VERY satisfied customer of Solar-Powerwall-SPAN panel installation by Maine Solar Solutions. From first contact to installation to final configuration, and all steps in-between (including financing), this company was top-notch! Its amazing to think that one day one after installation, I started getting paid by the sun. I cannot understate the quality and functionality of the tech, particularly the SPAN smart load panel, the Tesla Gateway and Tesla Powerwalls, which all provide seemless and undetectable power backup to my home. Were it not for my Tesla and SPAN apps, I would never have known about the 2 short power-outages we had in Topsham recently. Complete peace-of-mind for Maines weather patterns bringing power interruptions going forward. Special shout-out to my installation teams: SPAN/Tesla Gateway (total tear-out of old legacy load panel and rewire-install of new tech) by Adrian and Trenor; and solar install crew FIVE, Mike, Jared, Jacob, Jonas, Reuben and Noah. FABULOUS WORK! Highly recommended!!!
