Less manpower using a winch or a block & tackle.
Kinda like the green unit, but without the extra leg. Just two pipe supports, with a cable between the feet.
If you could make this light weight, but strong, it could be moved between
arrays, hooked up, tension taken, then loosen up supports and lower or raise the array, tie-off and re-tighten the supports.
The Bi-Pod would be leaned against the north side of the array.
The upper edge of the array would slide against the pipes.
I used a jury-rig block&tackle to install my 4 panel array..
Used it to push the center support arm upwards, I'm too old to lift heavy stuff.
