Mine were fixed at 33-degrees for my latitude, at true-south, and also fell off in the summer.

Yes Solar Cells like to be cool.
More efficient and higher output. Longer lifespan.
There's all sorts of studies and videos on cooling them:
Water sprays from above and below.
Heatsinks and water cooling blocks.
Damp clay. (evaporative)
Low Watt Fans. With and without the above.
etc-etc.

I think a generous gap between them and the roof, or whatever they're mounted on, for any breeze to get under is a simple start.
On the ground in dry areas; Well watered shade plants so you get leaf evaporative cooling in said 'under breeze'..?? and over..??
Lush gardens are just cooler where its dry.

Then that solar reflective paint if there's any excess roof or ground surrounding the panels.
And especially if they're Bifacial.
