  • Module efficiency of 21.9% is 0.9pp below average for TOPCon 600-650W panels (median: 22.8%)
  • At 219.1 W/m², this panel generates 8.6 W/m² less per unit area than TOPCon 600-650W median (227.7 W/m²)
  • Temperature coefficient of -0.29%/°C matches the TOPCon 600-650W median
  • At 34.9 kg (2.3 kg above TOPCon 600-650W median of 32.6 kg), requires checking roof load capacity
  • Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof

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 →
