That doesn't significantly change the argument. Most solar plants have capacity factors of around 20% (5% might apply to home systems, but not commerical), compared to nuclear which has around 80%. So a factor of 4. So numbers change a bit on the previous poster, China just installed 3x more solar in 1 year than all the nuclear under construction, or they essentially installed the same amout of solar in one year as all existing and under construction nuclear combined. And if we look at projections, next year they likely will install twice as much solar...

While China is often put up as the poster child for nuclear power, they are actually a great example of how nuclear is being overtaken by renewables. China's 2019 plan was that by 2035 nuclear would account for ~8% of generated electricity (up from ~5%). Since then percentage dropped to 4.5% (and the drop seems to be accelerating). Unless something dramatically changes nuclear will account for less than 4% (not the planned 8%) of generated electricity by 2035. All that is due to the raise of renewables (largely solar). I suspect we will not see China build close to those projected 200 GW and the percentage to be even lower, just due to the exponential growth in solar.

Yes yes, one of the usual reflexive context free points repeated every time solar comes up. Whatever the actual capacity factor is(5% is not a serious number ), I’m sure chinas energy planners know that, it’s hardly a gotcha. And still they’ve choose to build solar at a volume massively dwarfing nuclear
