Double, Sany, Guosheng and 6 other solar panel manufacturers failed the quality inspection, and 4 of them still did not pass the re-inspection.

Recently, the State Administration for Market Regulation organized a national supervision sampling inspection of 41 types of products. Among them, a total of 70 batches of monocrystalline silicon photovoltaic modules were inspected, and the results showed that 9 batches of products from Shanxi Huachu, Shuangliang New Energy, and Anhui Guosheng were found to be substandard. Among them, 7 batches failed the mechanical load test in the safety project, and 3 batches failed the power generation performance test under standard test conditions. Shanxi Huachu, State Power Investment Corporation New Energy, Dongying Dahai Kelin Optoelectronics, and Sany Silicon Energy were 4 companies whose re-inspection results remained unsatisfactory. In addition, some products related to Leneng were identified as counterfeits. In terms of solar module glass, 22 production units in 14 provinces including Anhui, Fujian, and Jiangsu were inspected, with a total of 22 batches of products. It was found that 6 batches of products had inadequate bending strength, including Haikong Sanxin, Anhui Shengshi, Jiangxi Ganyue, Hubei Yijun, Heyou Chongqing Guangneng, and Gansu Kaisheng Daming Guangneng. In response to the substandard products found in this sampling inspection, the market supervision department has taken measures such as removal from shelves, sealing, and seizure in accordance with the law, strictly prohibiting further sales from factories and urging relevant production and sales units to implement rectification.
