"Granite State Solar was great to work with. We were thinking about going with a generator for backup power. They helped us explore solar with Batteries. Not only do we not 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. I would use them again for any system additions or recommend them to a friend." —Ross S.
