Project Description

Mastria Auto Group

Mastria Auto Group is a family-owned dealership in Taunton, MA, representing the Buick GMC Cadillac, Nissan, Subaru and Mazda brands. The company has been in business for more than 60 years.


The company was faced with rising electricity costs, even through the municipal utility in the town of Ranyham. It had installed LED lighting and high-performance garage doors to reduce costs. At the same time, Mastria realized it had a valuable asset in its roofs, and wanted to explore its options.


Mastria Auto Group partnered with Solect Energy Development to install systems at its Buick GMC Cadillac, Nissan and Subaru dealerships. A fourth dealership—Mazda—needed improvements to its roof, so Mastria deferred the project until mid-2015.


The systems are expected to cover up to 30 percent of the auto group’s electricity costs annually, saving the company up to $40,000 each year. When the Mazda dealership is completed, the company will save an additional $10,000 per year in electricity costs. In addition, Mastria will generate significant additional revenue annually through the SREC program.
