My husband and I had Pure Energy Solar install a 4.8 KW solar unit at our residence in the Fall of 2007. Wayne and his staff were very knowledgeable, personable, and easy to work with. They came when they said they would, worked hard, and were a pleasure to talk to. The job was done quickly and professionally, and we have been enjoying the results ever since. We would highly recommend Wayne Irwin and Pure Energy Solar.
