    By the international financial crisis, the global semiconductor and electronics industry slowdown. Among them, the semiconductor industry, annual sales fell by 2.8%, the size of the consumer electronics industry rose by only 0.94%, the growth rate by 5.5 percentage points down. However, the global solar cell industry for five years has continued with high growth momentum, output continued to grow significantly.

    Global solar cell production capacity increased by 83% over 2007, reaching 13GW; solar cell production reached 35% to about 4725MW, PV system, an increase of 35% over the previous yearVGP-BPL8 , VGP-BPL8A ,VGP-BPL9  and reached 3962MW; solar cells market to reach 15.9 billion dollars. In solar cell applications accounted for the 2008 installed capacity of solar cells in Europe for 75% of installed capacity in the world, occupied by Germany, the world’s installed capacity of over 50%. Over the past 15 years, the global PV industry of 25% of the average annual growth rate of rapid growth.

    Solar photovoltaic industry has been able to obtain high growth momentum, thanks in part to clean solar energy as renewable energy, is the world’s new energy development.

    The EU Joint Research Center study shows that will in the future world energy mix, renewable energy, especially solar photovoltaics are an increasing share of solar power by 2030 account for 10% of the global energy mix in 2050 included, this proportion rises to 25% by the year 2100 will reach 64%.

    On the other hand, governments of great importance connected PV industry, and deal with the international financial crisis to cultivate new economic growth point for the important step. Among them, Japan, the recovery of solar energy policy, announced Prime Minister Taro Aso, that by 2020 the amount of solar energy generation, Japan is 20 times higher than the current expansion would be. Obama’s New Energy of the U.S. government will boost the U.S. economy as the most important starting point, wants 150 billion U.S. dollars over the next ten years to invest new energy research. The Australian government announced in May 2009, to spend 1.05 billion U.S. dollars to build the world’s largest solar power plant, estimated that the project could be 1000MWp powered future. In 2020, the Australian renewable energy will supply up to 20% of the total electricity supply.

    Currently, China is the world’s largest manufacturer of solar PV has 11 overseas listed company in 2008, the production of photovoltaic cells tablets 1.78GW, ranks first in the world, accounts for 26% of world production.

    However, with the largest manufacturers of solar cells is in sharp contrast, in 2008, is China’s solar photovoltaic capacity is only 34mW, the world’s total installed capacity of only 0.57% of the national total installed capacity of the calendar year, 140mW, are not sufficient Spain 2008 annual installed capacity of 2511MW by 5.58%. In addition, the production and the huge gap between demand, combined with a lack of core technology is the industry but also in China’s solar photovoltaic industry has led to high external dependence.

    In this context, so that the domestic PV market reached an important development from the corporate level, should step up product development, improve the efficiency of converting solar photovoltaic products, products reduce costs.

    From the perspective of the government, at the time, solar photovoltaic industry in the development of policy in our country’s efforts and the implementation of the scale of VGP-BPL2 ， VGP-BPS2 , VGP-BPS2A ，VGP-BPS2Csubsidies has been further improved, particularly in the electricity price subsidies, tax incentives, demonstration projects in areas such as politics was further strengthened. In March this year progress report of the Ministry of Finance, Housing and Urban-rural Construction jointly published the “solar applications in architecture, policies for financial assistance to fund management, financial support for the implementation of optical construction applications to demonstration Projects address the building integration of solar photovoltaic design and construction features support insufficient application of technical standards, the lack of implementation of components and construction of solar PV module production capacity of weak and so forth to the field of solar initiated photovoltaic applications in rural and urban construction-related markets and lead the development of solar photovoltaic industry

Polysilicon is the world’s largest solar cell materials, although China has the world’s largest solar cell producer, but a long time, polysilicon rely heavily on high-priced imported from abroad in order to earn the domestic producers of solar cells for only a small processing fee.

Recent years, with LDK Solar, Sichuan Xinguang a number of companies such as the introduction of foreign technology have polysilicon project self-sufficiency rate of polysilicon in China PA3534U-1BRS ， PA3591U-1BRS ， PA3465U-1BRS started to improve raw materials. However, because of the technology and process control is not yet in force, China’s polysilicon production costs of high energy consumption, and China, the solar photovoltaic industry in the development of a “flawed”, it seems more step by step, China’s polysilicon industry, face “destruction” of keeping dangerous.

Single-conditioning power consumption corresponds Nanchang 1 / 4

In the current domestic production of polysilicon, the company behind AP K LDK PV Silicon Technology Co., Ltd. are in polysilicon production, as an investment “big ticket” items, from the information already available to the public view, 1, 5 million tons of design capacity is currently the largest single-plant capacity.

This massive project will be located in Xinyu City, Jiangxi Province, Jinan International Photovoltaic Science and Technology Development Zone, base covers an area of 1.162 million square meters of annual production of 3,000 tonnes in the five electronic-grade polysilicon production line, the popular use of the current international “law improve Siemens’ production of polysilicon materials. Project in September 2007 the work started in 2009, began trial operation for the production in the second half.

