Silicon is incredibly common (sand?), but…solar panels require incredibly PURE silicon. Its a complex process to make a solar panel, but the good news is that they keep coming down in price, which results in more people can afford to add them. Its grown every year.
I believe the US should build a solar panel factory. I know they would cost more than the panels from China, but they could use the latest designs and the latest factory methods. There are lots of city, county, state, and federal installations that can use solar panels so there is a steady market, even if they cost a little more.
Anything that is vital for our future should not be made only in China.
