It’s wonderful when you find a contractor that says what they will do and when AND THEY DO EXACTLY THAT. I am over 70 years old and have hired many contractors in my life, but Premo Solar is on the top of my list of the best. They came out and surveyed our roof, suggested a proper system, drew up the engineering drawings, got PGE and the city to sign off on the design, and all with minimal effort on our part. The system is up on the roof generating electricity and it is mainly due to Premo Solar’s efforts. I highly recommend Premo Solar.
