On November 30th, as soon as the sky was bright, a truck carrying polysilicon raw materials slowly drove out of the Ganhe factory of Asia Silicon Industry in Ganhe Industrial Park, Xining (national) Economic and Technological Development Zone, and the destination was not outside the province, but Qinghai Gaojing Solar Technology within a few kilometers
At present, the first and second phases of the company's 2,200 monocrystalline furnaces have all been put into use, and an annual output of 30GW monocrystalline rods has been achieved. Of course, raw materials must be sufficient during this period**. To this end, we have established cooperation with local raw material production enterprises such as Asia Silicon and Lihao located in Xining Economic and Technological Development Zone. Ji Xiaoyun, executive deputy general manager of Qinghai Gaojing Solar, said.
As far as the development of industrial clusters is concerned, the proximity of raw materials between enterprises can not only save costs, but also the circular supply of the industrial chain in the region and the park is also the best solution for enterprises to "stay warm together" and strengthen the "circle of friends".
At noon in Qinghai, Gaojing, the office area is full of people, the sound of keyboard tapping and mouse clicks are intertwined, the participants in the all-glass conference room are nervously discussing, and the production goals and production line process improvement plans are switched back and forth on the whiteboard in the conference room.
Walk into Gaojing 6In the 70,000-square-meter modern monocrystalline silicon rod production workshop, the roar of machines resounded throughout the workshop, and 2,200 monocrystalline furnaces erected high were running non-stop, and workers in white uniforms shuttled through them.
In the morning, the polysilicon that had just been delivered from the Asian silicon industry was loaded into the n-type feeder and transported by the equipment to the monocrystalline furnace to wait for the furnace.
Ma Jianyu, the supervisor of the first workshop of Gaojing Solar, pointed to the feeding barrel in front of him and said: "This barrel of quartz feeding barrel contains 100kg of raw materials. ”
Shen Mianmei, a production assistant hanger, took a white towel to carefully wipe the quartz tube, "The key to hanging the material is to check whether the cylinder is broken to ensure production safety, and the second is to clean up the impurities on the surface of the quartz tube, so as not to affect the quality of crystal pulling and silicon rods." Without waiting for the conversation to finish, Shen Mianmei hurriedly went to the next single crystal furnace to carry out the hanging operation.
Watching the quartz cylinder slowly rise to full entry, the monocrystalline furnace began to run. Climb the yellow ladder next to the furnace and lean forward slightly to see the melted silicon inside the furnace through the small reddish window.
No one could have imagined that it would take less than a day for the polysilicon to roll off the production line in Asia and enter the Gaojing monocrystalline furnace in Qinghai, and the cooperation with local companies will double the production efficiency.
When he came to the machining department, the operator Jia Honglong stood on the No. 4 cutting machine to operate, his job was to "cut silicon rods", and saw 6 thin diamond wires cutting monocrystalline silicon rods at the same time. Jia Honglong said: "The company has been running at full capacity since the factory was built, and I need to cut 60 to 70 monocrystalline silicon rods every day. ”
At present, Qinghai Gaojing is at the world's advanced level in terms of technology, quality and scale, and for this reason, the 210mm large-size monocrystalline silicon rods and wafers produced by the company have been in short supply in the national photovoltaic market. As the first monocrystalline silicon rod manufacturer to settle in Nanchuan Industrial Park, Xining Economic and Technological Development Zone, Qinghai Gaojing has attracted and driven a number of high-quality photovoltaic accessories enterprises to settle in the park, which has played a great role in promoting Qinghai Province to build a national clean energy industry highland and the construction of two tens of millions of kilowatts of industrial bases.
Ji Xiaoyun said: "As of November this year, the company is expected to contribute more than 10 billion yuan in the case of full production capacity. We will continue to improve product quality, promote industrial upgrading, and continuously strengthen cooperation with upstream and downstream enterprises in Xining with the concept of a global benchmark enterprise in the field of photovoltaic silicon wafers, so as to achieve the goal of 'Made in Qinghai, Used in Qinghai'."
In the early morning, with the rise of the red sun on Tara Beach in Gonghe County, Hainan Tibetan Autonomous Prefecture, a piece of photovoltaic panels began another day's "labor", from the photovoltaic accessories production line of Xining Economic and Technological Development Zone to the photovoltaic power generation base in Hainan PrefectureFrom a monocrystalline silicon rod coming off the assembly line with high quality to photovoltaic panels to attract energy, it is precisely with the cooperation of photovoltaic accessories companies like Gaojing in Qinghai that the "light scene" has become a reality.
