Sunergy is great. They are extremely professional, and their solar installation has worked flawlessly for me. The price was good, they helped with financing options, they were great. They did what they said they would do, no nonsense. I would do it again!

The install was easy and smooth. Greg was excellent in answering all my questions and doing a last minute redesign to increase the capacity of the system! And its a bonus that they are employee owned and local - kudos all around.
