Hi, we built our own panel mounts. We needed extra strong mounts because of the typhoons we get here and the fact that the panels are mounted 3 stories up. We used 2 inch galvanized tube as the mount and angle bar for the brackets, they swivel on the tube and are adjustable by angle bar brackets to another tube. They are a really simple design it takes us about 5 hours to build one. That's about it. the dog
