Exactly. Any mechanism that moves the panel to follow the sun, must be sturdy enough to also withstand high winds, which is inevitably costlier than proof of concept ideas.
Better to add more panels.
A better way to ensure more power output is to have a set of panels with a small battery back to automate cooling of the panels and cleaning of the panels.
Interesting that the limiting factor is energy and wind. I wonder if you could devise a locking mechanism or something purely mechanical to solve it. Something closer to gears in a watch.
