Major polysilicon solar cells in the world of commodities, even if China became the world’s largest producer of solar cells, but a long period of polycrystalline silicon heavily dependent on high cost imported from abroad, manufacturers of household solar cells to earn only modest processing fee.

Recent years, with LDK Solar, Sichuan Xinguang a number of companies such as the introduction of foreign technology, have launched the polysilicon, self-sufficient rate of raw material polysilicon China has been improved. However, as technology and process control is not yet in place, costs of production of polysilicon in China of high energy consumption and has become the solar photovoltaic industry in China in the development of ‘a “flawed”, appears stronger step by step to maintain the polycrystalline silicon industry in China, facing the “destruction” of the dangerous.
Single-energy plant in Nanchang equals 1 / 4
In the current domestic production of polycrystalline silicon business to come from behind K LD LDK PV Silicon Technology Co., Ltd in the production of polycrystalline silicon, investment called “big ticket” items, the information already made public view, 1 .5 million tons of nominal capacity is currently the largest single plant capacity.

This major project is located in Xinyu City, Jiangxi Province, Jinan International Development and Science based photovoltaic technology, covers an area of 1.162 million square meters, annual production of 3,000 tonnes of five electronic online production of quality polysilicon comprising the popular use of international news “improved Siemens Law” producing polycrystalline silicon materials. Project in September 2007 began the construction of the second half of the production process in 2009.
The production of polycrystalline silicon with high energy consumption, including most of the power consumption. According to Jiangxi Provincial Environmental Protection Bureau Savi produce 15,000 tons of polysilicon project approved, the project is put into production, annual consumption of diesel is about 209,000 tons, the annual two months of 3.2 billion kWh of electricity, only the consumption power plant is equivalent to the total electricity consumption in Nanchang 1 / 4 ’s, does not plant the living energy, the production of consumption total energy per kilogram of polysilicon to 213 kWh.

Energy giant as a number of SMEs in the production of polycrystalline silicon on the higher energy consumption. Shijiazhuang Dongming Silicon Technology Co., Ltd. in December last year, the production company of polysilicon, the annual production of 200 tonnes. According to the office of the society, said Zhang Xin, director of the investment firm is a company of leather, mainly to see the industry make money, they buy a company of Luoyang, Henan province Siemens France improved technology, began in July last year, day and night to catch up with advances in less than half of production. Currently, companies producing polysilicon 18 tons per month, the electricity consumption of 3.5 million yuan to 0.5 yuan per kilowatt per month, 7 million kWh of consumption, production and energy consumption per kilogram of polysilicon to 389 kWh.
All energy recovery two to three years
Such high energy consumption, make the development of this industry should be limited to even prohibit development? In fact, the same high energy-consuming industries and China’s iron and steel, electrolytic aluminum, has compared the two industries, the production of polycrystalline silicon for the energy consumption per unit output value is lower than steel and aluminum.

CPPCC member and president of Nanchang University School of weeks photovoltaic Lang has been specifically measured, despite the production of energy consumption per ton of polysilicon as steel and aluminum, but much higher than the price of polysilicon per tonne of steel and electrolytic aluminum, even if the price of polysilicon from a peak of U.S. $ 400 per kilogram has fallen to its current level of about $ 70 U.S., consumption energy per unit of polysilicon output value is always less than steel and aluminum.
From polycrystalline silicon for solar photovoltaic modules produce electricity, the power consumption of the whole process, according to control Suntech Power Co., Ltd., and Professor Zhou Lang has calculated that the average light conditions in our region, the installation of one megawatt solar power system V, the annual production of approximately 120 million kilowatt hours, and 1 watt of silicon solar cell integrated power system production facility 3 kwh under the terms of megawatts of solar photovoltaic power generation system was installed to produce three million kwh, only 2.5 years can be recovered balance its own power. As each level of the difference in energy companies, domestic solar polycrystalline silicon photovoltaic power generation system, the average payback period for installation of energy between two to three years. With low energy consumption, the payback period will be further reduced. ThinkPad R50 battery ThinkPad R51 battery
Currently, domestic production of solar modules around the life of 25 years, as calculated to produce the solar component in achieving the production of recovered energy, almost need to consume more electricity can power about 22 years, and there are no emissions. In fact, even 25 years later, the efficiency of solar module production there about 25 years to 80% may still be used for a long period of time. ZHOU Lang said: “Our country has the will of the international community in 2020 emissions of carbon dioxide per unit of GDP in 2005 dropped by 40% compared to -45%, non-accounts of the fossil energy for the proportion of primary energy consumption has reached about 15%. Among these, after the wind electricity from nuclear power after the general development of the production of photovoltaic solar energy will open at spring development. ”
Saving Imperative
Although the view recovery cycle, production of polycrystalline silicon solar cell module of electricity consumed can be recovered in 2023. However, China’s production of polycrystalline silicon consumption per unit of energy is much higher than the world advanced level, which is also our polysilicon production costs are much higher than the world advanced level, once the world’s highest level for the seven main groups of price reductions abroad collective, our existing production of polysilicon companies will face huge losses, the industry polysilicon China, there will be danger of destruction.

Zhou Lang explained that at present abroad, seven manufacturers of major producers of polysilicon overall consumption of energy per kilogram of polysilicon -150 kWh 120 kWh between the two, and our average level of business manufacture of polysilicon over 200 kWh, and many small factories and even the level of more than 300 billion kwh. Production costs of polysilicon, the energy is precisely the most important, China’s production status of polysilicon high energy consumption, resulting in production of polycrystalline silicon internal costs are much higher than in the world advanced level.
Photoelectric Technology Co., Ltd. Sun, general manager of Jiangxi Peng said, at present, the international market price of U.S. $ 60 on the polysilicon -70 U.S. dollars, local businesses to produce a pound of silicon cost polycrystalline -50 U.S. $ 40 dollars more in between, overseas and seven major polysilicon cost of manufacturing firms U.S. $ 20 -30 dollars. Once the seven major groups of overseas prices lower collective enterprises producing polycrystalline silicon in China will face bankruptcy. Aspire 3000 battery LCBTP03003
In addition, the polysilicon industry, are capital-intensive industries, a huge investment, higher rates of corporate assets and liabilities. For LDK Solar LDK Solar Co., Ltd. silicon technology projects a yearly production of 15,000 tonnes of polysilicon, for example, total investment of over 10.0 billion euros, with investment of just over 100 million yuan in environmental protection. From the journalist who interviewed a number of companies photovoltaic comprehensive estimates of the polycrystalline silicon industry assets-liabilities ratio averaged over 60%, once a bankrupt company, the banks will bear the losses enormous loan.
For the high energy of the polycrystalline silicon industry in China, the industry there is a crisis of the status quo, Zhou Long, Peng professionals in these proposals, the state should take measures to encourage businesses, research institutes, such as the production of polysilicon and reduce the consumption of a joint scientific research and encourage enterprises from sales revenue to extract a greater proportion of R & D spending, set production and reducing consumption of technical and technological improvements. 402018-001 371790-001
