Gerald Yuh and his crew are no doubt professionals in the truest sense. His initial visit with us to share his knowledge about PV systems and the thoroughness with which he planned to install our system with the best of material convinced us to select him to do the job. His experience and knowledge as an electrical contractor was refreshing after listening to so many sales presentations. We are very pleased with the PV system he has created for us. I would not hesitate to recommend him to our friends.
