Polysilicon "loose" to promote photovoltaic applications
A few days ago, after the three ministries and commissions issued the "Plastic Industry Access Conditions" at the end of last year, the Ministry of Industry and Information Technology began to apply for industry access in the form of notice. According to the requirements of the Notice, local industrial and information administration departments are responsible for accepting polysilicon enterprises in the region. Admit the application for the announcement and report the verification opinion and the company's report materials. The Ministry of Industry and Information Technology will, after organizing experts and entrusting the relevant testing institutions to review and inspect the application materials, will issue a list of polysilicon enterprises that meet the entry requirements in the form of announcements with the relevant ministries. The industry generally believes that the release of this "Notice" is an important signal that China's polysilicon project approval will "open the gate", but also prepares conditions for the domestic start of the photovoltaic application market. It is understood that polysilicon products are regarded as the foundation of microelectronics and photovoltaic industry. It is a technology-intensive product, which is widely used in high-tech products in the fields of chemical, metallurgy, machinery, electronics, etc., and was the main raw material of semiconductor in the early stage. Nowadays, it has become an important basic raw material for large-scale integrated circuits and solar cell industry. The polysilicon industry has developed rapidly in the past few years in China. However, at the end of September 2009, due to the State Council’s persistent suppression of over-construction and repeated construction of documents (commonly known as Circular 38 in the industry), the industry’s development has stagnated and has been “overcapacityâ€. And "high pollution" hats. In fact, after more than a year of market changes, the arguments of high pollution and overcapacity in the past still need to be discussed. According to the survey conducted by the Ministry of Industry and Information Technology, polysilicon production itself is not a highly polluting industry. However, if the recycling production and the comprehensive utilization of by-products are not completed in the production process, it is highly likely to cause environmental pollution. According to experts' interpretation, in the production process, polysilicon will produce a by-product called silicon tetrachloride, which will cause environmental pollution. Because of its high recycling cost, many small and medium-sized enterprises will not be able to recycle at all. . However, for large and regular production enterprises, zero-emissions can be achieved if fully enclosed management is achieved. At the same time, according to relevant data from the General Administration of Customs, the amount of imported polysilicon in China reached 21,000 tons in 2009, accounting for 55% of total domestic demand. In 2010, the monthly growth rate was above 100%. As of October last year, The number submitted has exceeded 30,000 tons. There are currently 370 PV companies in China, while there are only 80 polysilicon companies. In 2010, although China's polysilicon production accounted for 18% of the world's share, it could not meet domestic product demand. Due to the influence of "No. 38 Document", many small and medium-sized enterprises have stopped production and are even on the verge of bankruptcy. Under the combined influence, while the development of some domestic enterprises was blocked, the domestic polysilicon prices were continuously pushed up. The most important thing was that the imbalance between domestic supply and demand led to dependence on imports, which benefited international manufacturers. Using a corporate executive's words to evaluate the domestic industry situation is that enterprises and investors look at a good market, guarding empty factories and unopened equipment to cry, watching foreign giants earn a lot of money. Indeed, there have been estimates before that the market suffered from domestic losses of more than 100 billion yuan due to the “No. 38 Documentâ€. This year, the demand for polysilicon is still below 100,000 tons. With the introduction of the entry standards at the end of last year and the application for a recent entry, the industry believes that the domestic polysilicon project will re-emerge, and the "No. 38 text" may also be lifted. The reporter learned from the access conditions that the polysilicon project for the new project requires that the scale of the solar-scale project should be greater than 3,000 tons per year, and the size of the semiconductor-level project should be greater than 1,000 tons per year. For solar-grade projects, the overall energy consumption must be less than 200 kWh per kilogram. In terms of environmental protection, in addition to the water recycling rate ≥95%, in terms of wastewater, waste gas, solid waste, noise, etc., it must also meet the corresponding environmental standards. According to industry insiders who have participated in the formulation of access standards, at present, only 25% of the domestic 50 companies can reach the production capacity standard. Even if the projects have been filed and are ready to be built, half of the projects will be compared with the access standards. Unable to approve. The reporter found that based on the deliberate blockade of foreign polysilicon production technology in China over the years, most small and medium-sized enterprises in China have not met the entry requirements for hardware equipment. The number of companies may be limited, and there is a contradiction with the market demand. According to 2010 data, based on the rapid growth of the global photovoltaic industry, the demand for polysilicon production in the year was raised, which led to a global production of 160,000 tons, an increase of 52% over 2009. In the top 5 of the production enterprises, China's largest producer, Poly GCL, was short-listed, but only ranked third, and the crown and runner-up were occupied by German and American companies. The total output of the top five companies accounted for 60% of the total global production. From the perspective of the global photovoltaic industry, in the middle and late May, the Swiss and German governments have publicly stated that they will reduce domestic nuclear power generation, and even give a timetable for “abandoning the nuclearâ€, although analysts believe that the “statement†of this statement is higher than actual. Operation, but also indirectly illustrates the development trend of renewable energy industry such as global photovoltaic. From the "No. 38 Document" to the initiation of the project application and approval work in China, it is not difficult to see that in a short period of one and a half years, such a rapid change has clearly demonstrated that the country integrates the polysilicon industry, supports the development of the photovoltaic industry, and practices environmental protection. The comprehensive regulation of the concept of energy conservation. As Meng Xianyu, vice chairman of the China Renewable Energy Society, said, this means that China's PV industry will enter a healthy and orderly development track, which will help large-scale polysilicon backbone manufacturing enterprises to become bigger and stronger.
