Evolution of the Quick connect [RE-wrenches]

Phil:

Protecting wiring behind a PV array is easier than most folks realize.  We 
have been using Solar World since they were Arco and, until just recently, 
the modules all had j-boxes with 1/2" knockouts.  We covered our wiring 
with conduit and developed techniques which allowed us to install 
connectors onto non-metallic liquid tight in about 3 seconds.  Total cost 
of materials is about $2.50 per module.

Here is a link to a few photos that illustrate some of the concepts:

We had arrangements to purchase Solar World modules with the J-boxes until 
just recently, but now we are forced to use modules which do not allow us 
to remove the USE cables.  We are now developing procedures to protect the 
USE cables without the use of conduit since we no longer have knock-outs to 
connect conduit to.  We are pretty much on-line for ground mounts as 
pictured in the above link, and we are working out procedures for keeping 
roof-mount wiring safer than other installers do.  This will be a market 
niche for us capturing the high-end and safety conscious consumers.

We are hoping advances in the NEC and local codes will force the 
manufacturers to bring back the j-box.

Please feel free to contact me off-list if anyone has questions.
