China is has most of its population further south than either USA or Europe. Solar makes much more sense there than in those locations.

Furthermore, by stimulating production of solar and wind related products with domestic consumption, the Chinese state has effectively captured absolute majority share of production across the entire supply chain. This is incredibly useful, when developed countries roll out subsidies for clean power.

Since there are no manufacturers that can match those in China in both price and volume. The bulk of subsidies is used to buy Chinese produced equipment.

At the same time, China is also investing in nuclear technology, and deploying far faster than anywhere in the world.

The world is buying Chinese solar without subsidies. It’s the cheapest power option.

Chinas nuclear share is declining every year.
