largely at the referral, so ask any installer it connects you with directly about warranty terms, response commitments, and recourse if the work stalls, since that is where the reviews suggest things can go wrong. For comparison-shopping quotes with low sales pressure, the marketplace has a long, mostly positive track record; for confidence that a chosen installer will follow through, the evidence here says to do your own diligence on that specific company.
