Aside overcapacity should be synonymous of low prices, I still wait to see here in EU prices like in the BRICS area for products imported from China. An example a BYD Atto 3 here cost a bit less than 40k€ while in Thailand cost a bit less than 10k€ https://asia.nikkei.com/content/1f9ed40b4b44745e1a39fafaf94b... such price delta have no justification in mere free market economical terms, have only political justifications NONE OF THEM acceptable by the civil society. I still wait to see LFP batteries prices drops like in China to have a well-sized home battery at a price cheap enough to make buying it convenient, let's say 50kWh for 5k€. Let's say 15kW p.v. inverter for 1.5k€ etc.
If China manufacturers goes broke we customers do the same in EU, and I suspect in USA to, simply to enrich some local cleptocrats.
