Overview
Tongwei announced at Intersolar Europe 2026 the global launch of two new photovoltaic modules: the utility‑scale TNC 3.0 BIFIMAX and the residential‑focused TNC 2.0 G12R‑48. Both products are positioned as premium‑technology upgrades designed to meet diverse market requirements across utility and residential segments.
Utility‑Scale Module – TNC 3.0 BIFIMAX
The TNC 3.0 BIFIMAX module is certified by TÜV Rheinland and delivers a record bifaciality rate of up to 93.07%. It provides a maximum power output of 770 W and a conversion efficiency of 24.8%. The module incorporates a low temperature coefficient of ‑0.26%/°C, ensuring performance stability under high‑temperature conditions. Its Louvred Interconnection technology is claimed to boost micro‑crack resistance by over 100%, protecting the asset against heavy snow and strong winds.
Financial Impact Example
For a hypothetical 100 MW solar plant in Hamburg, Germany, the higher bifaciality is projected to generate an additional €180,000 in annual revenue compared with standard modules. Over the plant’s lifetime, this translates into an extra 81.62 million kWh of clean electricity production.
Residential Module – TNC 2.0 G12R‑48
The upgraded residential star module, TNC 2.0 G12R‑48, delivers up to 480 W of power with a conversion efficiency of 24%. Its compact footprint of under 2 m² maximises roof utilisation and simplifies installation for local crews. The module employs Tongwei’s 360° 3D passivation technology, reducing energy loss during low‑light periods and extending daily generation hours from earlier dawn to later dusk. Louvred Interconnection is also used to improve stress distribution, eliminating micro‑crack risks from heavy snow and strong winds common in high‑latitude European winters, while its uniform design aligns with modern residential aesthetics.
Conclusion
By launching the high‑yield TNC 3.0 BIFIMAX for utility projects and the aesthetically tuned TNC 2.0 G12R‑48 for residential roofs, Tongwei reinforces its commitment to delivering reliable, high‑performance solar solutions tailored to specific energy needs.
