Solar works as well as it does only because we’ve spread it out and connected it to a grid. When it is overcast in one spot it is sunny elsewhere.

That “elsewhere” has to be far enough away to get different weather.

This means a grid capable of transferring 100% of the needed power.

So even if you plopped a new DC in the middle of a field of panels you’d still need a ~1 GA grid connection… or a battery array many times the size as you’d otherwise need just to cover night time usage.
