Fantastic experience! I interviewed four companies in the summer of 2025. The goal: to install a 10 panel solar array on my garage before Jan 2026, to chase expiring tax credits. Two companies dropped the ball (Tesla & 603). Granite State Solar and one other (All Energy Solar) were on point, but GSS went above & beyond with an initial on-site inspection with drone map, & followed up THAT NIGHT with a detailed proposal / projected solar production based on the drone map, in-line w/my budget—all before I had to pay for or sign anything. GSS also seemed to have specific local knowledge the other's didn't (I’m in Thornton, NH). It was a no brainer to pull the trigger w/them. After that, they outlined a schedule to get permits, deliver the panels, do the install, & work with my electric company (NHEC) to finalize the details (meter, credits, etc). It went like clockwork. Every employee I interacted with at Granite State Solar was on-point. Knowledgeable, patient, friendly, quick to reply, and—especially Ashlee—bulldogs on my behalf with NHEC when they delayed things, or threw up red tape. GSS partners with third party contractors for small jobs like mine when they’re super busy, but the third party crew (Roger & Mike) were amazing. Quick, super friendly, quality work, & they rolled with the punches. There was a modification needed, due to some unexpected roof structures—that is to say, something went wrong. Roger worked with me & Ashley & the fix was sorted & the panel layout modified in three hours with no extra cost to me. It’s one thing when everything goes right, that’s great. But, when something goes wrong & everyone reacts professionally w/no drama, that’s a more valuable data point for me & gives me confidence in GSS going forward / long-term. Eric took over at the end & did a fantastic job clearing up any last questions I had abt how to use the Enphase monitoring software & what I should expect over the first year & first five years. One of the best customer experiences of my life. Love my solar panels!
