The modules underwent a series of rigorous tests as part of the process, receiving an overall positive result. This is a powerful endorsement of the quality, reliability, and durability of Trinasolar’s n-type module portfolio and provides further proof for global buyers, procurement teams, and bank financing services that invest in the company’s products. This has laid a solid foundation for further expanding Trinasolar’s global market.

TÜV Rheinland conducted its tests based on the Bankability 2 PfG 2940 standard. These tests included thermal cycling sequencing, sequential mechanical stress testing, sequential stress testing on the module rear side including UV radiation, damp heat sequencing, potential induced degradation (PID) testing, UV-induced degradation (UVID), light and elevated temperature-induced degradation (LETID) detection and optional PAN file examination.

The module performed especially well in the thermal cycling sequencing, sequential mechanical stress testing, and sequential stress testing on the module rear side, including UV radiation and LETID test, displaying extremely low levels of attenuation. This aligns strongly with other tests conducted by Kiwa PVEL in 2023 and the Renewable Energy Test Center (RETC) this June.

Li Weichun, Global Head of Power Electronics and General Manager of Solar & Commercial Products, Greater China at TÜV Rheinland Group, stated, "Trinasolar's Vertex n-type TOPCon bifacial modules performed exceptionally well in our Bankability test, confirming their industry-leading quality and reliability. We have worked closely with Trinasolar in bankability, product carbon footprint, EPD certificate, and product reliability and are looking forward to strengthening our collaboration with Trinasolar in the near future."

Wang Bing, Operational Quality Head at Trinasolar's Cell and Module Business Unit, stated, "Trinasolar has always championed a 'quality first' and 'customer first' philosophy, which has helped our products earn a strong reputation in the market.”

“This certification reaffirms Trinasolar's approach to technological research and development and our emphasis on continuously improving the performance and reliability of our products. We are passionate about bringing solar energy to more communities globally and recognize bankability as crucial to achieving this goal."
