The 1998 Solarex Solar Energizer PV System with Millennia MST43 amorphous
modules had an interconnecting frame with space in the C-channel frame for the
pigtails and quick-connects. In 2003, BP stopped the evolution of that product
line and then closed the factory putting 260 Americans out of work.

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.
