Cable Penetrations - Corrugated Colorbond Walls

[VK5TM]

I can't get on the roof (corrugated iron) to get a photo, but the solar installers used some sort of seal to pass the panel cables through the iron.

Might be worth a bit of searching to see if what they used can be identified and if it is of any use.

A second thought (and one I've used before) - is there any gap between the wall iron and roof at the eaves that will allow feeding cables in?
