Looking for Lower Cost Copper wire (8-10AWG) from Panels to Inverter Connection

It seems that every time I find a good price on "copper" wire, when I look in the fine print, it turns out to be copper plated aluminum wire.
Where can I buy real copper wire for long runs from solar array to inverter? I estimate up to 100' runs. I'm looking for a zip cord that's red/black color coded/polarity marked, if can be had reasonably. I'm probably likely to use two sets of cables as I'm splitting 40 panels into 2 arrays.

So you want "zip cord wire"? Will this be in conduit? I think only black USE2 wire is UV protected for direct sunlight. Perhaps PV wire can come in zip cord...

I'm doing a rather experimental setup, which, if successful with the amount of sunlight we get, may be upgraded to a more permanent setup. I like the red/black zip cord because a blind old man like me can see which wire is positive and negative fairly easily.

I have a good bit of 10 gauge solid wire I picked up years ago from household wiring remnants. Some near full 250 foot rolls. I'm in Missouri don't want to ship, but get east to west pretty often along the I70 corridor. And travel to Cincinnati and Florida at least once a year. Greenville SC often as well.
I'll bring a propane torch, I think you can melt aluminum but not copper with a propane torch.
