The 1.26 tons/year polysilicon project undertaken by Guangxin Silicon Industry is the largest polysilicon production project in China at present, with an estimated total investment of about 1.29 billion yuan. From the successful commissioning at the end of February 2007 to the end of September 2007, the company produced about 69 tons of polysilicon, and plans to produce 200 tons in 2007.

4. Leshan Electric Power (600644) invested 255 million yuan (accounting for 5 1% of the shares) to jointly establish Ledian Tianwei Silicon Industry Company with Tianwei Baodian Company to build and operate Leshan 3000-ton/year polysilicon project. The total investment of the project is estimated to be about 2.2 billion yuan. The investment period is expected to be two years, and it will be put into production in the third year. In the fourth year, the production load reaches 80% of the design capacity, and in the fifth year and beyond, the production load is 65,438+000%. ?

5. Minjiang Hydropower (600 13 1) invested in Tianwei Sichuan Silicon Industry Co., Ltd.13.23 million yuan (accounting for 14%) to invest in Xinjin 3000 tons/year polysilicon project. The total investment of Xinjin 3000t/a polysilicon project is 2.675 billion yuan. The total investment of the project is about 2.7 billion yuan, and the company's contribution ratio is 14%. The construction period of the project is 2 years, and the designed production capacity will be reached in the fifth year. ?

6.CSG A (0000 12) signed an investment project of polysilicon materials and solar cells with a total investment of 6 billion yuan in Hong Kong in June 2006, and invested in the construction of two high-purity polysilicon materials and solar cells industries in Yichang, Hubei, with an annual output of 5,000 tons of high-purity polysilicon and 450 MW of solar cells. ?

7. Shanghai Solar Energy Science and Technology Co., Ltd. (70%), a holding subsidiary of Aerospace Electromechanical Co., Ltd. (600 15 1), is the largest research, development, production and sales company of solar energy products in China, with the output reaching 10 MW for the first time, which is equivalent to more than 50% of the total solar energy production capacity in China. Shenzhou New Energy, a wholly-owned subsidiary of the company, has built a polysilicon production plant of10.5 million tons/year in Inner Mongolia, with a total investment of about 654,380+0.8 billion yuan. ?

8. Jiangsu Sunshine (600220) Company invested a huge sum of money to establish Ningxia Sunshine Silicon Industry Company to produce polysilicon, accounting for 65% of the company's shares. Polycrystalline silicon is the direct raw material for producing monocrystalline silicon, and it is the basic electronic information material for contemporary semiconductor devices such as artificial intelligence, automatic control and information processing. Known as the cornerstone of microelectronic architecture, the most important thing is that polysilicon is the core raw material of solar energy. At present, domestic polysilicon basically depends on imports, but due to technology monopoly, the company's development prospects are very promising.

The company's newly established subsidiary will produce 4000 tons of polysilicon annually in the future. The project has started and is expected to be completed by the end of this year. In the first phase, the company has an annual output of 65,438+0,000 tons of polysilicon, and newly built 2 * 65,438+0.5 kW self-provided power plant and hydrogen production plant. Once the construction is completed, the company is expected to become the largest polysilicon enterprise in China and even Asia, and become the monopoly leader of solar upstream resources. ?

9.TBEA (600089) TBEA signed a capital contribution agreement with Emei Semiconductor Research Institute, Xinjiang TBEA (Group) Co., Ltd. and Shanghai Honglian Venture Capital Co., Ltd. on June 5438+ 10/8. The above four companies will jointly invest 400 million yuan to set up a polysilicon company. Among them, TBEA contributed 300 million yuan, accounting for 75% of the registered capital of polysilicon company.

After the establishment of polysilicon company, it is planned to invest in the construction of10.5 million tons/year polysilicon project. According to the feasibility analysis report, the investment in fixed assets of this project is 65,438+0,406,865,438+0,000 yuan, and the rest of the funds will be settled by means of bank loans, etc. ?

10, Tuori Xinneng (0022 18) Co., Ltd. is a high-tech enterprise integrating the production and sales of R&D, amorphous silicon, monocrystalline silicon, polycrystalline silicon solar cell chips, solar cell modules and solar cell application products, forming a complete industrial chain from battery chips, battery modules to terminal application products. The main products include solar cell chips, solar cell modules, solar lamps, solar chargers and solar homes. ?

1 1 and Erdos (600295) Company can produce 535,000 tons of ferrosilicon this year, ranking first in the world. In 2008~2009, ferrosilicon products will be the main source of the company's profit growth. Entering the polysilicon industry through the private placement plan will add stamina for the company's development. The company takes advantage of the production of industrial silicon and electric energy to intervene in polysilicon.
