German Solar Energy To Be Turned Off Tomorrow

It’s hard to say how long the grid will be down, though.

Eclipse

So what’s the big deal, exactly? The sun goes down every night, of course, and Germany is quite accustomed to cloudy days. (It gets about as much sunshine as Alaska.) The difference with a solar eclipse is the speed at which sunlight will disappear from, and then return to, the power system. All electric grids operate on the fundamental principle that supply and demand must always be in perfect equilibrium, second by second. That dynamic becomes complicated when so much of your power comes from a source like solar, over which grid operators have zero control. And it’s especially tricky when the fluctuation is so rapid and extreme.
