HI Power Solar has been thorough and communicative from the start. The process was clearly outlined and John Yeh was always there to answer our questions. Every time we called or messaged with a question, John promptly responded! HI Power navigated the planning and permitting process, and the team who installed was professional. HI Power Solar made the process smooth and easy and established a relationship with us that we will carry through the lifespan of the P.V system.
