Apparently mean insolation at the equator of mars is about equal to that at 75° latitude, well inside the (ant)arctic circle… and while Earth has winters where the sun is fully below the horizon, Mars has weeks-to-months long dust storms which block out most light.
So it’s probably a wash; Antarctica is at least not much worse than Mars for light while retaining all the other advantages of Earth like “air’ and” water” and “accessibility”.
Interesting question! It turns out that the Canadians are checking whether there’s enough light to grow tomatoes on Mars.
