In 2008, a local team in Bow, New Hampshire set out to bring clean energy to Granite State homeowners who wanted a better way forward. Granite State Solar was founded with a straightforward mission: make solar installation simple, transparent, and genuinely focused on what matters to New Hampshire families. From that first residential solar panel system to today, the company has grown organically into one of the state’s most recognized solar installers—serving homeowners and businesses across New Hampshire and Vermont with the same hands-on, no-pressure approach that defined those early days. Based at 57 Ryan Road in Bow, Granite State Solar has built a reputation on local expertise and genuine customer care. The company has earned recognition as Best of Business for solar for nearly a decade running and has been voted Best of the 603 every year since the competition began in 2021. With close to 200 five-star Google reviews and a BBB A+ rating since 2018, the solar installer in Bow has proven that doing right by homeowners pays dividends. The team comprises in-house master electricians, certified installers holding Apprentice, Journeyman or Master Electrician credentials, and a dedicated service department—no subcontractors, just experienced local professionals who understand New Hampshire’s weather, building codes, and permitting processes. Granite State Solar specializes in residential and commercial solar installation, offering both rooftop and ground-mounted systems custom-designed for each property. The company also installs battery storage solutions including Tesla Powerwall systems, Generac standby generators, and EV charging stations—creating complete home energy systems that deliver independence from rising utility rates. Every project begins with a free site assessment, where solar advisors take the time to measure, evaluate roof structure, check electrical panels, and understand energy goals without the high-pressure sales tactics common in the industry. New Hampshire homeowners considering solar panels face unique challenges—long winters, variable weather, and the need for systems that can handle heavy snow loads. Granite State Solar has spent nearly two decades perfecting solar energy solutions for this climate, and their track record shows it. Installation crews work efficiently, with many customers reporting complete roof or ground installations finished in a single day, including trenching and electrical work completed in as little as six hours.
