European solar panel makers, led by EU ProSun, filed their second complaint September 25 against Chinese competitors, calling on the European Commission to impose antisubsidy duties on solar panel products from China. Earlier this month, the commission launched a separate antidumping investigation into Chinese solar panel imports after a similar July complaint. The group charged that China only provides subsidies to Chinese solar panel manufacturers, and that more than $35 billion in state aid has led to a production capacity 20 times larger than total domestic consumption and double the global demand. The commission has 45 days to determine whether to launch an official investigation, and if it does, it will have nine months to decide whether to impose provisional antidumping duties, followed by 13 months for European Union member states to decide whether to impose permanent duties.
