Yes, those mounts and similar are on eBay quite cheaply. They can be glued to the roof so no holes means no leaks. Raising the panels lets air circulate for cooling. I was told that 25 degrees is the ideal temperature.

Yes, the panels rating is at 25 degrees. But remember it doesn't matter how much cooling you have on a 30 or 40 degree day, any panel, no matter how it is installed will be down around 10 to 15%. Also, no matter what gap you have underneath them, panels laid flat or almost flat like on a van can't vent the hot air very well anyway as the hot air rises and gets trapped under tye panel.
As for leaks, I've never had any from using ali angle like I have, using the right sealant - ie NOT silicone, will see you right. 👍
Drilling holes in the alloy angle would probably achieve the same cooling effect to a degree.
A temp gun reading of the glass and then the ally panel sides, and then Gavs ally angle would be interesting,,,
I’ll see if I can find my temp gun when I get home but it hasn’t been hot at all for weeks down here. Maybe 27 today but sunny, so maybe get a reading that means something.
What? Sorry - I can’t here you! [emoji15]
