I guess the thing is that installing batteries at a large scale only really makes sense when you have a lot of excessive solar energy that you want to store, and we’re simply not there yet. China produces sth like 10% of its electricity from solar these days, and that’s simply not excessive enough to make it worthwhile to store the excess solar energy production. It’s all consumed immediately, almost. Only when we hit like 50% solar energy generation, will there be excesses significantly enough to consider storing them, is my guess.
