i have the roof sprayed by rvroof.com so I've been thinking along these lines off and on. Didn't know about these purpose made brackets though. I have just been contemplating sticking down some flex panels, or perhaps rigid ones...low profile right down on the roof
I figure mine is a good bit stiffer and stronger than just the TPO sheet
or I've thought for example on top of the AC shroud I could put a small flex panel
I just hate the idea of drilling through my caulk-free roof.
When I had it done they told me they would re-spray for anything like this if ever needed....but I'm not sure if they meant for a price or not. Regardless it's as much about the hassle of getting it there, dropping it off, etc...
I've also considered looking closer for a way to perhaps attach some metal structure bridging between two existing hard points...such as the AC frame and a roof vent/fan....then attaching solar to it.
In the end, I really dislike adhesive type connections. So many things that can go wrong. I'm a mechanical guy, and just feel better about mechanical fasteners.
so I keep coming back to just screwing the things down and then someday getting those spots re-sprayed by rvroof.com....IF I ever do get around to doing solar...
