Over the past five years, the global production of solar photovoltaic modules has expanded nearly tenfold, with much of that growth captured by Chinese manufacturers. Government subsidies have helped promote the rapid growth, but manufacturers say declining costs will make solar power competitive with other energy sources. China’s share of global solar cell production climbed to almost 48 percent in 2010, up from about 38 percent in 2009. Its rise has come largely at the expense of Japanese and German manufacturers.
