Solar power as a clean energy applications have been developed for many years, and now the technology is relatively mature, has entered every household. Statistics show that in 2013 China's new PV power installed capacity of 12.9 GW, the world's largest photovoltaic applications. 2014 China PV power plant construction will reach 10-12 GW, accounting for a quarter of global.
But brutal development of the industry has also brought many problems, the National Energy Board recently made clear that in some areas, and supporting grid PV power plant construction are not synchronized, project management is not standardized, weak standards and quality management issues outstanding.
AQSIQ recently released a report checks for solar photovoltaic modules with anti-reflective coated glass product quality supervision and spot checks, the results surprising, sampling of 30 companies 30 kinds of products, 23 kinds of only 23 companies product qualification, sampling corporate yields and product qualification rate was 76.7%.
The report shows that this sample test involving seven projects, including debris state, shotgun bag impact properties, optical properties, resistance to a clean slate, resistance to neutral salt spray, humidity freeze properties, UV resistance. Where debris state, shotgun bag impact safety performance indicators related to the product after installing the photovoltaic modules, photovoltaic modules using secure. The results show that failed mainly for moisture and debris frozen performance status.
In fact, these risks would have exposed the reality of recent years in the western region of photovoltaic power plants frequently exposed quality issues. According to a report by a third-party testing organization Beijing General Certification Center, the country has surveyed 425 solar power plants, 30 percent more than three years to build power plants have experienced varying degrees of problems.
Some blame the high subsidies and low acceptance criteria Golden Sun works in previous years, resulting in a lot of western power plants there are serious quality problems. Life expectancy is 25 years of power plant operation, follow-up questions will become increasingly serious.
Frequently exposed photovoltaic plant quality problems make the National Energy Board recognized the seriousness of the problem, has taken a series of measures to rectify. And the use of certified products meet the national targets Express document recently issued "on further strengthening PV power plant construction and operation management notice" from the 11 aspects of photovoltaic power plants were standardized, and require the project unit equipment procurement tender .
