alt Hacker NewsWorst I've had over a day in the last few months on my home solar is about 25% of my maximum daily generation. It was one day in a very rainy week here in Brisbane Australia.
I did have one rainy day back in the middle of Winter that was 16% but that will end up being literally the worst day of the year.
To be fair Australia is very sunny. https://en.wikipedia.org/wiki/Solar_irradiance
It also has relatively wealthy people, living in lots of individual housing units. If you wanted to design a country that's perfect for rooftop solar your imagination might come up with Australia.
That said, Australia ought to be able to run almost everything off solar given how sunny it is, and instead solar is a distant second behind coal for electricity production. So there's plenty of work left to do.
