The value of China's solar exports fell by almost one-third in the first half of 2013 as trade disputes took a toll on prices, an industry group said on Friday.

According to the Photovoltaic Product Branch of the China Chamber of Commerce for the Import and Export of Machinery and Electronic Products, the value of solar cell and module exports plunged 31 percent year-on-year to $6.5 billion in the first six months.

Prices were down 41 percent, while export volume increased 17 percent, the organization said on its website on Friday.
