    We had a great experience with Cotuit Solar. It started with the sales and went through to live date and beyond. The sales person was the most knowledgeable sales person we met out of all of the companies we talked to - which gave us confidence in the company. The install crew was AWESOME!! They were respectful and kept a clean job site. After going live we had a couple of questions and the office crew was super responsive- even after we had paid. This is a company from beginning to end that is committed to helping people go solar.

    The men and women of Cotuit Solar were just what I had wanted, and expected. They were personable in the office, on the phone, and on site. The men who came on two separate days were well organized and efficient. They worked well together. I was happy to provide lunch for them, as we are quite a distance from any warm place to eat. As a retired Navy man, I know the importance of taking care of the crew. Sure, they might have been ok with their own subsistence, but we all felt better after hot soup and pizza!
    I would encourage anyone who has to choose, to go with Cotuit Solar.
