  • Efficiency of 22.6% matches the TOPCon 600-650W median
  • At 226.1 W/m² power density, roof space requirements are typical for TOPCon 600-650W panels
  • At -0.29%/°C, hot weather performance is typical for TOPCon 600-650W panels
  • At 34.9 kg (2.3 kg above TOPCon 600-650W median of 32.6 kg), requires checking roof load capacity
  • 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces

Show series description

The Talesun BIPRO™ TM8G60M (120-cell) is a glass-to-glass bifacial module engineered for maximum yield from every square meter of installation. The use of N-type TOPCon cells and bifacial construction effectively utilizes reflected light from the ground – particularly effective on light-colored roofs, membranes, and ground-mounted installations. Thanks to the half-cut technology with a dense busbar layout, the modules perform better under partial shading and in low-light conditions, facilitating design in challenging locations.

Amidst many competitive panels, this product stands out due to its focus on long-term reliability – limiting LID and LeTID degradation and featuring enhanced resistance to PID – ensuring predictable energy production for years to come. This makes it an excellent choice for utility-scale PV farms, large commercial rooftops, and investors focused on long-term energy cost savings, not just peak power output.

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