Yingli photovoltaic power generation costs fall to below the market level of one yuan or face blowout
Two years ago, 13 PV companies, including Wuxi Suntech, Tianwei Yingli, Jingao Solar, and LDK, released the Luoyang Declaration, claiming to achieve the goal of 1 yuan per kWh of photovoltaic power generation in 2012. Today, this goal has been achieved ahead of schedule. Many reporters learned that the power generation cost of Yingli Green Energy Holdings Co., Ltd. (hereinafter referred to as “Yingliâ€), one of the largest PV companies in China, has been reduced to less than RMB 1/kWh. The insiders of Yingli Group confirmed the above statement. For a long time, the biggest bottleneck restricting the development of the domestic photovoltaic industry is that the on-grid price of photovoltaic power generation is much higher than that of conventional power. The cost of 1 yuan / kWh is considered to be the threshold for PV companies to open up the domestic market. In the bidding for the PV concession project in August 2010, the lowest bid price was about 0.73 yuan, which was less than 1 yuan. Meng Xianyu, vice chairman of the China Renewable Energy Society, said that under current conditions, photovoltaic power generation costs are still difficult to achieve generally below 1 yuan / kWh. However, he believes that the target of 1 yuan / kWh in 2012 will be basically achieved. One yuan cost price On the evening of May 20, Yingli will announce the 2011 first quarterly report. As of this newspaper's release, the relevant data has not been announced, but analysts predict that according to relevant data, Yingli's photovoltaic power generation costs will be less than 1 yuan / kWh in the first quarter. The "Luoyang Declaration" has made the "one yuan project" officially a common goal of the domestic photovoltaic industry. Only if the cost of generating electricity is less than 1 yuan, will the company be able to form a profitable space and its enthusiasm will increase. This means that the “one dollar†goal two years ago will be achieved. Yingli is one of the world's largest manufacturers of vertically integrated photovoltaic products. With a complete industrial chain in the photovoltaic industry, the company is considered to be the lowest cost PV company in the industry. The cost of photovoltaic power generation is divided into three parts: solar photovoltaic cells and components, materials and equipment and related packages. In addition, it also includes the cost of building a power plant, such as land, cable and other supporting facilities. Among them, component costs account for 70% to 80% of photovoltaic power generation costs. People familiar with Yingli said that in the field of photovoltaics, Yingli's component prices generally sell lower than their peers because they have their own silicon materials at a lower cost. Song Dengyuan, chief technology officer of Yingli Group, told this newspaper that the cost of upstream silicon materials accounts for more than 60% of the cost of photovoltaic modules. In China, the majority of silicon materials rely on imports. "At present, Yingli's silicon materials are only 60% more dependent on imports, and with the silicon plant's successive production and expansion, the external dependence of silicon materials will be further reduced." Yingli related sources said. In August 2010, Yingli announced that its subsidiary, Liujiu Silicon, was officially put into production. Liujiu Silicon is a subsidiary of Yingli, which mainly produces silicon materials. In addition, according to the plan, Yingli will also establish a 3,000-ton electronic-grade silicon material project in Hainan by 2013. According to the above sources, Yingli's silicon material is currently only 1,000 tons. If both projects reach 6,000 tons, the photovoltaic power generation cost will be greatly reduced. In addition, the conversion rate of solar cells is also critical. At present, Yingli's single crystal silicon and polycrystalline silicon solar cells have conversion rates of 19.89% and 18%, respectively. This is the highest conversion rate currently used for commercial production of these two types of solar cells. According to estimates, for every one percentage point increase in solar cell conversion efficiency, power generation costs can be reduced by about 7%. Can it be achieved? In fact, as early as 2008, Yingli proposed an ultra-low price of 0.69 yuan in the Dunhuang 10 MW photovoltaic concession bidding project. Miao Liansheng, chairman of the Yingli Group, once said that even at this price, Yingli is still profitable. However, the price of 0.69 yuan was not finally adopted. In the second phase of the August 2010 concession bidding, the lowest price of all projects fell below 1 yuan / kWh, the lowest offer is about 0.73 yuan / kWh of the Xinjiang Hami 20 MW project. Meng Xianyu said that the tendering enterprises of the second phase of the concession project are basically central enterprises, and can not truly reflect the actual situation of the entire industry. "Relatively, the data of leading private enterprises like Suntech and Yingli are more credible, and the cost trend of their photovoltaic power generation determines the trend of the whole industry," said a senior executive of the PV company, who asked not to be named. However, in Meng Xianzhao's view, if the principle of reasonable cost + reasonable profit is adopted, it is still difficult to reduce the power generation cost to below 1 yuan/kWh. "Companies like Yingli are few after all. However, it is predicted that in 2012, the power generation cost will be less than 1 yuan / kWh." Meng Xianyu said. The above-mentioned unnamed photovoltaic company executives said that the current photovoltaic power generation kilowatt investment is between 18,000 and 20,000 yuan, and the corresponding on-grid electricity price is 1.3 to 1.5 yuan. At present, Xuzhou GCL ground-based photovoltaic power station with GCL-Poly investment of 420 million yuan and a total installed capacity of 20 MW has become the lowest investment in domestic photovoltaic power generation kilowatts. This project is the largest solar power station with the largest installed capacity in China. Meng Xianyu revealed that the project can achieve a minimum investment of 16,000 yuan in kilowatts, and the corresponding power generation cost per kilowatt is close to 1 yuan, but the profit is meager. "It is estimated that by 2015, the investment in photovoltaic power generation will be reduced to 15,000 yuan, and then the power generation cost will be fully realized at 1 yuan per kWh." Meng Xianyu said.
