JinkoSolar (NYSE:JKS) shocked investors by posting a second quarter profit on the back of a growing systems business and 17.7% gross margins. Canadian Solar (NASDAQ:CSIQ) and Trina Solar (NYSE:TSL) are also getting closer to a profit but with larger debt loads they'll have more challenges than JinkoSolar did. Still, the Chinese solar industry is starting to get closer to profitability and the strongest balance sheets are leading the way.
