I'm trying to keep my physical arrays homogeneous. More visually pleasing that way, and rails line up better.
(even if they are misaligned, for mechanical and historical reasons. I'll try to straighten that while I'm swapping in higher output panels, "over-paneling in place".)
After much pondering, I figured out how to most efficiently use the rails and clips I've got to hold the replacement panels in portrait orientation, and fit whole numbers of strings per array.
