Why Marlborough homeowners are going solar.
Marlborough is a dynamic city with a thriving technology sector and diverse residential neighborhoods. Its location along I-495 and the Massachusetts Turnpike makes it a center for business and innovation, and a standout market for commercial solar.
Marlborough offers exceptional opportunities for both residential and commercial solar installation. The city's residential neighborhoods feature a wide variety of home styles, from the established neighborhoods near downtown to newer developments in the western part of the city. Marlborough's significant commercial and industrial base, particularly along I-495 and Route 20, includes numerous facilities with large, flat rooftops ideal for commercial solar. As a city with its own municipal government, Marlborough's permitting process is straightforward, and our team has established strong relationships with the building department. Several of our most successful commercial installations have been in Marlborough, helping businesses take advantage of the strong financial returns that commercial solar offers in Massachusetts.
