3. Current Adaptation Reliability Test to Ensure Safety In line with the current output chang - es in the 600W/550W series modules, Trina Solar’s R&D team has conduct- ed a series of reliability tests, such as reverse current overload test, diode junction temperature test, junction box thermal runaway test, thermal cycling test, etc. When the bypass diode in the PV module is turned on outdoors, and the output current Isc=18.6A (the current of modules under usual op - erating condition generally does not exceed Imp≈17.5A under STC), the operating temperature of the diode is about 120℃. The current change will not increase the safety risk of the diode. Meanwhile, for the first time in the industry, the Vertex 550W/600W series modules have recently passed the reliability tests provided by third-party TüV Rhineland, which fur - ther demonstrates the excellent reli- ability and safety of Trina Vertex PV modules. 4. Excellent Low-Irradiation Per- formance Ensures Reliable Power Generation The Vertex 600W/550W series mod- ules use a unique technology to en- sure high power generation and op - timize the fill factor of the modules to improve low-irradiation performance. Taking Changzhou as an example: PR200 W/m2 has been increased by 0.99%, and the energy yield gain in - creased by 0.68%.

Short-Length and Two-Layer Ver- tically Stacking Packaging Method By improving the vertical space uti - lization of the container, short-length and two-layer vertically stacking packaging method are used. The packing wattage of the standard con - tainer is further increased by about 9% compared to the first generation of Vertex, which provides our custom - ers with a more economical, safe and reliable logistics solution. 31 energetica INDIA- October_2020
