603 Solar

We worked with 603 Solar, who was referred to us by another customer of theirs. Sean was incredible throughout the process! He responded quickly, always gave us all the information we needed, and worked really well with Eversource to get us up-and-running. Our Eversource application was approved in less than a week, and they got Eversource to our house 2 business days after the installation. If you're converting to solar (which is a no-brainer), you've gotta go with 603 Solar!

Our dealings with the crew from 603 as well as their installers from Grateful electric was seamless. Every phone call and text was responded to quickly. From planning to installation to activation there were no issues, any questions quickly and professionally answered. 603 and Grateful handled everything necessary to complete the process. It was very comforting and reassuring process start to finish!! Very pleased with the experience!!

603 Solar was wonderful to work with. Sean was patient and flexible, designing a system that fit our needs. His crew worked with us to minimize the visual impact of the array and wiring. They are knowledgeable and professional. We were very satisfied with the outcome.

From first introductions to completed project everyone we interacted with were professional, answered all our questions and delivered as promised. The installers, Grateful Electric were particularly outstanding. We are extremely pleased we went with this group.

603 Solar installed our solar array last fall and it is really paying off!  This month (March) the electric company owes us money so our bill said "No Payment Due" !!!  I love it!  Highly recommend - they were also way less expensive than the other solar companies that we had estimates from.
