Tongwei to showcase TNC 3.0 series at Intersolar Europe 2026

The centerpiece of Tongwei’s presence at this year’s Intersolar Europe will be the TNC 3.0 series — the company’s next-generation flagship module, engineered to deliver more power, more reliability, and more returns across every installation scenario.

In the G12R-66 format, the TNC 3.0 series module reaches a maximum output of 670 W at a conversion efficiency of 24.8%. Stepping up to the larger G12-66 format, output climbs to 770 W, while sustaining 24.8% efficiency. This positions the TNC 3.0 among the highest-performing 210 mm modules available today.

The TNC 3.0’s quarter-cut cell design reduces operating current by 75%, working in tandem with a lower power temperature coefficient to keep module temperatures in check. Even under intense midday sun scenarios, the TNC 3.0 stays “cool” — minimizing heat-induced losses and delivering stable, consistent output over time.

Tongwei has reengineered the internal current path structure of the TNC 3.0 module, upgrading the parallel circuits from two sections to four sections. This upgrade is equivalent to expanding the power transmission channels into independent, non-interfering “four-lane” highways. When part of the module is shaded, current can quickly divert through the remaining three clear “lanes.” This high-redundancy circuit design minimizes power generation loss caused by partial cell shading, significantly enhancing the module’s anti-shading capability under non-ideal conditions.

Tongwei’s Poly Tech technology delivers 85% bifaciality as standard for the TNC 3.0, allowing the rear side to capture meaningful additional energy — particularly in high-albedo environments where reflected light translates directly into revenue. For projects where rear-side generation is a priority, the TNC 3.0 is also available in BIFIMAX option, pushing bifaciality to 90% and unlocking even greater yield in high-latitude or high-reflectivity settings.

Over the long term, an ultra-low annual linear degradation rate of just 0.35% means the module holds its ground year after year — delivering more energy, and more value, than conventional modules over its 30-year lifetime.
