5 Star Review - The Sun WorksHaving spent several months researching possible solar options for our new Sunshine Coast home we quickly learned exactly what it was we wanted to install, but the next piece in the puzzle, finding the right company with the best price and service options to back it up was far more challenging. With lots of companies happy to take your money but not necessarily happy to work with you to refine your selections and therefore your needs, we were thrilled to discover the sincerity and professionalism offered to us by Sunworks Solar. Our sales professional, Wayne, and his side kick Mike were always available to answer questions and nothing was ever too much trouble. Peter and his installation team were stunning. Despite a showery day and several interruptions, our job was completed and the final outcome was stunning – everything was so neat, so well thought through, so perfectly planned, so concisely explained. So, if you’re looking for the ultimate solar solution, we believe you won’t do better than Sunworks Solar in Maroochydore, a genuinely reliable company in a sea of uncertainty and hype.
