On top of that, the consumers cannot resolve overcapacity in industrial goods. China has 1000GW of solar manufacturing capacity, and their peak hourly demand is less than 1200GWh. If they installed new 1000GW of solar panels, a big bulk of the production would simply go to waste.

Then we can take a look at their battery production capacity. They are going to hit 6TWh or 6000GWh production capacity soon. Assuming each EV on average has a 60KWh battery, they have sufficient capacity to equip 100mil EVs each year and the global car sales annually is only around 70mil to 80mil. Other parts of the world still have 2TWh production capacity.

Many other industries like steel-making or construction-related industries are also operating below peak capacity. If you are one of those who think China anyhow throw money into fanciful infrastructure and that there are excess houses already, then the only solution is to downsize them rather than prop them up artificially to build things that are not necessary. Perhaps they should only restart and carry on building those houses which people already paid money for and then spend money to upgrade or refurbish existing homes like our HDB upgrading. But massive resources should not be going into those sectors already.
For their EV capacity, they are closing in on the 36 mil capacity mark, and that does not include their older ICE vehicle capacity. 36mil EV production capacity vs 70mil new car global demand annually (EV + ICE).

Hence, consumer spending alone cannot resolve overcapacity in those high-value and industrial goods segments. If we dig deeper and expand to more industries, many will probably face the same problem.
