About Cotuit Solar’s Philosophy, Founder, Team and Experience.


Our Philosophy

Cotuit Solar is passionate about bringing renewable energy to as many people as possible in order to conserve local resources and reduce our carbon footprint. We are proud to install solar on Cape Cod, Martha’s Vineyard, & Nantucket go solar! We believe that small actions by many people are the means to a sustainable future. The Cotuit Solar team is a group of conscientious people who try to live in a sustainable way.

As a small independent business, we value local products and try to limit our impact on the planet, therefore, most of us have Photovoltaic Solar arrays or Solar Thermal systems on our own homes -not to mention vegetable gardens, composting toilets, and drive fuel efficient cars.
