Granite State Solar has been awesome to do business with. From the first phone call they were very responsive and informative about their solar program and generators as well. They performed the solar work needed for my system and got it up and running quickly. My generator was installed just as seamlessly and once everything was inspected, was tied in and will now provide all of the power I will need if the power goes out.
I know there are many solar companies out there, but Granite State Solar's reputation speaks for itself and I would, without hesitation, recommend Granite State Solar to anyone looking for a solar system or generator for their home or business.

I am very happy with the install of my solar panels and battery backup system that GSS installed. From the initial consultation, to the install process, and the final post install review, they did an excellent job. They answered all my questions I had in a timely manner during the whole process. I would recommend GSS to anyone.

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.

Great experience, so glad I moved forward with Solar. GSS made it a seamless process from quote to go live. The panels look great on my roof and I can monitor everything from my phone.
