That's too many separate poles, they get to be a real hassle at more
than two (and costly too). I'd go to a multipole mount arrangement,
(here's
one:http://www.dpwsolar.com/index.php/applications/commercial/9-commercial/17-multi-pole-mounts-g2-mpm-g2
and then all your cabling won't have to jump up and down, it can just
run the length of the array framing. This is more how all large ground
mount systems are going these days. Otherwise, you need to bring all
the poles into a centrally located combiner, possibly at one of the poles.

Hi Wrenches, I am installing six 8 panel pole mounts in a grid tied system. My
question is about preference for cable run between the poles. I am interested
in industry best practices. I have been told that running conduit between the
poles, i.e. along the axis, will hold the cabling but the poles of course must
be precisely aligned. The alternative is to run cabling down the poles,
underground and up the next pole. This is wasteful of materials, expensive to
the client and in my view presents as many safety concerns as the other option.
Hope to hear some ideas.
Ron
