We have a solar cell plant in the middle of our state ,Moses Lake, WA, It makes solar cells and silicon that it exports. My company picks it up sometimes (400 mile round trip) and take it to the airport to send to china.
My state also has a huge subsidy if a solar cell and inverter is manufactured in this state.
I talked to a local solar panel installer company. He told me that solar cells are a commodity that is easy available from many sources. He also said he tried to talk to the Moses Lake company to make panels for him but they weren't interested in small change.
It is a sign of colonialism when you ship raw materials to another country and buy it back as finished goods.
