I read though some code p3103.1 that now allows for installation over plumbing vents as long as there is enough spacing between the top of the vent and the panel and now the vents can be cut to 2" above the roof line. I will likely reroute these to go out the top of the panels so I dont have that venting onto the back of the panel. I tried looking for any existing posts if anyone has mounted over the attic exhaust vents though? being in az I cant imagine the heat from those will be significantly more than what the panel already gets exposed to. Is there any issues with mounting over the vents? I am running out of useable space on the roof attempting to maximize the production of the system. Thanks for any feedback