Polysilicon production with high energy consumption, of which the largest portion of electricity consumption. According to the Jiangxi Provincial Environmental Protection Office Savi 15,000 tons of polysilicon production project be approved, “the project go into production, annual consumption of diesel is about 209,000 tonnes a year of two months from 3.2 billion kWh of electricity,” Single - system power consumption corresponds to the total electricity consumption in Nanchang 1 / 4; is the view of the living plant, the production of the comprehensive energy consumption per kilogram of polysilicon to 213 kWh.

Giant energy like this, a number of SMEs in the manufacturing of polysilicon on the higher energy consumption. Shijiazhuang Dongming Silicon Technology Co., Ltd. in December last year, a polysilicon production in store, with an annual production of 200 tonnes. According to the company office, said Zhang Xin, director of investment banking is a leather company, see above all to earn the industry money, they have an economic activity of Luoyang, Henan province, Siemens France improved technology, which in July started last year, day and night to catch the progress of less than half of the production. At present, 18 tons of polysilicon production business monthly power consumption 3.5 million yuan to 0.5 yuan per kilowatt per month 7 million kWh consumption, production and energy consumption per kilogram of polysilicon to 389 kWh.

All energy recovery two to three years

Such a high energy consumption means that the development of this industry should be restricted to prevent the development? In fact, the same high energy consuming industries, and China’s iron and steel, electrolytic aluminum, compared the two industries, the production of polysilicon, energy consumption per unit output value is less than steel and aluminum.

CPPCC member and president of Nanchang University School of Photovoltaic-week long has been done specifically measured, although the production of energy consumption per ton of polysilicon as steel and aluminum, but much higher than the price of polysilicon per ton of steel and electrolyte - aluminum, even if the polysilicon prices from a peak of $ 400 per kilogram, now stands at about $ 70 dropped to the level of polysilicon energy consumption per unit output value is still lower than the steel and aluminum.

Calculated from the production of polysilicon for the solar industry PV modules power generation, power consumption of the entire process, according to Suntech Power Control Co., Ltd., and Professor Zhou Long, the medium-light conditions in our area, install a one megawatt of solar - volt system, the annual electricity output of approximately 120 million kilowatt hours and 1-watt of silicon solar cells in accordance with an integrated power generation of 3 kwh basis, the 1-megawatt solar photovoltaic system, production installation of three million kwh is installed, only 2.5 years to be fully recovered balance on their own. Since each level of the difference in energy companies, domestic polysilicon solar photovoltaic system, the average payback period of the production installation of energy between the two to three years. With lower energy consumption, the payback period will be reduced further.

At the time when the domestic production of solar energy components of the life span of approximately 25 years, calculated to produce the solar component in achieving the production of energy needed to again, not nearly to consume electricity to some 22 years in power and there are no emissions. In fact, even 25 years later, the efficiency of the solar panels generate about 25 years ago are used to 80%, still for a long time. ZHOU Lang said: “Our country has reduced the commitment of the international community to the year 2020 carbon dioxide emissions per unit of GDP in 2005, 40%, compared with -45%, non-fossil energy accounts for the share of primary energy consumption by 15% . rung In those achieved after the wind electricity, nuclear power, is following the great development of photovoltaic power generation in early development. ”

Save Imperative

Although recovery can cycle perspective polycrystalline silicon solar cell module is used to restore production of electricity in 2023. However, as China’s polysilicon production unit energy consumption is much higher than the world advanced level, which is also our production capacities for polysilicon costs farPA3399U-1BRS ， PA3399U-2BAS ， PA3399U-2BRS ， PA3421U-1BRS higher than the world advanced level, once the world’s advanced level on behalf of seven main groups of foreign collective price reduction our existing production capacities for polysilicon companies will face huge losses, is China’s polysilicon industry, the danger of destruction.

Zhou Long explained that currently produces overseas, seven major polysilicon manufacturers a comprehensive energy consumption per kilogram of polysilicon 120 kWh kWh between -150 and our average level of polysilicon production company more than 200 kwh, and many small factories and also the level of more than 300 kWh. The polysilicon production costs, power consumption currently is the most important part of China’s advanced polysilicon production at its state of high energy consumption, making domestic polysilicon production costs far higher than the world level.

Opto-Electronic Technology Co., Ltd. Sun, general manager of Jiangxi Peng said that currently on the international market price of $ 60 to $ -70 polysilicon, the domestic enterprises to produce a kilogram of polysilicon costs of -50 Dollar 40 dollars more in between, and Overseas seven major polysilicon, the cost of manufacturing firms $ 20 $ -30. After the seven major groups of foreign collective lower prices is China’s polysilicon production companies are facing bankruptcy.

The polysilicon industry is capital-intensive industries, a huge investment, higher corporate assets and liabilities. In LDK Solar LDK Solar Silicon Technology Co., Ltd. 15 thousand tons annual production of polysilicon project, for example a total investment of more than 10.0 billion euros, of which only the more than 100 million yuan investment in environmental protection. From the reporter who interviewed a number of PV companies responsible for comprehensive assessments, polysilicon industry average asset-liability ratio of more than 60% when a company is bankrupt, the banks bear the huge loan losses.

For the high energy consumption of China’s polysilicon industry, the industry there is a crisis of the status quo, Zhou Long, Peng and other professionals who suggested that the government measures to encourage enterprises, research institutes, as polysilicon to reduce production and consumption take a joint scientific research and the company revenues should be a higher proportion of R & D costs extract to go into production and reducing consumption of technical research and technological improvements.
