JA Solar does not warm to the proposition that all clouds have a silver lining. The company manufactures monocrystalline and polycrystalline solar cells that are incorporated into photovoltaic modules and conversion systems, which turn sunlight into electricity. The company sells its components directly to photovoltaic system manufacturers in Canada, China, Germany, and the US. Top customers include Canadian Solar, Jiangsu Aide Solar Energy, Shanghai Chaori, Shanghai Solar Energy, and Wuxi Jiacheng. JA Solar gets about three-quarters of its sales in China.
