Defreitas Enterprise's is the rare company I feel compelled to leave a review for. Removed a tree safely with some additional experiences we all benefited from. If you're questioning the Enterprise's merits I will say they are improving the universe.

Alex and team are very professional and will do the job with utmost care and concern for the customer. I’ve had DeFreitas Enterprises contracted for two solar systems and I can say with absolute certainty that I am thoroughly impressed with the work performed.

Alex is very professional and provides exceptional service. He walks you through every step of the process and is very approachable. I was looking for a smaller local solar panel installer with a more personal experience.. Alex-Sun provided that, and more! I would recommend Alex-Sun to anyone looking to "go solar" in MA or NH.
