What's the problem with double glass solar power plant of the exhibition?

Use of double glass component, also more and more high, especially in recent years, the country's vigorously support, makes the use of double glass components are also more common, but for the double glass component in the development of some of the problems, we understand very little, so, double glass components send

double glass components are also constantly improve the utilization rate, especially in recent years, due to the country's strong support, the use of the double glass components become more common. However, we have some problems in the double glass component development. So, what are the problems in the development of the double glass components? Since 2013, with built in early last grid-connected power generation of photovoltaic power station at home and abroad and run, appeared quality problem of large-scale power station at home and abroad. Many power plants are encountered quality problems, such as snails and PID attenuation. This issue has caused great attention of the quality of power station at home and abroad. Due to the short service life of organic materials, poor weatherability, photovoltaic modules of EVA start of attaches great importance to the quality of the film and the back. Due to the use of ethylene - of the inferior quality goods Vinyl acetate membrane, some 70% of the local power plant parts are in the large snails. Other power stations in one year after the operation found attenuation by 60%. In addition to the structure of rough, usually with residual ethylene - these problems Is directly related to the rapid degradation of vinyl acetate copolymer, the degradation is caused by water vapor through the backplane. Ethylene - Vinyl acetate copolymer was divided when exposed to water. Its differentiation product contains acetic acid, corrode the silver grid lines on the photovoltaic cells and bus-bar, lead to component output decline year by year. Some recent photovoltaic water projects, such as fish complementary, tidal flat power station, agriculture greenhouse and light photovoltaic project area with a large number of dew in the morning and evening, soon become a high-risk projects. Because power station owners are now in terms of kilowatt hours of their investment returns, the component of long-term reliability and durability as one of the main demand of photovoltaic components factory. Finally, with the widely application of the double glass components, the development of the double glass components problem, in fact, already began to appear, but with the development of new energy technology in China, these problems will be solved.
