... provided that you can store a sizeable amount of energy (what do you do when there's no sun for a whole week, which is absolutely not uncommon in Germany?). There isn't any technology up to snuff, unless maybe flooding a very large Alpine valley to build a STEP.

Batteries for overnight storage, Hydrogen or Methane for seasonal variations, various types of heat storage for heating and cooling. And demand shaping of course. It's mostly a matter of cost as far as I know.
Of course you'd want to rely on wind power more than just going all in for solar in Germany. It's not a particularly sunny country.
