The chaotic domestic PV market has seen a new turn. At the Shanghai Photovoltaic Exhibition, which is known as the industry's vane, many companies have not thrown up various expansion plans like last year, but they have shown the latest research and development technology. Many companies claim that they will be technically and will abandon endless prices. war. Li Xianshou, chairman of Suihui Sunshine, told reporters, “It is an insult to let me go to the low-cost domestic PV bidding. We will not participate in any price wars in the future.†“The turn is obvious.†TüV SÜD Xu Hailiang, manager of the Central China Photovoltaic Products Department of China Group (hereinafter referred to as TüV), told reporters that as one of the world's largest third-party technical inspection and certification institutions, the group accepted more than 100 domestic PV companies' testing applications and participated in inspection and certification. Domestic companies are growing rapidly. He believes that China's PV companies are gradually abandoning the competitive strategy of winning by scale and low price, and they are turning to technology and quality. A technical war will replace price wars. The lack of standards For a long time, it is an open secret that some domestic PV products are different from those sold abroad. "Most of the exported products will be better than the products sold in China." A person in charge of a photovoltaic company in Jiangsu told reporters. He revealed that PV products sold in Europe must pass TüV quality certification, and products sold to the US market must also be certified by third-party organizations such as UL, otherwise it is impossible to enter these markets. The person said that compared with foreign strict certification, China has not been able to establish quality standards for photovoltaic products in the past few years, and some domestic PV power plant builders also choose cheap products in the bidding, do not care about the poor quality of products. “In 2009 and 2010, when the domestic PV market was just launched, in the bidding project of Golden Sun Engineering, because the low price was won, the quality of the product was serious, and the small factory sold the inferior product for the cost. Digesting stocks and selling defective products, the atmosphere is very bad." "In some projects, a few photovoltaic companies and power station developers have partnered together to defraud state subsidies, and even used cardboard to color the batteries to cope with inspections." . He said that the country has issued some regulations for this purpose, but these regulations have not been refined and cannot be landed. Therefore, the quality of domestic products has been plaguing China's photovoltaic market. Xu Hailiang told reporters that relatively speaking, the quality requirements for building photovoltaic power plants abroad are very strict, so inferior products cannot enter. He said that small photovoltaic power plants in Europe are self-sufficient in factories, and they will test the amount of electricity generated 24 hours a day. If there is a problem, they will complain; and the builders of large-scale photovoltaic power plants must make money by selling electricity. Inferior products will not be purchased; and some builders are to be financed by power stations. If there are quality problems in the power station, the corresponding valuation will be greatly reduced. An insider of Zhongsheng Optoelectronics believes that the reason for some product quality problems in China is that the photovoltaic standards that have been compulsory certification by relevant state departments have not been introduced, and they can only rely on the self-discipline of enterprises. However, due to the serious excess of the market, the competition is fierce. In order to survive, enterprises have to lower the standard sales products, and the price war has gradually increased the harm to the development of China's photovoltaic market. "The era of low price is king." Xie Fangji, head of Jiangsu Aide Solar Technology, told reporters that the company's single crystal module products have just passed the TüV PID (potential induced decay test) test. According to him, because it directly affects the power attenuation of the battery, it has become the basis for many power station builders to purchase products. However, domestic builders were concerned only about the price, and rarely considered the product quality. "The obvious change now is that they have begun to pay attention to the conversion rate and attenuation of the battery." Qunhui Sunshine Sales Department told reporters that the current production costs of first-line companies are basically the same, and there is no price war. Many cards can be played, and they are currently in a state of glue. "So in this situation, if the company's products can break through in terms of conversion rate, attenuation rate, etc., the price/performance ratio will naturally increase, and more markets will be won. Therefore, everyone is looking for a technological breakthrough.†The above-mentioned people also revealed that the first-line companies such as Suihui Sunshine, LDK, and GCL-Poly have jointly drafted the standards for photovoltaic cell components with SEMI China. “The first draft will be completed in August. Although this is only an industry association's regulation, it also provides reference and basis for the development of detailed standards at the national level in the future. The NDRC may also introduce its own PV quality standards early next year. The route dispute is still in transition. China's photovoltaic industry also has a dispute between the two technical routes of crystalline silicon and thin film. Before 2009, thin-film batteries had the opportunity to compete with crystalline silicon cells. At that time, the conversion rate of thin-film batteries was only 7% to 8%, which was far from the 14% of crystalline silicon cells, but the cost was only crystalline silicon cells. One-half of the price, but since the price of polysilicon has dropped from the peak of $400/kg to the current $25/kg, the film's low-cost advantage has been lost. According to the reporter's understanding, the current share of film in the global market is less than 20%, the rest are crystalline silicon cells, and in China's first-line photovoltaic companies, including Suntech, Yingli, Jingao, etc. are basically crystalline silicon manufacturers, and The world's largest manufacturer of thin-film battery equipment, US Applied Materials, also stopped selling the equipment due to business losses, and the film equipment manufacturer Oerlikon Germany also sold all the production lines. "Film can find a market segment, but it is by no means the mainstream." Li Xianshou told reporters. He believes that price war is not good for people, and technological innovation is the only way to get PV out of the predicament. Since 2009, the company has invested about 200 million yuan in research and development every year, all of which are in the field of crystalline silicon cells. Feng. According to Li, the latest technological innovations are the resin diamond cutting line and the new Virtus components. The former greatly improves the productivity of single equipment and the conversion efficiency of the battery. Virtus can convert the average conversion efficiency of conventional polycrystalline silicon batteries to about 16.5%. Increased to 18.2% or more, and recently TüV also issued a certificate to the Virtus component, indicating that the Virtus component has been recognized worldwide. He believes that many PV companies have entered a misunderstanding of the whole industry chain from polysilicon to components. In those years, these companies that have been fully industrialized have also made money, but now they have fallen into a quagmire because of the sharp drop in profits. As the market matures in the future, companies that focus on one aspect of the industry chain are clearly more competitive. “昱辉 is insisting on specialization. In the second quarter of this year, our component sales increased by 100%, and the signs of recovery are obvious.†Li Xianshou said that China’s PV industry is now in a period of transformational pain, and many companies are suffering unprecedented Pain and hardship, the survival of the fittest makes the enterprises with poor strength out, and the big companies like Qihui have started the transformation path, starting from production and manufacturing, and starting to transform into R&D and market. Zhongsheng Optoelectronics told reporters that in fact, no matter whether it is crystalline silicon or thin film technology, companies will have a good harvest if they are serious about R&D. For the whole industry, it will also bring new atmosphere. However, he also believes that technology research and development can not be completed overnight, and breakthrough technological changes often take several years. For example, the first solar cadmium thin film battery in the United States has been developed for seven or eight years, and domestic efforts like Suntech and Qihui Companies that invest in research and development naturally have, but it is inevitable that some companies are fishing in the water. Photovoltaic equipment manufacturer Manz of Germany also produces both crystalline silicon and thin film production equipment. Its executives told reporters that they are more optimistic about thin-film batteries, because the cost and conversion rate of crystalline silicon batteries have reached the bottom, and it is difficult to reduce them. There are still breakthroughs in thin-film battery technology. "The copper-indium-gallium-selenide thin-film battery equipment we developed has a conversion rate of 14%, but the cost is somewhat high. If the cost can be reduced below the crystal silicon, I believe it is more Competitiveness." "If some domestic PV companies are unsettled, just using technology as a gimmick, it will inevitably fall into a farce under the name of technical warfare." The above person reminded.
