Recently, Maywon completed a customized photovoltaic clamp pull-out force test for a core client's photovoltaic power plant project in Southeast Asia. All test indicators met the client's established requirements, providing direct data support for the reliability of the client's project component installation. The core requirement of this client's commissioned test stemmed from the unique operating conditions of their photovoltaic rooftop project—located in Thailand's Eastern Economic Corridor, facing high temperature and humidity, frequent typhoons, and high salt spray environments year-round. Verification of the clamp's pull-out load-bearing capacity, deformation resistance, and weather resistance stability under these conditions was necessary. To this end, Maywon Solar worked closely with the client's technical team to clarify three core testing requirements: a pull-out force of no less than 70kN, a strength decay rate of ≤3% after 50 thermal cycles, and no loosening under simulated typhoon-level dynamic load. Based on the client's specific needs, the testing team developed a customized solution: strictly adhering to the client-specified IEC 62715 international standard and the Thai PEA-2016 grid connection requirements, accurately simulating the actual environmental parameters of the client's project site, and testing 5 sets of aluminum alloy fixture samples that were completely consistent with the client's project specifications. The entire testing process was witnessed on-site by the client's technical personnel: the technical team monitored the fixture stress distribution, displacement data, and interface sealing status in real time, synchronizing test curves and interim data with the client every 2 hours. Regarding the client's question about "stress concentration under dynamic load," real-time data was retrieved and analyzed on-site. The final test results showed no loosening or deformation during the dynamic load test, fully meeting the client's established standards. "The testing process was transparent, the data was accurate, and the results fully met our project requirements," said a representative from the client's on-site witnessing team. They added that Meihong Photovoltaic's testing solution accurately addressed the actual working conditions of the project, and the real-time data synchronization and professional analysis gave them complete confidence in the reliability of the fixtures. The project manager of Meihong Solar responded, "This testing process was entirely customer-centric. From parameter settings to process verification, everything was tailored to the actual project requirements. The goal was to address the customer's practical concerns through solid test data." It is understood that after the testing was completed, Meihong Solar has issued the customer a complete test report including raw data, curve reports, and third-party (Thailand TISI) verification results. The customer will proceed with subsequent module installation based on this report.
