Why does the wiring of PV panels have to be copper? The wiring (aside from the contact wires actually on the cells themselves) is not volume constrained, so I'd expect aluminum to be used, not copper.

that's even more energy intensive and expensive, I guess

Aluminum is cheaper per mass than copper, and has higher conductivity/density. Aluminum is orders of magnitude more adundant in the Earth's crust than copper.
