Domestic solar panel producers are looking to emerging markets to offset mounting difficulty in the United States, where they fear they may be entirely squeezed out by a new ruling on dumping duties.

A final decision announced on Tuesday by the US Department of Commerce said that solar panel products from the Chinese mainland were sold in the US at dumping margins ranging from 26.71 percent to 165.04 percent, and those from Taiwan were from 11.45 percent to 27.55 percent.

Products from the mainland received government subsidies ranging from 27.64 percent to 49.79 percent, according to the department.
