Get matched with top solar pros in Williamstown, MA

"Sun Bug is a 5/5 star company. I inquired with 4 solar companies and these guys stood out from the pack from day one with a responsive fast estimate, scheduling that was easy, and an installation crew who arrived on time, were neat and cleaned up every day. They did what they said they would do when they said they would do it and now my new solar panels produce enough energy to cover the average daily use, just as they planned. You must call them before you buy."

"Worked with Stephanie, the project solar manager to achieve desired efficiency of the solar project. She's is very personable to work with and highly motivated to get the best results for your solar needs."

"Installation by local company, Mendocino Solar, was great. Continuing Service when needed has been great as well."

"It was pleasure to work with the All Energy Solar team for the design, installation and post installation support of my home solar power system. Every aspect of my relationship with AES was professional, supportive and actually fun. Working with Justin Growel on initial design was smooth and informative. My project manager, Carlo Maloni, provided excellent support before, during and after installation to ensure that the whole process went smoothly, including all necessary permits and inspections with local government and our power utility. I can't say enough about the excellent installation crew who were total professionals as well as friendly and answered any questions that I had during the installation process that only took a few days. I will definitely recommend All Energy Solar to other home owners looking to install a home solar system!!"

"It was okay. I think I spent an additional $600. I liked their crew, the owner himself Anthony Berry and he had a person with him. I thought the work that they did was very well done. They cleaned up after themselves. What I didn't like was the fact that they didn't have the supplies that I needed in order to get the job done and then one of them had to leave 3 hours and go get supplies. I was paying for that whole time so it was a little disappointing to me that what I thought could have gotten done fairly reasonably quickly ended up taking a lot longer. My interaction with them and their work were good. I think they should have called me ahead of time and I would have told them what work I wanted done so they could have been more prepared. I felt that they were a little bit unprepared for what I needed done so they just need to be more prepared in terms of having their supplies and stuff. I will not use them again simply because he's actually located very far away like I'm at the very edge of his service area. He's located an hour away and there are other providers with closer proximity to me."

"They were unable to perform the work but were very nice and gave me the information I needed to ultimately get it scheduled"

"They are in the process of sending out an engineer"
