The company was faced with rising electricity costs, even through the municipal utility in the town of Raynham. 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 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.


30% reduction of electricity costs

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