"Granite State Solar was great to work with. They helped us along with the whole process. We were thinking about going with a generator for backup power, They helped us explore solar with Batteries. Not only do we not now have to listen to a generator once a week, but we also get to make power whenever the sun is shining. The batteries allow us to have 1/2 a normal day power amount on demand during storms and allow us to use our own power most nights. Granite State came in and after 3 days on-site had the whole system installed and waiting on the new meter. They also helped us understand how the snow would slide from the panels, keeping us safe and making power. I would use them again for any system additions or recommend them to a friend."

"I selected GSS based on their reviews and because they are local to my community. The entire process was outstanding from our initial meeting to the final install of our panels. Eric patiently answered all my questions along the way and just I had read in other reviews, the entire team from administrative support to installers proved to be very professional and a pleasure to work with. I very highly recommend GSS for your solar needs and will be looking to them for expansion and a possible battery backup in the future."


"I always like dealing with local companies, and Granite State Solar really delivered. They installed a 28-panel system on my house in August 2017, and now, in May 2021, I can say that the installation has been exceptional.

I do not believe I have had to make a single follow-up call for service etc. I have also not paid one dime in electricity costs since the day the system went live. I also get the REC checks quarterly for my excess power purchased from me by the power company.

GSS was knowledgeable, prompt, and competitive. I compared two or three suppliers as it was a major investment, and I am so happy I chose GSS as they impressed me from the start. I was eager to add solar to my home, but I was very much an amateur and I needed competent assistance in choosing my project. I would recommend GSS to anyone, and you should get great service, quality components, and excellent support.
It is great to deal with a successful NH company!"


"We decided to go solar in May of 2018 after two years of research into other companies. This was our first experience with solar so naturally, we were nervous about taking the leap. We worked with Eric to size the system to get what would work best for us. We had many questions as you can imagine. It took many meetings back and forth and a number of phone calls. All of which resulted in additional information about going solar and what the expectations were. Eric was extremely knowledgeable, patient and transparent throughout the process. He even went as far as compiling a quote with analysis of multiple systems to meet our budget and family needs. The communication was great as well. Once we signed the contract everything came together exactly as planned. The installers were professional and were cognizant of the system aesthetic inside and out. The system works flawlessly and is producing more than originally anticipated! It's rare this day and age to have a company as well-rounded as GSS. It was a pleasure doing business with Eric and the GSS team. Thank you for helping us achieve out goal. This company is excellent and I would and do highly recommend them to anyone thinking of going solar!"
