When Boston Solar was founded in 2011, the goal was clear: bring honest, high-quality solar installation to Massachusetts homeowners who deserved better than the aggressive sales tactics and broken promises that were clouding the industry. Founded by Daniel Mello Guimaraes, the Woburn-based solar installer has spent more than a decade proving that local matters. Since that first installation, Boston Solar has grown into the state’s leading Massachusetts-based residential solar contractor, completing over 6,000 installations and installing more than 30 megawatts of clean energy across New England. The company operates as a fully vertically integrated installer, meaning every solar consultant, system designer, electrician, and installer is an in-house employee—no subcontractors. This approach gives Boston Solar complete control over quality, communication, and customer experience from the first consultation through decades of system performance. The team has earned recognition year after year, including being named a Top Solar Contractor by Solar Power World for five consecutive years and earning the 2020 Guildmaster Award from GuildQuality for exceptional customer service. Massachusetts homeowners have responded with over 500 Google reviews averaging 4.9 stars. Boston Solar offers residential and commercial solar installation throughout Massachusetts, along with battery storage systems and EV chargers. The company has expanded into high-profile commercial projects, including a 297-panel solar array for the MGM Music Hall at Fenway, and serves as a Proud Partner of the Boston Red Sox. Whether it’s a single-family home in Worcester or a concert venue in Boston, every project receives the same attention to engineering precision and customer care. For homeowners considering solar panels in Woburn and across the Bay State, Boston Solar represents what happens when a local company commits to doing solar energy the right way—with transparency, expertise, and a genuine investment in the communities they serve.
