Mick Collins – Solar Customer in Penn Valley, CA

Sustainable Energy Group was incredible in all phases of our project. The initial consultation was informative and went over all of our options based on what we wanted to get out of a system.
  They never pushed one option over another, simply provided us with the information we needed to make our decisions. The design and installation crews we’re efficient and professional, and I really appreciate the monitoring of our system. They let me know that I should trim a specific area of a specific tree to catch more rays.
  I highly recommend talking to these guys if you’re considering solar, either residential or commercial.
