The new module can reportedly achieve a power conversion efficiency of up to 24.8% and a bifaciality factor of over 85%.

Chinese PV module manufacturer Trina Solar has introduced its Vertex NG TSM-NEG19RC.20 TOPCon solar module series at the Smarter E trade show in Munich, Germany, this week.

“Our new bifacial dual-glass module series will be available in two variants aimed at covering the majority of utility-scale project requirements,” Adele Zhao, Head of Product Solutions & Marketing, Europe, at Trina Solar, told pv magazine. “The TSM-NEG19RC.20Q is a standard-format module designed for flexibility, particularly in projects with complex terrain or space constraints. Alongside it, Trina Solar is also launching a larger-format flagship version, the NEG21C, which is optimized for maximum power output and reduced system costs.”

“The 19R version offers flexibility for more challenging site layouts, while the 21-format delivers higher power and helps reduce balance-of-system costs such as cabling and mounting structures,” Zhao added. “Both versions are expected to enter mass production in the coming quarter, with availability beginning as early as next month.

The Vertex N G3 series is based on n-type i-TOPCon Ultra cell technology. The company describes the “Ultra” designation as the next evolution of its platform, incorporating further improvements to cell efficiency. “We improved passivation on both the front and rear sides, as well as at the cell edges, which enhances efficiency and improves both front- and rear-side performance,” Zhao stated, noting that bifaciality has increased to around 85%, supported by these cell and module-level optimizations. “The combination of improved passivation and bifacial performance contributes to higher overall energy yield while maintaining the same physical module footprint.”
