This rooftop project for H.T. Berry put the Massachusetts-based company on track to be the region’s first and only net-zero carbon emissions supplier of paper, disposable, and janitorial products. This is an important differentiator for the company, helping it and its subscribers achieve their sustainability goals. Consisting of over 1,100 panels, the system produces about 300,000 kilowatts of clean electricity annually. The system generates energy savings while making productive use of the company’s otherwise unused rooftop area.
