Remember to use only black cable ties and black plastic clamps. They withstand sunlight and heat a lot better.

Thanks for the tip.

I happen to have a roll of Eternabond on the way. What do you think of using some of it to secure the wires to the roof between the panels and the vent I will use to route them to the basement? The run to the vent is about 3 feet.

You need to secure the wire so wind/ travel speed doesn't interfere with it's positioning. Eternabond will probably hold MC4 down to an EPDM sheet, especially a short run of 3'. There are wire clamps,holders that could be fastened to hold the wires but I understand the fear of putting even a small hole through the membrane. I would have no problem with that since there are such good sealers available and aren't the brackets for the panels fastened through the membrane? That's just rhetorical.
