10-100+ MW of panels?

That might take a week. You're right much worse /s

I haven't looked into this deep enough, but my assumptions are that currently the supplychain for getting and installing these systems takes much longer than coal, which is a much more mature supply chain, and also not limited to China's production. If solar panels were as cheap, quick and available as coal, there'd be literally zero reason why people wouldn't use them over coal, but we know there are enough places that still use coal IE Germany.

I'm not sure what you're talking about. Solar panels are cheap, quick, and available. China is practically giving them away.

You can have as much solar as you want but without batteries you will still need alternative sources.

Also there is the fact that there simply isn’t enough sun in most of Europe in winter regardless of how many panels you install
