After four years in the Skoolie Community, I have seen everything regarding solar. This is by far the best method I have seen for mounting a solar array as it is simple, strong, versatile, and offers full coverage of a rooftop reducing the heat load and thermal transfer into the bus. The system can be bolted through but I have yet to run into a circumstance where this has been needed and with zero failures, I have no reason to do it at this point. Oftentimes I am installing solar onto a bus that is already built out with the ceiling enclosed already. This system resolves that.
