William;

That's some of the cleanest open array wiring I've seen. Very nice, but now the rest of us have to go back and clean up all our old work!
I also liked your method of quickly tightening connectors for flex conduit with a drill.

I agree, it should not be a two man job.(add that to the definition of accessible?) I would only think it would be OK to put a Jbox under the array, if it was a top down mounting system with modules small enough for one guy to handle.
I've changed out damaged modules by myself before on a system with ProSolar mounts, and it took maybe 2 minutes to unbolt and remove the old module. (4 bolts with a small electric impact driver)

Thanks for sharing your work and thoughts,
