Important to remember as we had to nowhere on this discussion: The panels are designed for a very high wind load, even when statically mounted: think storms and other natural occurring wind events. This will cause loading, lift, vibrations etc as well. Not to mention impact residence for hail.
Me, if I have room for big, higher voltage panels, that's what I'm putting on. If one fails, it will be a few years down the road most likely and then I'll have learned my lesson will will invest in newer and likely cheaper technology.
We often spend a lot of time worrying about things that aren't worth the effort of worrying about them.
