Premier Improvements was a pleasure to deal with. They were extremely knowledgeable and informed about the industry, various products, and incentives. Adam and Brian had excellent communication the whole way and were always very responsive to texts, emails, and calls. The installation looks great and the Sunpower panels are gorgeous. I would highly recommend!
