One thing I have done with solar hot water racks to spread out the weight per connection point to the roof and to give the upper and lower connections a stable point to connect to instead of just the roofis to do a uni-strut type frame that is parallel with
the roof and then attach the actual tilt rack to this parallel frame on the roof. It uses a bit more framing, but it also makes it super stable for Snow and snow retention or keeping snow from pushing up behind the panels
