Wrenches, I see that this topic was discussed back in 2015 <https://www.mail-archive.com/[email protected]/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?
