"I spoke with the owner George on the phone about possibly only an install of solar panels not buying product through his company. He spent the time to explain the process and concerns he could see with my plan. Based on his willingness to spend ample time explaining the process I ended up using his company for the complete project. I am more than satisfied with the end result. The company did not sell me unneeded equipment and kept me informed throughout the whole process. They completed all the necessary paperwork for the state which included the $1000 rebate from the state of New Hampshire. Quality workmanship and great customer service. I would absolutely recommend this company for any person considering going solar!"

"Highly recommend Green Sun Solar. They were very responsive, professional, with good communication and follow up. Provided reasonable estimate for repair of roof top solar system, repaired system within a few hours and final price came in below their estimate. Couldn't have asked for better service."

"Professional, responsive, and efficient. Sunup Solar designed and installed our off-grid system during late winter and fit into our time crunch to move into our new home. We are ecstatic to show photos and tell others how an off-grid lifestyle can be modern, and in our case, even within sight of on-grid neighbors. During the hottest days we run AC without worrying about a power bill, and when a summer storm hits our lights never go out. Our home has become an example for countless family and friends to consider building off-grid, and we continue to recommend Sunup Solar to folks across New England. Thank you Hunter and your team for powering our dream home."
