In terms of industry scale, the capacity of wind turbines in China in 2010 was nearly 40 million kilowatts, with 18.93 million kilowatts of new installed capacity, and a cumulative installed capacity of 44.73 million kilowatts. All three indicators are in the world. The output of photovoltaic cells in China is 8 million kilowatts, which accounts for half of the world's total.
From the perspective of the completeness of the industry chain, significant progress has been made in the past two years. In the field of wind power, key components such as blades, gearboxes, generators, and control systems have been localized, and product quality has also improved. A complete industrial system integrating raw materials, components, complete machines, and service industries has taken shape. In the field of photovoltaic power generation, the situation in which raw materials are controlled by people has been improved. In 2010, the production of polysilicon exceeded 35,000 tons, and the import ratio fell to 50%. With the continuous release of new production capacity, it is expected that polysilicon will achieve supply and demand balance in 2012.
In terms of technical capabilities, it has already possessed certain independent innovation capabilities. Wind power has realized the conversion of high-power wind turbines from the introduction, digestion, and joint design to independent design. The export of megawatt wind turbines indicates that China's wind power design and manufacturing capabilities have reached international advanced level, and large-scale offshore wind power, direct-drive full power conversion The research and development of new-generation wind power technologies, such as flow technology, are also closely following the world's frontiers. In the field of photovoltaic power generation, Chinese companies have some unique technologies in the production of photovoltaic cells and modules, as well as polysilicon production and waste recycling.
More importantly, the wind power and solar power industry has a number of outstanding companies with considerable scale. In the field of wind power manufacturing, Goldwind and Sinovel have ranked among the top five in the world. In the field of photovoltaic cells and photovoltaic modules, Wuxi Suntech, Tianwei Profit, and JA Solar are among the top 10 in the world. In the field of polysilicon production, Poly Group Xin and Jiangxi Seville will also rank among the top 10 in the world. Most of the above-mentioned enterprises are private enterprises and listed at home and abroad. These companies are most likely to lead the renewable energy industry in China as the next to the communications industry and have the same leadership with the world as Huawei and ZTE Corporation. The advantages of the industry.
