China's polysilicon output will reach 450,000 tons in 2020

        Polysilicon is the basic raw material for the information industry and the solar cell industry. It is refined from metallurgical grade silicon processed by quartz sand and used to manufacture crystalline silicon based cell modules.Polysilicon wafer has some cost advantages over monocrystalline silicon wafer.The silicon link industry has a high threshold. In the past, foreign monopoly was serious. With the success of China's independent technology research and development, it has got rid of import dependence.

        Data show that since 2005, driven by the policy, China's polysilicon industry has experienced overcapacity, elimination of mergers and acquisitions, and the industry concentration ratio has been increasing.The production cost of some advanced enterprises has reached the world's leading level, and most of the product quality is at the level of solar energy level.In 2018, there were 10 enterprises in China with a production capacity of over 100,000 tons of polysilicon, maintaining a high level of capacity utilization with a production capacity of over 250,000 tons.Polysilicon production will reach 342,000 tons in 2019.China's polysilicon production is forecast to reach 450,000 tons by 2020.

        With the rapid development of the domestic market and the continuous expansion of the pv market, China's polysilicon output showed an explosive growth in 2019, with a year-on-year growth of 32% in 2019.

        Future development Trend of polysilicon industry:

(1) The production of polysilicon enters the stage of economies of scale

        Under the joint promotion of the internal and external environment, China's photovoltaic industry technology continues to progress towards the high-end field.In 2018, polysilicon production also entered the stage of economies of scale. The scale of polysilicon enterprises in production is generally over 10,000 tons, and the average comprehensive energy consumption of polysilicon production drops to 80kW · h/kg, and some enterprises even lower than 70kW · h/kg.The average conversion efficiency of ordinary structure polysilicon cells produced by industrial production in China has reached 18.7%, which is the world's leading level.

(2) The production cost of polysilicon has a certain reduction space

        Driven by the progress of production technology, the optimized layout of production and the cost reduction of raw and auxiliary materials, the production cost of components still has a certain space to fall. The total cost of polysilicon is reduced to $6 /kg, the installed cost of the system is reduced to less than 5 yuan/watt, and the cost of photovoltaic per kilowatt is reduced to less than the local price of coal power in some areas.
