Tongwei will bring its next-generation flagship solar model – the TNC 3.0 series – to Intersolar Europe 2026 along with a lineup of additional new products and solutions.
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.
