Smart Insights (data-driven)
  • Efficiency of 22.4% matches the TOPCon 650-700W median
  • At 223.7 W/m² power density, roof space requirements are typical for TOPCon 650-700W panels
  • At -0.29%/°C, hot weather performance is typical for TOPCon 650-700W panels
  • At 38.3 kg (3.4 kg above TOPCon 650-700W median of 34.9 kg), requires checking roof load capacity
  • Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface

Show series description

Trina Solar Vertex N modules are based on N-type cells in i-TOPCon technology, designed to maximize gains throughout the entire lifecycle of the installation. In practice, this means better performance at high temperatures and significantly more stable energy production over the long term – especially where predictability and low operational costs are key.

A major highlight is the dual-glass construction, which enhances resistance to moisture, temperature fluctuations, and micro-cracks. Combined with high bifaciality (in two-sided variants), the Vertex N series enables a truly significant gain when modules operate above a light-colored background or on elevated structures.

Vertex N is an excellent choice for utility-scale PV farms and commercial installations, where lower BOS costs, easier logistics, and compatibility with trackers are crucial. It stands out from the competition thanks to its refined platform for large-size cells and a focus on long-term reliability, rather than short-term paper gains.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
