Trina Solar’s Vertex modules pass extreme cold field test

Trina Solar’s 210 mm Vertex N 700W, Vertex N 610W, and Vertex 670W modules have passed extreme cold conditions and snowstorms during a field test in Mohe, China, where temperatures drop below -20°C for six months in a year. All the modules demonstrated stability and reliability, while Vertex N modules exhibited clear grid lines and no micro-cracks in the cells, even at temperatures as low as -53°C. A year-long outdoor test by China Testing and Certification International Group (CTC) and China General Certification at CTC’s extreme cold test park further confirmed the modules’ resilience, with Vertex N 700W generating 276 kWh in January, delivering performance under challenging conditions.
