The New York Times reports that seven U.S. solar panel manufacturers have filed a broad trade case at the Commerce Department in Washington against the Chinese solar industry, accusing it of using billions of dollars in government subsidies to help gain sales in the American market. The companies also accused China of dumping solar panels in the United States for less than it costs to manufacture and ship them, according to the report.

The U.S. companies seek tariffs of more than 100 percent of the wholesale price of solar panels from China. The case is being led by Oregon-based panel maker SolarWorld Industries America. The six other companies that joined the case chose to remain anonymous under Commerce Department rules, fearing reprisals from the Chinese government.
