German solar: 10 hours of sun in December makes 40 Gigawatts of nothing

From Pierre Gosselin at No Tricks Zone:

Germany needs 80GW of electricity. It has 40GW of installed solar PV.

See the graph: The red line is what the country used, and the orange bumps are the solar contribution.

Clearly, solar power will take over the world.

In December, Germany got ten hours of sunlight. That’s not a daily figure, that’s the whole month. So in summer on a sunny day, solar PV can make half the electricity the nation needs for lunch. In winter, almost nothing. From fifty percent, to five percent.

Imagine what kind of havoc this kind of energy flux can do. Not one piece of baseload capital equipment can be retired, despite the fact that half of it is randomly unprofitable depending on cloud cover. Solar PV eats away the low cost competitive advantage. Capital sits there unused, spinning on standby, while wages, interest, and other costs keep accruing. So hapless baseload suppliers charge more for the hours that they do run, making electricity more expensive.

They just need batteries with three months supply. It will be fine once Germany turns the state of Thuringia into a redox unit.
