you would need 200 times the number of solar cells. I don't think you appreciate the scale that 200x is, especially when China is already:

1. quite good at making solar cells

2. quite motivated to increase their energy production via solar

The bottleneck is deploying solar physically, not making the cells.

We have increased the manufacturing of pretty much every piece of technology you see in front you by 200x at some point in history. Often in a matter of years.
