Granite State Solar
Granite State Solar installs whole-house generators and home battery backup systems, working from Bow and serving Concord and Auburn in New Hampshire.
What they do
Granite State Solar installs whole-house Generac generators across New Hampshire and also fits home battery backup systems, including Tesla Powerwall units, alongside solar arrays. Work starts with a site assessment of the home's energy needs, which sets the generator size, followed by system design, installation and final testing. The company is based in Bow and lists Concord and Auburn among its towns. Financing is available for projects. Panels and inverters carry a 25-year warranty, and installations come with a 12-year workmanship guarantee. An in-house service team handles maintenance after installation on weekdays.
