MUNICH, July 17, 2026 /PRNewswire/ — Tongwei made an impact at Intersolar Europe 2026, launching its premium technology upgrade, TNC 3.0 BIFIMAX, alongside the upgraded residential star module, TNC 2.0 G12R-48. Pairing industry-leading efficiency milestones for utility projects with aesthetic solutions for residential roofs, Tongwei demonstrated its commitment to meeting diverse, global market needs.
The Powerhouse for Utilities: TNC 3.0 BIFIMAX
The exhibition’s highlight was the global debut of TNC 3.0 BIFIMAX, representing a major technical breakthrough that delivers maximum energy yield on high-reflection surfaces.
Certified by TÜV Rheinland, TNC 3.0 BIFIMAX achieves a record bifaciality rate of up to 93.07%, alongside power output up to 770W and conversion efficiency up to 24.8%.
- Higher Financial Returns: Higher bifaciality allows the modules to generate much more power from the rear side—delivering a free energy bonus. For a 100MW solar plant in Hamburg, Germany, this configuration generates an extra €180,000 in revenue annually compared to standard modules, unlocking an extra 81.62 million kWh of clean electricity over its lifetime.
- Built for Extremes: Featuring a low temperature coefficient of -0.26%/°C, it remains highly efficient under scorching heat. Its specialized Louvred Interconnection boosts micro-crack resistance by over 100%, protecting the asset from heavy snow and strong winds.
Tailored for Residential Roofs: The Upgraded TNC 2.0 G12R-48
To meet the growing demand for premium home solar, Tongwei also unveiled the upgraded residential star product: the TNC 2.0 G12R-48. This module balances top-tier performance with home aesthetics.
- Maximum Power in Golden Size: The module delivers up to 480W with a 24% conversion efficiency. At a compact size of under 2 m², it maximizes limited roof space and makes installation much easier for local crews.
- Extended “All-Day” Generation: Powered by Tongwei’s 360° 3D passivation tech, the module minimizes energy loss and improves performance during low-light hours. This extends daily generation hours—starting earlier at dawn, ending later at dusk.
- Extreme Weather Protection & Sleek Look: Featuring Louvred Interconnection tech, the module ensures better stress distribution. This effectively eliminates micro-crack risks caused by heavy snow and strong winds common in high-latitude European winters. Additionally, its uniform, elegant design blends seamlessly with modern residential architecture.
By delivering both the high-yield TNC 3.0 BIFIMAX for utilities and the aesthetic TNC 2.0 G12R-48 for residential markets, Tongwei continues to provide reliable solar solutions tailored to specific energy needs.
