On that, when you buy the fancy 25 ft or whatever long MC4 cables to plug your fancy MC4 panel pigtails to, are they also aluminum? So what is their real AWG value? Phooey. I will stick to doing my own wiring; at least that way I know what is going on.
The one's I found on Ebay are copper.

Is there a way to tell if they are cu or al with those MC4 cables without cutting them?
If there are wiring standards printed on the insulation, you might be able to tell from that. Take a pic of your wiring and post it here.
