603 Solar - Exeter, New Hampshire

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.

We had Joey from 603 Solar come out in Oct to go over the details and give us a quote. Their pricing was competive in comparison with other solar installers plus I liked the fact that they were locally based. In Jan their installer Grateful Electric came out to complete the installation. They were professional and did a great job. We went online Jan 15 and since Feb the panels have been producing at least 1MW or more of electrical output. The last electric bill that I had was in March and it was only about $13. As of right now I actually have a credit on my electric bill. Joey and the rest of the 603 Solar team did a great job from start to finish. If you are looking for a turnkey Solar installer that will take care of everything from start to finish, you should definitely take a look at 603 Solar.

Like all of the reviews I have read, 603 Solar and Grateful Electric did an excellent job throughout the process, from planning to installation, to activation. I'm totally happy with the end-product. I'm doing laundry right now 100% on solar power.

I had been researching different solar options for several years and decided to hire 603 Solar for the system design and installation at our house in Madison, NH. Steve came out to the house and conducted a very detailed site survey and fully discussed how the system would be installed and what to expect as far as power production. Steve is very knowledgeable and easy to work with. I decided to proceed with 603 Solar and our project was very complex as it involved installing the solar panels on a stand-alone barn roof, installing underground electrical conduit for the power cabling run to the main house panel, etc. I also had the barn roof replaced prior to installing the panels as the roof was 15 years old and I did not want to put panels on an aging roof. I hired a roofing contractor who was able to get the work done well in advance of the solar installation, so everything worked out. Steve and I coordinated the different contractors and site prep work, and everything went off without a hitch. Steve and I also discussed future expansion of the system and the 603 Solar electrician installed heavier gauge power cables to support any future expansion. This will make adding additional panels much easier when the time comes. 603 Solar also handled the town electrical permit application and coordinated with Eversource to connect our system to their grid. The system has been up and running for 10 days or so now and the power production is exceeding my expectations. The system is producing 50+ kw-hrs a day even with light clouds in the sky. Production drops on rainy days but this to be expected. Overall, 603 Solar was great to work with and I highly recommended them. A+ on our project.

I highly recommend 603 Solar to anyone considering investing in residential solar generation. I requested and received quotes from 4 companies and 603 Solar was the most responsive to my questions about feasibility, technology options and cost. We installed 28 panels which were installed over two days. They could have been installed in one day, but the crew opted to stop during the first day in order to prevent damage to my newly installed shingles due to excessive temperatures. The installed panels, and connections look fantastic – installed with pride of craftmanship. The permitting, inspection and interface with City and Utility were seamlessly handled by 603 Solar. Our net meter was installed, and we were generating within 3 days of the panel installation. 603 Solar’s attention to us did not end at the final installation – their guidance on obtaining tax credit and also sale of REC’s has been extremely helpful. We are very happy to have chosen 603 Solar for this project.

From our very first interface with Steve, we were impressed with his friendly, courteous, and informative assistance. His presentation of the financial details and graphics was impressive. In later dealings, the office staff and workforce were superb. All questions were answered. All phone calls/emails were returned promptly. 603 handled all the paperwork and permits. The project actually finished many weeks before the original planned date. We now look forward to receiving our electric bill to actually see how much we are saving. We're thankful a neighbor recommended them, and that we took the leap to solar with 603.

Fantastic experience from initial meeting to turning the solar system on. 603 Solar made what we thought was a complicated process extremely simple. Shout out especially to Steve Cavallaro, our consultant, who was always available to explain the process and technical details of the system itself and the process from design, inspections, installation, and turning the system on. Steve explained the process to us and, as it turned out, that's exactly how the process went. His time estimates were spot on, even for things such as Power Co. and Town inspections that were out of 603's control. Very impressed with the company especially since they are local to Southern NH.

Dealing with 603 Solar was a pleasure from start to finish as we replaced an old PV system with a new, upgraded one that will cover all of our electricity usage, including heat, hot water, and an electric car. Their service was outstanding at every step of the process. My work as an energy consultant keeps me fairly well-informed on renewable energy systems, net metering, etc. Steve Cavallero eagerly and honestly answered all the technical questions I threw his way. I highly recommend this company!
