“Establishment of ecological civilization is a millennium plan for sustainable development of the Chinese nation.†The report of the 19th CPC National Congress raised the construction of ecological civilization to a new height. At the same time, the report of the 19th CPC National Congress pointed out that the revolution in energy production and consumption should be promoted to build cleanliness. Low-carbon, safe and efficient energy system. This series of new arrangements for the development of ecological civilization and new energy has inspired the people throughout the country. In order to develop clean energy, Qinghai Province has been making efforts in recent years, even walking in the forefront of the country and the world. In particular, the industrial development base represented by the Dongchuan Industrial Park in the Xining Economic Development Zone has succeeded in creating a photovoltaic industry chain by continuously exploring a green road for the development of new energy, which has become a unique “scene†for the development of photovoltaics in China. The harmony between man and nature, the Tao of nature, green mountains. This ecological wisdom and simple concept have been accumulated rich philosophical connotations by the five thousand years of civilization in China. Today, the philosophical remarks of the pioneers still have profound enlightenment. The 19th National Congress of the Party pointed out the direction for the construction of ecological civilization and green development in China in the future, and planned the route. Speaking of green development can not but mention clean energy, and this is particularly important in the photovoltaic industry in renewable energy. According to the “Renewable Energy Market Report 2017†issued by the International Energy Agency, the global solar PV production capacity will increase by 50% in 2016, and China will contribute more than half. In the next five years, China will continue to be the undisputed leader in global growth in renewable energy. The development of the photovoltaic industry in Qinghai is even more compelling. Dongchuan Industrial Park in Xining Economic and Technological Development Zone has been moving forward for five years, creating a golden industrial chain for the photovoltaic industry, making Qinghai a leader in the development of the national photovoltaic industry. Shine." Create a photovoltaic clean energy equipment base If you say that the world is the most clean, it is undoubtedly the nearest “roof of the world†from heaven. There is a wealth of solar energy resources and a large-scale desertification land resource advantage, and the development of photovoltaic is unique. It is the purest resource God has given to the purest place. Xining Economic and Technological Development Zone based on the resources of Qinghai Province, relying on solar energy resources in Qinghai Province to develop photovoltaic industry, formed a complete photovoltaic manufacturing industry chain of polysilicon - monocrystalline silicon - slice - solar cell - battery components, gathered the inverter, photovoltaic Glass, quartz crucibles, aluminum frames, supports and other supporting photovoltaic companies. It has become an equipment base for the development of the photovoltaic industry and has provided important equipment support for the photovoltaic industry in Qinghai Province and even the whole country. Many more descriptions are not true with numbers. Up to now, the annual production capacity of polycrystalline silicon in Dongchuan Industrial Park is about 17,500 tons, all of which have reached the national standard of high-efficiency battery usage. The annual production capacity of Chinese standard electronic polysilicon is approximately 10,000 tons, and the annual production capacity of monocrystalline silicon is approximately 7,000.

