Smart Insights (data-driven)
  • Efficiency of 21.9% is 0.6pp below the TOPCon 450-500W median (22.5%)
  • Power density of 218.7 W/m² is 6.5 W/m² below TOPCon 450-500W median (225.2 W/m²) - needs more roof space
  • Temperature coefficient of -0.29%/°C matches the TOPCon 450-500W median
  • Weight of 28.1 kg is 4.1 kg above TOPCon 450-500W median (24.0 kg) - verify structural support
  • Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof

Show series description

The Talesun BIPRO™ TM3G54M (Bifacial Dual Glass, 108-cell) was designed to maximize energy yield where every square meter of installation counts. Thanks to its bifacial construction, the module can operate not only from the front side but also utilize light reflected from the ground—practical in white roofs, carports, and ground-mounted installations. The application of N-type TOPCon cell technology translates to more stable performance in high temperatures and better parameter retention over the long term, crucial for investment profitability. The dual glass structure with double glazing increases resistance to moisture and environmental factors, and enhanced PID resistance minimizes the risk of power degradation in demanding conditions. This is an excellent choice for installers and investors seeking modules for flat roofs, PV farms, awnings, and projects in windy, dusty, and variable weather conditions.
