Solar wiring through vent, how to seal hole in vent line
I had to bring the wire for my rooftop solar panels down through the kitchen sink vent pipe. I drilled a 3/4 in hole to fish wire through; how have others sealed this hole?? Thanks, Doug

Done properly, there is no reason to fear punching a new hole in the roof. Often times it gets you to your ultimate location using less conductor resulting in less voltage drop. There is already at least 6-7 penetrations in the roof from the manufacturer. Everything is available to do as good or likely better job of penetrating and sealing up the roof then the manufacturer did. It is a good fear to overcome, then you will have more experience and confidence to address future plans or issues regarding maintenance to your roof..........my opinion of course, not looking for a fight.
