would be easy to do so. Pythagoras solved it ~2500yrs ago. That and a little Trig (2300yrs ago). All you need is a base edge pivot setup and a pivoting leg or stirrup that is mounted on both 'side' edges, with that 'base' leg sized to match your panel to the optimum angle for your latitude. With an appropriate slot setup in your mounting frame all you'd need is a couple wingnuts / threaded hand knobs, loosen them, lift up on the high edge of the panel until the linkage maxes out, then tighten them. You could even add a pneumatic arm so all you'd have to do is loosen a knob and the panel pops open to height. YOu'd just have to push it flat and tighten
This could almost work for me mounted vertical with longer or extending adjustment poles. Problem I see is with the panel extending past the pivot point it won't go up past level
Keep ideas coming, thanks
Here is a pretty slick sliding setup. https://oriondesigns.ca/
