ICE - I thought the diagram was required for PV arrays with rapid shut down. Are you seeing rapid shut down on all of them? The labels in the picture do not indicate Rapid Shutdown.Missing is the placard with the roof layout showing the array. The plans will generally have a sheet of what sticker goes where.

So far I have only encountered rooftop arrays.ICE - What I read Rapid shutdown is per 690.12 "if on or in a building shall...." Do you not have any pole based systems non rooftop or wall that have sun tracking etc.? I had one project that had both roof and wall arrays and at the time I wondered how is the person walking by an array or a rooftop maintenance person protected or is the only concern for first responders? Up here we have long handled snow removal devices.View attachment 7305
I guess he doesn't know PhotoShop!I was sent this picture by a solar contractor. I noted that the stranded wire shows damage.

The contractor disagreed with that assessment so I sent him a picture. He still disagrees with me. He claims that what I see as damage is an optical illusion. So I asked him to eliminate the optical illusion.
