China's wind turbine manufacturing industry became the largest in the world in just four short years, with three Chinese producers now in the top 10 globally, according to the latest BTM report: Sinovel, Goldwind and Dongfang – see page 32 for more details on this. More than 80 domestic manufacturing firms now exist and most Chinese turbines are now in the 1.5–2 MW class, in comparison with earlier years when sub-1 MW models still accounted for a large proportion of turbine production. China is now also the largest manufacturer of solar PV, supplying almost 40% of all solar PV worldwide in 2009. About 4 GW/year of manufacturing capacity existed by the end of 2009 and more than 500 solar PV firms were established. The top-three Chinese producers were Suntech (704 MW in 2009), Baoding Yingli (525 MW), and Jingao (JA) Solar (524 MW).
