Analysts at Roth Capital said confusion regarding China's targeted demand for solar consumption in 2014, along with the ongoing U.S.-China trade war and U.S. suspension of Chinese units of four accounting firms weighed on the solar companies' stocks. Analysts said the U.S. trade officials' investigation into imports of certain solar products from China and Taiwan, and the SEC suspension of accounting firms represent potential near-term industry headwinds.

The investigation could bar import of modules assembled in China into the U.S. market, resulting in higher prices and lower demand. "Not only could this adversely impact Chinese module manufacturers and Taiwanese cell manufacturers, but it could also negatively impact downstream companies in the US and the US market overall," analysts said in a note.
