Last year, China generated 834 terawatt-hours of solar power.
Which is more than the G7 countries generated, and more than the US and EU combined. In fact the only country group that generates more solar power than China is the OECD, all 38 countries of it.

OP sepcifically mentioned EVs. This sector is deflationary even in US, where better value/performance cars cost less every year. More dramatic deflation in less corrupt countries. Australia home solar costs under 1/3rd of US due to different politico-social corruption levels.
EVs and home solar are a great match that permits going offgrid at substantially lower cost if an EV is parked at home during day. That same dynamic allows a society/community to power itself through solar+batteries, and EVs parked at work. It’s not a question of look at our corrupt obstructionist oligarchical monopoly state of societies for examples of lack of economic success as proof that it will forever be impossible.
EVs are rare (in the context of total energy consumption, even more so because not so many models offer this feature), limited to houses (what do you do when you live in a flat?) and not a reliable source - “honey, I need to drive fetch some groceries, you won’t have energy in meantime”. How many houses with only EVs as energy storage are disconnected from grid? I bet the number is next to 0. OTOH EVs as energy storage can provide buffering to energy grid when properly connected. This feature has its place, but they can’t be used for reliable storage.
