603 Solar

I was very happy with the service I received with 603 Solar. Every response was clear, efficient and informative. The prep, installation and post installation approval process went smoothly and quickly. Thank you, The Sanders family

Our system was installed on schedule and finished up quickly. Steve C. was great and helped us through the proposal, permit and installation process. The office folks have been great about answering questions and getting us set up for success. The 603Solar Team is great. Thanks for a really positive experience!!!

After many years we decided to install solar for our electrical needs. After evaluating local vendors we selected “603Solar.” The communication was excellent, the process was systematic and efficient with clear congruent communication between all tasks . The result was a very high quality installation completed and operating ahead of schedule. This is a state of the art company that understands the value of quality and customer satisfaction. We highly recommend 603Solar. Steve Hollis, NH

We can't say enough about the work of 603 Solar and the way they partnered in every aspect of the process for our home in Durham, NH. Zach called right away after our initial inquiry and within days we were in process to have panels installed on our barn. Zach and Sean communicated well at every turn, and they worked with the local inspectors and even with Eversource to arrange a transformer upgrade on the pole that services out house. Installation happened in the blink of an eye, and they even recommended a great electrician (Grover Electric) to do some additional work at our house. We've been up and running for about six weeks now and we appreciate the many ways 603 Solar made it happen.

Jeff Cantara and 603 installed Enphase inverters and Q Cell 425 watt panels for me. Excellent, painless, reasonable price. John

603 Solar has been great. Our "salesman" Jeff was very informative and honest. He actually talked us out of spending additional money on "add-ons" that a previous solar company pushed us to do. Jeff also made several revisions to our design at our request so we could get things "just right". 603 kept us informed throughout the entire process, their installers showed up when they said they would and didn't leave any mess/debris behind when they were finished. The entire process from our initial meeting with Jeff to when we were able to "turn on" our new net meter took less than 2 months.. and part of that time was waiting for permits and the utility company.
