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.

Matt checked the system thoroughly and educated us on how the interface between the solar and the net meter works. We are very pleased and may be back to him for more services

Matt was very helpful from the beginning. We had extensive damage from squirrels being under the panels. They chewed up all the wires and ruined all the optimizers. We're lucky there wasn't a fire and I wasn't sure we could afford to fix the panels! Matt helped identify the work that needed to be done and also was helpful in helping me identify that the roof should be replaced while the panels were down. He was super patient as we got various estimates on the roof and then had it done. After giving me an estimate for the whole job he fulfilled my requests for itemizing the estimate and was great at explaining each item. He did the job for the exact number on the estimate. He and his partner fulfilled everything on the estimate and over-performed by recutting some the brackets to make them exactly even that our original installer Boston Solar did not do when they were installed 10 years ago. I called Boston Solar this January when we realized the damage the squirrels had done and they gave me an estimate for the work. Boston Solar gave me an estimate for just taking the panels down, doing a diagnosis and reinstalling them. This did not include the repairs and parts which are the expensive part! I'm so glad I got a second opinion! For the same price Green Sun Energy took the panels down, diagnosed the problem, fixed all the panels by replacing all the optimizers, MC4 connectors, wires, flashing kits, reinstalled the panels AND added a Critter Guard. Matt and Green Sun are definitely experts in the field. THEY ARE HIGHLY RECOMMENDED!!! THANK YOU MATT!

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.
