Panels over vent pipes?
Our roof is being measured this afternoon for our 7kw system. The radon and sewer line vent pipes that extend about 18" through the roof in places where I would like to have some panels. Is there any reason why I shouldn't cut off these pipes to about 4" long so the panels can mount over them, still leaving about 2" of clearance between the top of the pipe and the underside of the panel? I asked my plumber about it this morning and he didn't see why it would be a problem, but of course he doesn't know anything about pv. He said the only reason they are so long is so they don't get covered with snow. I'll ask my installer about it this afternoon as well, but would be happy to glean from anyone else's experience and/or expertise too.
