603 Solar – Solar Installation in Exeter

603 Solar did an amazing job installing a solar array on my garage roof and backside of my business this past month. From start to finish the project went smoothly, with clear and regular communication from Sean and timely, and clean electrical work and install. The panels look great (they blend in quite well with the roof) and are working exactly as expected. If you’re in the market for solar this is absolutely the company to work with!

603 was absolutely wonderful to work with for the solar install! From the estimate right on through the project, they had great communication, they did clean work, and made sure it was hassle free. I would not hesitate to work with them again and again.

Quite simply the BEST contractor I've ever worked with. Communication, Service, Installation and follow-up are impeccable! Will 100% do business with them anytime I need solar work done. We were undertaking a fairly large project that included two key components: Mini Splits (heat pumps) and Solar. So, we had two great examples on opposite extremes. Luckily for us, 603 Solar made their portion of this project a breeze. From the very beginning, they communicated about the schedules, where things stood (ex. awaiting the Town Permit), when we could expect delivery of the equipment and more. They then went on to provide the most competent installation team ever (Tyler and Caleb were outstanding). Such professionalism on every aspect of the install. Day 1 they had all the racking done for our 48 panel system, all the electrical boxes put in. Day 2 they finished the panel installation and running all of the wires. By Day 3, they just had to come out for a few minutes to liven up the system. Photos speak for themselves. Everything neat, tidy, labeled and organized. Sean and Tyler kept in constant contact with what to expect next from the utility, the inspectors (because, yes, they pulled permits ... Inspector even said "we never have to worry about their work; it's always done perfectly"). Sean also came out to take a close look at the work, make sure we knew how the system operates and how to use the app. Marian even followed up with more ways to save by selling our RECs (Renewable Energy Credits). Every single one of their team was fantastic.
