Very good idea for the cost-conscious consumer and installer! It could
also lower PV module cleaning and maintenance costs by dramatically
reducing pigeon, squirrel and other avian or rodent populations that
foul PV arrays and chew wires.
My consulting client at our meeting this morning said h
Besides saving copper you've also solved the squirrel chewing conductors
problem!! Anyone have good recipes for char-broiled squirrel?

I've oft wondered why we didn't use this time tested automotive wiring method
more in PV; especially at higher voltages.
An energized roof is a happy roof as they say.

I am installing a PV array at about 400Vdc on a metal roof. The inverter
is located a very long way from the array. I am contemplating just
running a positive conductor for most of the run. I was thinking about
connecting the negative PV conductor to a lug solidly bonded to the
metal roof material.
