Consolidation in China’s solar manufacturing industry will accelerate in the next three years, driven by falling technology costs and a 20-25% annual increase in solar installations across the industry, Bloomberg reported, citing Trina Solar (TSL.NYSE) Chairman Jifan Gao. Gao said he expects three to five “leading” solar companies to remain in China by 2017, with 80% of the country’s market share. The Changzhou, China-based company posted a profit in the third quarter, and its shares have more than tripled since November.
