This was true a couple of years ago.

This is no longer true.

Storage has become a lot cheaper very rapidly. The LCOE of solar with storage covering the night is now competitive.

Not entirely sure: everywhere I read about solar + storage, there are huge errors bars. Eg : https://www.lazard.com/media/eijnqja3/lazards-lcoeplus-june-...

Solar+storage : from 50$/MWh to... 131$/MWh !

Go make a decision with something like that.

The trend is clear, for sure, and it will make sense to extrapolate... Up to a point, as usual. (baring one of the "breakthroughs" that make it to the HN top page on e in a while and never materialize... Sigh)

Night, sure. Doesn't work in winter though. (Not that that means we should stop building solar - we're still far from the point where it wouldn't make sense to build any more solar because we can't store the energy.)

  • If you're bordering on the article circle, yes. Otherwise you just have to overbuild a bit more.

    • I live in the UK. The ratio between solar output on a typically sunny summer day and a typical cloudy winter day is about 20. So your "a bit" is doing a hell of a lot of work there.
