Photovoltaic Powers Expect Missing Over 80% of Industry Standard Standards

In the past, China has become the world’s largest manufacturer of photovoltaic cell modules and has formed a complete industrial chain that includes silicon materials, silicon wafers, cells, components, and application systems. Scientific and standardized quality and technical standards provide the basic guarantee for the healthy development of the industry. However, the reporter found in the survey that the relevant standards, especially the unified national standards, lag behind the development of the industry and become shortcomings that urgently need to be filled.

Current status standards generally lagged behind the development of the photovoltaic industry. “The domestic photovoltaic standards are not perfect, and even lag behind the entire industry, and do not match the status of photovoltaic product manufacturing countries.” Shen Fuxin, secretary general of the Zhejiang Solar Energy Industry Association, said.

Then, is China's photovoltaic industry's standard setting really the same as Shen Fuxin? To this end, the reporter conducted a further investigation on the development of the photovoltaic industry standards, trying to tease out the pulse of the development of industrial standards.

The national standard for polysilicon materials may be issued in the first half of the year. “At present, two standards, namely “Solar-grade polysilicon film” and “Solar-grade cast polysilicon block” involving the solar photovoltaic industry chain, have been completed.” Shi Xu, President of Shanghai Pronew Energy Co., Ltd., told According to the reporter, the above two standards have already passed the review by the National Standards Committee and are publicizing that “the batch number has not yet been obtained. They are expected to be formally released in May and June of this year. Now is the walk-through procedure.” Before that, “Solar-grade polysilicon” has long been the benchmark. The publication, however, Shi pointed out that when the standard was formulated, it was not accurate enough to grasp the name of the standard. He once proposed to the standards development group that the standard should be changed to “pre-doped solar-grade polysilicon”. The establishment group also agreed .

Prior to the official release of the national standard, most of the production companies are implementing the corporate standard. “The corporate standard is more stringent than the soon-to-be-released national standard, and the required purity and conversion rate are higher.” In addition, due to the relatively late formulation of the national standard in China. The starting point is high, so the requirements are stricter than those of Europe, America, etc. For example, the conversion rate is generally 10% for foreign countries, 14.5% for our national standard, and 16% for manufacturers.” The high conversion rate is to "sell a higher price."

Most of the battery packs are based on foreign standards. "Where there is a standard for self-preparation, it basically refers to foreign countries and cannot meet foreign standards. You should not mix in this circle," said a person in charge of a large photovoltaic cell module manufacturer in China. . When asked what national standards for photovoltaic modules are in the end, the person in charge ambiguously stated, “There should be some national standards. We are all producing according to our own corporate standards or the standards of the exporting country.” People explained that 95% of China's photovoltaic cell modules are exported, so long-term foreign standards have been implemented. "If you export to the United States, for example, you must implement US standards and obtain UL certification." Meng Xianzhu, deputy director of the China Renewable Energy Society, euphemistically He pointed out: "Our standards are based on international standards and combined with China's national conditions. From the outset, we have been in line with international standards." "It has been said that the photovoltaic industry is on the outside and the battery components are exported for a long time, which determines its standard. Must also be internationalized.” In addition, some domestic battery module manufacturers are actively participating in the preparation of the national standard in order to win the right to speak in the market, and strive to promote their own corporate standard upgrade to the national standard, such as the recent domestic first polysilicon The standard for processing unit consumption of solar photovoltaic modules is based on the production process of Yingli Group. of.

In order to more fully understand the development status of the PV module standard, the reporter has repeatedly tried to contact the National Standardization Technical Committee for Solar Photovoltaic Energy Systems. However, due to the unsuccessful replacement of the unit’s office address, the reporter repeatedly called the company’s telephone number on the Internet. No one has answered yet.

The lack of national standards for power plant construction, grid connection and other “photovoltaic standards are mostly concentrated in the production of battery modules. There is basically no photovoltaic power station construction and construction national standard. This is difficult to obtain.” Li Hongbo, general manager of Shanghai Solar Energy Technology Co., Ltd told the reporter. He explained that “Comparing with the standard of components, setting the standards for the construction of power stations is much more complicated and the impact factors are more complex. We must consider the natural conditions of hydrology, geology, sunshine, and the needs of owners in different regions. We must also consider the cost. It is understood that the company is building a 50 MW photovoltaic power station in Zhangye, Gansu Province. “At present, there is no mandatory national standard for construction. We are building according to our own assumptions. After completion, who will test it and follow it? Standard acceptance is still a problem.” Meng Xianzhe also told reporters that overall, China's national standard in the field of photovoltaics is not perfect, especially the absence of power plant detection and acceptance standards is even more prominent.

Wei Qidong, former secretary general of the Photovoltaic Industry Association of Jiangsu Province, said. At present, China has officially issued dozens of photovoltaic national standards, but the entire industry still lacks 80% of the standard specifications.

The countermeasures have been established to govern the integration of standard management by specialized organizations. “Industrial development is too rapid, the system is incomplete, and the management is not yet clear. Standards have a long development cycle and cannot keep up.” Talking about the lack of relevant standards for photovoltaic national standards, especially for power plant inspection and acceptance When it came to reasons, Meng Xianyi analyzed.

"There is no quality without standards"

Meng Xianzhe pointed out that "project construction must have standards, standards involving the lifeline of project quality, do not implement the mandatory standards, project quality can not be guaranteed, the service life will be shortened, its negative impact is obvious. It's just a box or a means. Even so, it is a bottom line that must be observed." He said that China's photovoltaic industry has developed rapidly in recent years. "Many projects are confused and done," many energy service companies Without actual operational experience, it is necessary to do the project. The management right is again within the company. It cannot be supervised at all. “The supervision is not perfect.” The lack of standards makes the quality of the project even more untenable.

“At present, the photovoltaic power plant project certification system and standard system are not perfect. After many projects are completed, most of the investors invite some industry experts to conduct a review meeting. No one must carry out compulsory inspection and certification of the project. The quality of the project naturally varies."

We hope to clearly manage the management. "In fact, the national plan also mentions the issue of standard setting. However, the current system is not perfect. The management of the new energy industry is unclear, and it has virtually increased the difficulty of standardizing unified work," Meng Xianlu said.

Similar to the above, Shen Fuxin and Li Hongbo both stated that the current multi-headed management of the new energy industry has dragged on the preparation of standards and the mechanism and mechanism have yet to be defined and improved.

To this end, the above-mentioned respondents in the industry hope that the country should establish a dedicated and comprehensive management department as soon as possible. However, the above-mentioned sources also stated that this idea is too difficult, and that “it is not easy to balance the interests of all parties”.

Under the existing system, a compromise solution is to establish a joint mechanism, such as the establishment of a cooperative management agency, to coordinate and coordinate the related work of various departments such as the Ministry of Housing and Urban-Rural Development, the Ministry of Finance, and the National Energy Administration.

Relying on the growth of the photovoltaic industry itself, in addition to the above-mentioned industrial development speed and institutional factors, Meng Xianjun also pointed out that the lag in standard preparation is also related to the actual scale of the photovoltaic industry itself. “In the past, all were vain, and various projects were on the cutting edge. We did not consider power generation at all. In 2010, the amount of solar power generated by the grid was only 72.16 million kWh, which accounted for only 60,000 of the total. In addition, the total installed capacity of photovoltaics in the country in 2011 was 2.9 GW. The data can be seen that in fact, the actual scale and contribution of the photovoltaic industry are very small, and the government cannot pay too much attention.” “In the future, as the market expands and matures, the scale of the photovoltaic industry will really go up, and relevant standards will surely gradually improve. This is a process and it cannot be rushed."
