"Option One Solar installed our system approximately 3 years ago. It has taken me some time to write and frankly I think it will serve potential customers even more. They truly have stood by their work. Number one the installation process was very professional, from the office employees to those on the ground doing the work. They kept us informed, detailed any problems with the city, site, etc. When there was a slow down, etc they described it and solved it. I really appreciated that. And now that the system is running they have stood by it. I highly recommend them."
