Having those US solar manufacturing plants buy materials in the US and machinery made in the US creates more US jobs.
Do you know how few jobs a solar panel factory produces? It's on the order of a few thousand.
If you want a LOT more jobs, you need to make sure solar panels are as cheap as possible in order for more to be installed, which is where the labor costs will be.
If China can make cheaper solar panels, LET THEM.

That's a short term win long term loss attitude. China then becomes the R&D center for the next gen energy equipment. That's not in the best long term interest of the US.
