I had a panel on the C's roof up front just back from the front cap and almost lost it from wind effect while driving. It wasn't mounted as well as it should have been but it did go to show how strong the pressure is there.
(I heard it hammering, and was able to pull over in time--lucky!)
Our front cap is fibreglass or whatever it is, and the roof is rubber on wood, so not the same for mounting things. I would not try that with our front cap.
Perhaps you could get the same thing for the morning low sun by rigging the front roof panel so it can tilt. There have been posts showing how guys have done that with roof mounts.
