Harsh Times, HarshPower – CECEP PVB double-glazed modules in HarshPower Series
On August 22nd and 23rd, 2017, China Photovoltaic Industry Association (CPIA), China’s National Center of Supervision and Inspection on Solar Photovoltaic Products Quality (CPVT), China Electronic Information Industry Development & Research Institute (CCID) and China Electronics Standardization Institute jointly held the “Chinese Photovoltaic Products Quality Improvement Conference 2017” in Wuxi. CECEP Solar Energy Technology (Zhenjiang) Co., Ltd. (“CECEP Solar”) was invited to the conference, with Huang Qingsong, its head of research and development, delivering a keynote speech, HarshPower Series – PVB Double-glazed Modules and Batch Production Solution.
CECEP Solar pioneers PVB double-glazed modules to make use of the comprehensive performance of PVB film. PVB film has a long application history in plenty of areas and industries, including the building industry in which adhesive film normally does not appear. CECEP Solar has conducted various stringent comparative tests on PVB film, POE film, EVA film, etc, to check the maximum potential of PVB film. Based on these comparative tests, we found that PVB double-glazed modules have better weather resistance, vapor permeation resistance and shock resistance, service life of 30 years at least and an annual decay rate of 0.5%. In the life cycle of the whole system, the power benefit of such a module is 21% higher than that of conventional assembly, which has been verified in many farming-photovoltaic generation programs and fishing-photovoltaic generation programs.
CECEP Solar developed and researched the PVB production process for a long time, and finally found a process with superior overall performance (including optimum yield, highest productivity, lowest overall cost, etc.): rolling + autoclave. By virtue of this process, the disadvantageous price of PVB double-glazed modules can be reduced to the price level of conventional assemblies. Therefore, combined with its superior reliability, we believe that PVB double-glazed modules will be applied in more areas in the future.
As the leading producer of photovoltaic cell and assemblies and a wholly-owned subsidiary of CECEP Solar Energy Co., Ltd. (a major central enterprise in China), CECEP Solar Energy Technology (Zhenjiang) Co.,Ltd. won the National Award for Science and Technology Progress because of the double-glazed technology in early 2017, and thereby becomes the only enterprise being granted with such an award in the photovoltaic industry — Harsh Times, HarshPower!
