[RE-wrenches] Integrating with Lightning Protection

[Corey Shalanski]

Wrenches,

I see that this topic was discussed back in 2015
<https://www.mail-archive.com/re-wrenches@lists.re-wrenches.org/msg19683.html>
and there were some excellent resources shared on how to electrically
integrate PV arrays with existing lightning protection systems (LPS). I am
curious if anyone has any advice about how to physically/mechanically
integrate a commercial rooftop array with an LPS—particularly wondering
what to do when we encounter a network or web of LPS cabling laid out
across the roof. I am assuming we should not simply move the cabling
without first consulting with the LPS contractor... Can a ballasted racking
system viably be placed over top of the cabling? Can ballast bases be
placed directly on top of the cabling? or be made to somehow span over or
be elevated above the cabling? Or is this just a case where we need to
limit the PV array to whatever areas of the roof offer the least
interference/convergence with LPS cabling?
