5 Star Review - The Sun WorksI was very impressed by the sales process. I asked many questions which were fully answered, and requested several different quotations and options. The quotes were clearly documented and had appropriate additional technical materials appended. The final pricing was competitive and the responsiveness of the sales person (Wayne Deckert) was great which to me was an important factor. The installation team arrived at the exact time promised on each day and certainly gave me the confidence that they were specialists in their field. Overall I can most certainly recommend Sun Works to others considering a solar system. Our system was installed during April 2018.
