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.
- phtrivier 1y agoNot entirely sure: everywhere I read about solar + storage, there are huge errors bars. Eg : https://www.lazard.com/media/eijnqja3/lazards-lcoeplus-june-2025.pdf 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)
- IshKebab 1y agoNight, 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.)
- gpm 1y agoIf you're bordering on the article circle, yes. Otherwise you just have to overbuild a bit more.
- IshKebab 1y agoI 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.
- nasmorn 1y agoGlobally seen the Uk is close to the arctic circle. It is one of the worst cases
- IshKebab 1y agoRight but it's not exactly the latitude that's the issue. On sunny days in winter I get plenty of power. The issue is the weather - only about 1/3 of the days in winter are sunny.
- gpm 1y agoYeah, my comment was a simplification - like most things trying to describe local effects globally are. The UK doubles as unusually cloudy weather and relatively short days.
