Excellent customer service. I spoke with Rein over the phone, he was very pleasant and accommodating to my expectations. I recently had a contractor come out to paint the exterior of my home and had noticed overspray paint on my new solar panels. Rein assured me that his company will take care of the overspray and cleaning of my panels. He was able to make an appointment for me the next day. The next day Mark and Jerry C. showed up to start the job. They were quick and detailed on their cleaning. I am completely satisfied with their work and would recommend them as a local, professional solar cleaning company.
