Joel:
I am waiting for module manufacturers to incorporate a slim gutter along
the short edge of the module. In the gutter can be folded the PV cable
with quick connects. This tray would have KOs in the ends and sides,
allowing snap bushed connectivity to adjacent modules and conduit to
connect for PV feeders.

Most solar module designers have no field experience. Some design solar
module long-rail angle or channel frames that bow unless you fasten them
to the mounting structure with 4 bolts (2 per long-rail) in
factory-drilled mounting holes. Some long rails are so weak that they bow
under the module's own weight if you just lift the module by the long
rail. Solec modules had a tube-frame that was the strongest in the
industry, but I don't recommend Solec type frames. They were over-built
and required threaded inserts and a special insert tool if you wanted make
your own mounting holes (which you were allowed to do without voiding the
warranty). There is no reason for poorly designed and weak angle or
channel frame extrusions. A strong frame gives installers the freedom to
drill their own mounting holes in both the long and short rails.
