I wasn't talking about the performance of solar, only the demand for electricity.

Someone pointed out that the big problem with solar isn't how do we store daytime solar for nighttime use - this is easily solved with batteries. The real unsolved problem is how do we store summer solar for winter use.

Australia doesn't have this problem, not to the extent of other colder places, because we don't need a lot of heating in the winter.



Seems like there are lots of approaches that are technically viable for seasonal storage, hard to work out which one is better cost wise.
