Glen and his team completed a Genrac generator and Solar System installation. The team did a fantastic job. They are very reliable, walk you through all the details step by step, communicated clearly, and completed the work on time. They will help you through design, permits, inspections, various registrations. They can help with financing and suggest best options. They are in for the long haul and more interested in maintaining a relationship with their customer. Glen walked through the cash flow details of financing a solar system vs leasing to help me make the beat decision. They are also local which helps compared to big name corps. Overall highly recommended

Green Sun was excellent to work with in purchasing and installing our Generac. Glen fully explained the entire process, handled the permits, worked with us when I made a last minute change to the plan, and brought in an exceptional installation team. He has remained available with any questions we have had since installation over a year ago, his team monitors and services our Generac, and Glen has been nothing but kind/knowledgeable/helpful. Highly recommend Green Sun and we thank them for ensuring our home stays protected.

Excellent installation of our Generac generator, and fantastic regular maintenance! So happy to not be concerned about tropical storms and other events cutting our power here on the shore!

Great experience with Green Sun Energy. The install process was streamlined and worry free. The electric and plumbing contractors were professional, showed up on time, and cleaned up after they were done. Glen and team kept me well informed during the entire process and promptly addressed any questions or concerns I had.

Green Sun kept in constant contact with email/text updates, made aesthetics a priority, and even arranged financing options. Everyone I met/encountered on the team was professional and helpful. Though there are many solar companies who work hard to market/sell, I reached out to them after looking around a while. When I did contact them, there was no hard sell, just presentation of what I could expect if I proceeded with the project (which, obviously, I did). Highly recommend Green Sun.
