(1) China has become a big power production and application of ductile iron pipe In 2009, the country's polysilicon production has reached 1.8 million tons to 2 million tons, the formation of 15 to 20 million tons of production capacity. In 2009, China's solar cell production capacity exceeded 3,200 megawatts, ductile iron pipe component output of about 2500MW, the global account for 3 percent or so. China's Suntech, JA, Tianwei Yingli, and other enterprises have entered the world top ten. In 2009, with the introduction of ductile iron pipe stimulus, installed in 2009 will exceed 20 million kilowatts, an increase of the size installed more than 200% over the past few decades the total cumulative installed capacity, the global market share by 2008, ductile iron pipe of 0.8% to 2.7%, and the first among the world top ten ductile iron pipe market. (2) excess production capacity of polysilicon, the industry reshuffle imminent As of 2009, concentrated around the release of new polysilicon production capacity, excess supply and gradually obvious. Currently, the domestic spot price of polysilicon has been $ 500 last year to drop to 50 to 60 kg of dollars. Polysilicon capacity expansion too fast, and relatively slow growth in demand is the main factor leading to price decline. Currently, the domestic high-end polysilicon production equipment essential to rely on foreign imports, high technology transfer fees and equipment purchase costs of our polysilicon production costs. Short term, the domestic polysilicon plants under construction have been hit the most, these investments may not generate huge benefits that a heavy burden investors. In 2009, the era of polysilicon profits inflection point. (3), ductile iron pipe in all sectors of the industry chain, China is stronger than in the upper reaches of the advantages of lower Overall, the majority of domestic enterprises is located in the back-end into the solar cell and module production processes, and the main raw materials, production technology of crystalline silicon, now firmly in the United States, Japan, Germany and a few hands of the state. View from all sectors of the industry chain, polysilicon links in our country does not have a clear competitive advantage, China has cast and the dozens of polysilicon plant construction, the majority of Siemens improved technology, some of China has not yet mastered the key technology in the refining more than 70% during all of polysilicon by chlorine gas emissions, not only the high cost of refining, and environmental pollution is very serious. Downstream battery packaging industry, the development of China's most mature production technology, equipment localization rate the highest, the fastest expansion, the largest output, is a part of the largest corporate practitioners, can be more obvious advantages. (4) competition becomes more intense, ductile iron pipe industry consolidation will occur Due to intense competition, product prices decline accelerated from 2009 the supply will exceed demand, component manufacturers will be the first wave of reshuffle, especially those producing cells also produce components maker, will cut prices ahead. Decline in value of products in 2009 will drive the industry consolidation, smaller companies will be acquired or closed down, while the surviving company, will also face excess supply caused by pressure on margins. With low-cost thin-film battery technology businesses, the ability to decline in value against the product will be superior to other enterprises. .
