At Intersolar Europe 2026, Tongwei disrupted the renewable sector by launching the TNC 3.0 BIFIMAX, a module boasting unprecedented bifacial efficiency and power output.

Key Takeaways

  • Tongwei launched the TNC 3.0 BIFIMAX with a record-breaking 93.07% bifaciality rate.
  • The module offers up to 770W power output and 24.8% conversion efficiency.
  • New TNC 2.0 G12R-48 residential modules prioritize aesthetics and low-light performance.
  • Advanced Louvred Interconnection technology enhances resistance to extreme weather.

MUNICH, GERMANY: In a landmark moment for the renewable energy industry, Tongwei has set a new global benchmark at Intersolar Europe 2026. The company officially debuted its flagship TNC 3.0 BIFIMAX module, a technological marvel designed to maximize energy yields through unprecedented bifacial efficiency.

A Paradigm Shift for Utility-Scale Projects

The centerpiece of the exhibition, the TNC 3.0 BIFIMAX, has achieved a staggering 93.07% bifaciality rate, as certified by TÜV Rheinland. This allows the module to capture significantly more reflected light from the rear side, effectively turning surfaces into high-yield energy collectors. With a power output of up to 770W and a conversion efficiency of 24.8%, it is engineered specifically for large-scale utility projects.

The financial implications are profound. For a hypothetical 100MW solar plant in Hamburg, Germany, this high-efficiency configuration could generate an additional €180,000 in annual revenue compared to conventional modules. Over its operational lifespan, this translates to an extra 81.62 million kWh of clean electricity, providing a massive boost to the Return on Investment (ROI) for solar developers.

Redefining Residential Solar Aesthetics

Recognizing the shift toward decentralized energy, Tongwei also introduced the TNC 2.0 G12R-48, an upgraded residential star module. Designed to blend seamlessly with modern architecture, this module provides up to 480W of power within a compact footprint of under 2 m². Utilizing 360° 3D passivation technology, it ensures extended generation windows, capturing energy from the early dawn to the late dusk, even in low-light conditions.

Engineering for Resilience

Beyond efficiency, Tongwei has addressed the critical challenge of durability. The integration of Louvred Interconnection technology increases micro-crack resistance by over 100%. This makes the modules exceptionally resilient against heavy snow loads and high-velocity winds, common in high-latitude regions. By combining extreme weather protection with high-performance output, Tongwei is positioning itself as a leader in the global transition toward sustainable, reliable energy infrastructure.
