"Focus Electrical did a solar panel install and system hook-up at my business. James stands behind this work, and also does excellent Licensed Electrical residential work. Based on his Return On Investment figures he presented and the current system operation, this system will have itself paid for in 5 to 6 years. Highly recommended!"

"A family of raccoons took up residence under our solar panels and caused significant damage to our roof. I initially tried to arrange a solar panel inspection with the company that installed them for us, but felt like I was being given the runaround when it came to quoting and scheduling the work, so I gave up and decided to take a flier on Green Sun Energy, and I'm glad I did - they quoted the work, we booked an appointment a few days later, then they did (as best as I can tell) a thorough inspection of the system. I intend to hire GSE again for related mitigation work later this summer and would highly recommend them to others who may require their services."

"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."