In early November of this year, the 9th China (Wuxi) International New Energy Conference and Exhibition, known as "Davos" in the field of new energy, countless new energy companies turned their attention to Qinghai. Duan Yuhe, president of Shanghai Electric Co., Ltd., mentioned that the entire industry in Qinghai is currently the largest in the country and has great potential. We want to put good technology into good provinces. To this end, we are actively involved with the Xining economy. Docking in the Technology Development Zone and accelerating access to the photovoltaic industry chain." PV "Silicon Valley" is rising Deep inland Qinghai has always given people an impression of ecological beauty but economic and technological backwardness. In fact, the photovoltaic industry in Qinghai has already broken people's prejudice. "High precision" is now synonymous with photovoltaic in Qinghai. Up to now, Dongchuan Industrial Park in Xining Economic and Technological Development Zone has 71 high-tech and high-tech enterprises such as Asian Silicon, Convergence Power, Guodian Investment, and electronic materials. Only last year, it cultivated solar energy, concentrated energy, and titanium. Li optical fiber and other 4 technology and high-tech enterprises. It is these technological and high-tech enterprises that have promoted the optimization of the structure of the entire industry, radiated the park economy, fostered the development of industrial clusters, and created one after another scientific and technological achievements to enhance the capacity for sustainable development and created a brand of Qinghai PV. . In April of this year, the Asian silicon industry’s 48 R&D and large-scale application projects for rod reduction furnaces were assessed by the experts from the Ministry of Science and Technology of Qinghai Province as an international leader, becoming a representative of China’s advanced polysilicon manufacturing industry, and at the same time in the global industry. Leading position; Yellow River hydroelectric high-grade electronic grade polysilicon core production technology, successfully broke the foreign long-term monopoly, and occupied about 10% of the domestic market, the market share ranks the fifth in the world and the domestic first. At the same time, Guodian invested in solar energy Xining Branch to increase the average conversion efficiency of single-crystal batteries by increasing the single-crystal technological transformation project of battery production line and the introduction of the eighth-generation technology of batteries and the upgrading of the PERC process of high-efficiency single-crystal batteries for battery production lines. Raised to 21.4%, reaching the international advanced level, the photoelectric conversion efficiency of the module has reached the national photovoltaic leader plan requirements. In order to continue to accelerate research and development, Xining Economic and Technological Development Zone has established more than 33 city-level research and development centers and enterprise technology centers for high-performance light metal alloy deep-processing countries and local joint engineering research centers, silicon material technology research centers, and crystal silicon science and technology research and development centers. The company has a total of more than 300 patents of various types, including more than 50 patents for inventions, and the number of patents has increased year by year. "Green" development Green development, green industry, is not just the final result of production. The “green†in the Dongchuan Industrial Park in Xining runs through the whole process of production and in all aspects. The park's “all-in-one†green development is the best implementation of sustainable, clean, renewable and green development. All along, the park has not only added a threshold for entry into the enterprise, but also considered the degree of match between the company and the photovoltaic industry chain, and also required that the company's production be "green." In addition, enterprises that have already entered the park are actively guided to increase smart manufacturing, energy conservation and emission reduction. This year, a number of technological innovation and energy-saving technological transformation projects, including the technological transformation of the Circulating Cooling Water System (energy-saving) of Sunshine Energy (Qinghai) Co., Ltd., and the cold hydrogen energy-saving technology of Asia Silicon (Qinghai) Co., Ltd., were implemented. At the same time, a group of science and technology enterprises are using their own actions to implement green development: For the first time, the Asian silicon industry has applied the largest core technology for pressurized reduction furnaces with the largest monomer production capacity and the highest energy efficiency at home and abroad. While increasing production capacity, the reduction power consumption has been reduced to 40kwh/kg, and the single furnace output has increased to 12 Tons, the utilization rate of waste heat has been increased by 40%, the annual energy-saving standard coal is 36,000 tons, the electricity cost has decreased by 30% year-on-year, the gas cost has decreased by 70% year-on-year, and the comprehensive cost has been reduced by 40%. At the same time, relying on advanced technology of ultra-high-purity silicon tetrachloride purified by Asian silicon industry, Qinghai Zhongli Optical Fiber Technology Co., Ltd. has introduced optical fiber preform and wire drawing production projects to fill gaps in Qinghai Province's industry and is “high-grade†in Qinghai Province. "Industry projects have realized the integration and development between the two major industries of optical fiber and polysilicon, formed an effective complement between the new industry and new energy industries, and further extended the industrial chain of circular economy, which is an example of the implementation of a circular economy model in the global optical fiber industry." . The Yellow River Hydropower New Energy Branch has implemented annual savings in production costs of nearly 30 million yuan through the implementation of projects such as the recovery of surplus hydrogen, the comprehensive utilization of residual heat, the recovery of steam condensate from the distillation system, the optimization and reformation of the circulating water system, and the recovery of waste water. .
