I'm replacing a roof solar sensor, and I don't know what kind of wire to use in such an exposed area.

I wonder if anyone can advise me as to what wire to use on my roof sensor. Obviously it's in the wind, rain, heat and cold, so it has to be pretty rugged. Home Depot is fine if you can recommend something they carry. Amazon, E bay works too. I only need 75 ft or so to be safe.

Thanks in advance...

Can run in conduit or Type UF-B Which you can bury in ground, outdoor, wet or dry locations.

That would be my last choice... I’m just looking for wire that has insulation that will hold up.

The sensor has a small pigtail attached. Just cut the old one out and use heat shrinks to butt splice the new one on. Wire insulation is rugged it lasts a long time outdoors it just fades. I have a huge roll of 18/2 I use for valves and such that's held up great I get from supply house.

I think I used a type of door bell wire, which has two layers of insulation, but was careful to hide it from the sun (under panels, under pipes, etc). I can't now remember if I used zip ties or not. Don't. If I did, I'll have to get up there to replace them (they don't hold up in the sun). I was writing in another thread, this is what I now use outdoors to fasten stuff to other stuff, very handy to have around:

Ill go that route! Thanks for that. I actually have some non fluxed welding wire I’ll never use again that should be a good substitute for SS ties.

Thanks again!
