That is a large reason why I bought US panels and don't have battery back up. Then when it's all done they throw it on a fossil fuel ship for 3000 miles.
There's multiple materials in all panels which are not available in the US due to suppliers exiting the market as a result of operating costs soaring after implementing new regulations.
Being "Made in the USA" often means it's got some domestic glass installed in some US-sourced extrusion (made from foreign raw materials) for the frame.
Hopefully not, but that does tend to be the way 'Made in USA' applies these days, unfortunately.
