Trinasolar has unveiled its Vertex N G3 series multi-cut TOPCon module with dimensions of 2,384 × 1,134 × 30 mm
It has a maximum rated bifaciality of 90%
This module is expected to be commercially available in Q3 2026
China-based TOPCon cell and module maker Trinasolar has launched its latest Vertex N G3 series multi-cut module, catering to utility and AI data center (AIDC) applications.
According to the company, the module uses 264 G12-size cells, each cut into 4 equal parts (1/4-cut) along the length. It measures 2,384 × 1,134 × 30 mm and is rated for a maximum power output of 760 W. Without sharing the efficiency, the company attributes its 281 W/m² power density to cut cell edge passivation technology and the architecture of the cell layout. The former technology passivates along the laser-cut edge, which is typically prone to serving as recombination centers for minority charge carriers.
While the company didn’t share the details on cell-to-cell interconnection and layout, it states that these improve the module’s active cell areas. This dual-glass product offers a bifaciality of up to 90%. The lower leakage path and high shunt resistance (Rsh) characteristics of these cells help the module generate additional power in low-light conditions, compared to conventional BC peers. However, the company didn’t quantify these gains in the press release.
In terms of shade tolerance, this module’s multi-cut cell layout with a shorter current travel length results in lower power losses compared to half-cut-cell-based counterparts. While Trinasolar didn’t quantify these improvements, the reduction in the operational temperature of shaded cells lowers the module’s hotspot risk.
The company expects this module to be commercialized in Q3 2026.
