At the end of April 2020 it will be 3 years since installation completion. Flawless workmanship, fully answering all my questions, and excellent engineering are distinctive characteristics of this organization. Plus, they're just nice people. I'm a completely satisfied customer. (I'd had 3 companies evaluate my project before I chose Sustainable Energy Group.)

Stellar solar guidance from start to finish - professionalism, expertise & knowledge off the charts. Committed to their customers, to their community and the environment. No wrong turns in working with this company - truly understand what delivering caring competency to customers means. Most professional crew I've ever engaged with as well. Stay calm and let's all solar on! :)
