Great communicative team who were very upfront about current technologies, project details and steps in the process to install a whole home battery backup system. I'll certainly be collaborating with them again in the future on projects related to the electrical system.

So impressed with the quality of the work, the education imparted, the communication with us and the various agency's, all at a much better price than the competition.

I waited for far longer than most customers to post my review. I knew I was going to use the tax credit from the solar array (2025) and battery install to pay for what I thought would be a second battery but was actually a batter expansion pack. Who knew!
Every interaction I have had from Andy coming out to our house in really early, really cold 2025 late winter to look at options for installation to every person I've interacted with by phone, email or even text has been professional and comfortable. Nobody is reading from a binder and if you've had any type of service work where EVERYTHING is straight out of the binder then you know how undesirable that is. Also no shame in not knowing anything. Like I don't know the job progression, but nobody made me feel like a bother because I asked what is happening now.
The onsite work has been some of the best work I've ever paid for. Everyone is professional, the work is clean and tight and more importantly my husband who has been in the trades for more than 40 years approved across the board. We had a water issue. It was an issue the company did not just shrug and walk away from. Probably unique to my property. But the take away is, it was a problem and they kept after it until it wasn't a problem at all.
Alright, so lets talk solar now. I am very happy with the number of panels, the initial battery (even though I didn't tell Andy I was planning on a 2nd battery so he had no idea we'd be modifying) and all of the interactions I've had during the install of all of that. Ashlee helped me work out a problem with the power wall. Most companies would wash their hands of your issues once the install was done, you figure it out!
If you want to have it done once and right, you pick a company that has a record of that. I picked the right company! This is a huge financial investment and making the wrong choice can make your hard earned money be wasted in the worst way.
I couldn't be more pleased with my choice.
I usually leave reviews for anything I consider "the trades" to my husband because he is far better at the salient points but I wanted to weigh in on this one myself even though I'm not as good as he is at saying WHY this is a good choice.

Granite State Solar did everything they said they would in our preliminary meeting. They expedited all the permits and kept us informed every step of the way. They finished on the schedule we agreed to, enabling use to complete the project before the federal tax rebate expired. Thomas and Ashley were knowledgeable and patient with use through all of our questions. They were also helpful in setting up the apps we needed to monitor our new system. The people who installed our solar system were professional and conscientious.

From beginning to installation completion GSS was great to deal with. I was a little leery of having panels installed, not because I didn't want them, but because I had doubts the panels would ever pay for themselves given the orientation of the house. But after discussions with Andrew about the types and number of panels and rebates (which Trump killed after this year) I decided to have panels installed.
Installation took 1 day and is super clean. I'm very happy with the looks of the installation. I'm also pleasantly surprised by the output of the panels. Granted, this was based on the time of year is when the panels were producing peak power, but still, they were producing more than I expected.
I also appreciated that GSS handles all of the permitting and dealings with the power company. I only had to sign one set of electronic documents.

We recently hired Granite State Solar to install solar panels in our home. The entire process, from proposal, to installation, to follow-up summary was excellent. Our contact, Andrew, was very special. He listened well, answered all our questions, and demonstrated that he has a decade of experience. We highly recommend GSS without reservations.

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!!!
