After meeting with multiple solar companies, we chose Granite State Solar to install our 20 panel ground mount system and are still happy with that decision! From the start, they provided personalized and professional service. They were thorough and valued our time keeping the process streamlined and easy for us. The install process itself was only about 6 hours from start to finish even with trenching and all the electrical work. We’ve had our solar panels for about 6 months now and haven’t paid an electric bill since. We could be happier with our experience and recommend GSS for anyone looking to solar.

Excellent service from start to finish!! Granite State Solar (GSS) installed a second solar array for me and recently added a Tesla Power Wall.

I did my research and made the decision to use GSS based on past work performance and the value they added to my homes.

From scoping out the job to installation, I could not have been happier with the quality of work I received and the communication each step of the way. I recommend GSS to help you explore adding Solar to your home!!

The system has been up and running for a year, providing more stability for our home. GSS has answered all questions and has provided great support all along. Tim, Ashlee, Raenor and Ben have been excellent!

We had a great experience with Granite State Solar when they installed our system in 2024. Andy, who led the team that designed the system, did a great job communicating and answering questions, and was very accommodating in figuring out a way to tailor the system’s design to our needs and preferences. The installation itself happened ahead of schedule and was quick and efficient. We had a few technical glitches with the equipment but the team was responsive and got them taken care of within 24 hours. Our system has been working great and I have recommended that friends and family reach out to Granite State Solar when they’ve expressed interest in rooftop solar on their homes. It’s a pleasure to do business with such a great local company!

Granite State Solar worked out great for us. Super work crews got everything done quickly and efficiently. Just got first electric bill after 2 weeks live with system. Bill dropped $60. Anticipate no bill for this month. The salesman, Andrew, even came out and showed me all the nuances of the Tesla app. The lady who mans the phones at the office is really nice and always gets back to you.
Would recommend Granite State Solar to anyone looking for a complete system.

A difficult project, wetland and zoning considerations, but Granite State worked with me, answering questions and providing suggestions along the way. Very accommodating on my unavoidable delays, rescheduling the project timeline for me multiple times. I am sure the delays were a headache for the project management and installation team -- who were great -- and working quickly with minimum disruption to the property. Great experience, highly recommend Granite State!

We would highly recommend Granite State Solar. First of all, their bid was extremely competitive. But what sold us on Granite State Solar was their service and the time that they spent answering our questions and helping us plan the entire project. They were terrific! They did what they said that they would do every step of the way. Once we get the metal portion of our roof resolved, we will be bringing Granite State back to our house to add more capacity. Go solar!!!
