The European Union plans to rebuild its solar panel industry by manufacturing in the home country. This means shifting away from supply channels where China controls 80% of production. Chancellor Merkel failed to see the risks of letting German companies be decimated by China's subsidy program supporting solar panel makers in China. A system of customs duties failed when China threatened to retaliate with duties on German car exports. In the end Germany like the US under president Obama and Trump after 2010 failed to support domestic solar panel makers. Now subsidies are accepted way of competing with China for both the US and the EU. The US under the Biden administration is fully committed to compete with China by developing its own solar panel manufacturing industry with the kind of help China is giving to its own solar panel makers. The EU is following the same path. From 200 gigawatts in 2023 the EU's target is 600 gigawatts from solar by 2030. The 400 gigawatts will come from through a policy of make at home in the EU, including raw materials, polysilicon, wafers, and assembly. Subsidies are now the way the US and the EU plan to get back what they lost to China, their critical manufacturing advantage through errors in policy. The European Commission is also changing the rules to accomodate the move. A story of one more critical advantage surrendered through the orthodoxy of free markets without policymakers understanding what they were doing. ...
