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.

They pay the windfarms when too much power is generated for the grid to handle. The wind turbines are then throttled accordingly and the windfarm owners are reimbursed for the lost potential. At least that’s how it goes in Germany. It’s kind of an incentive to upgrade the power grid.
