Go Power 190W solar panel on curved roof

I have a 2018 Montana 3120RL which has a slightly curved roof. I am wanting to buy a Go Power Overlander 190W roof mount rigid solar panel. I am planning to mount the panels long edge fore and aft on the rig and to the left side of center to allow for possible expansion with another panel on the right side, if needed. The question is are any of you aware of someone who has done this on their curved roof Montana and were the supplied mounting brackets tall enough to allow for the slight curvature of the roof without the panel frame contacting the roof.

Thanks
Rick

I made my own mounts because I want to tilt my panels either way.
Pictures are from this post
From DIY RV Solar Systems FB group.

Lots of good ideas and info here.
You can also search MOC for pictures of installs.
I have my system built but I don't have my panels mounted yet. Too cold for the sealant to setup.
I do have them set out on the ground and I'm pleased with the output.
400W, 100/30 Victron MPPT feeding 552Ah lithium.
Ran the batteries down to 20% yesterday. Plugged in the panels this morning.

That must be really tough to replace a vent cover or clean the roof!!!

I went with 12 Renogy 100W panels mounted with their Z Brackets. They're easy to mount on a curved roof and small enough to locate them to avoid shadowing by vents and AC units.

Renology 100W panels are 14.3 pounds each.

The best I can tell our complete solar setup is about the same weight as a factory installed Onan 5500 watt and two LA batteries.
