That's an insane stat. China added 92GW of solar in May 2025 alone.
Much of this solar was rushed construction to get them in before the new electricity pricing policy goes into effect. It isn't known yet how much the buildout will drop off for the remainder of the year but it is pretty conceivable that some fraction of the construction for the rest of the year was "pulled" forward and rushed to get it in before June. I'm hopeful China's insane buildout will continue but we probably won't see numbers like May 2025 for awhile at least.
The short summary: if a renewable project was built and finished before June, it gets the old, more profitable electricity rates, but if it is finished after June, it is less profitable.

1. it's not a representative month. Building a solar farm for two years and having it go online in one month, leads to big jumps. If you look at the previous year, in 2024 China added 277 GW, so 23 MW per month.
2. At the end of 2024 the US had 239 GW installed. So about the same order of magnitude as China added in 2024 (277 GW, or 15% more).
3. The fact China added in 2024 a similar amount of solar capacity as the US in its entire history, is partly a function of exponential growth in solar in general.
For example Spain doubled its capacity in 2019 versus 2018. Then doubled it again two years later in 2021. Then almost doubled it again two years later in 2022 etc.
In other words it's not so strange in solar actually to see you add in a single year, the same capacity as you've built in all the years prior, regardless of whether it is China. Spain doubled in 1-year period, and then doubled twice in a row in a 2-year period, in the most recent years.
Still it's an insane stat, just wanted to add some nuance. -- The fact we have a president who utters nonsense about wind and solar and is actively working against it, is insane and sad.
