Yeah that's actually very close to what I am thinking, if I get some expensive high value panels, I'm at a fairly high latitude (46N) so the winter-summer angle difference is extreme - winter 69.77 degrees, summer 17.27 degrees. I plan to do it with something like angle iron and fasteners but it's a big angle adjustment. I may actually hang them on the side of the barn with standoffs at the bottom in the winter, and in the summer lay them flat on the ground.
