As the market's demand for high-efficiency modules grows, maximizing the benefits of power stations for investors has become a key focus of the industry. Continuous advancements in product performance, solid quality assurance, and service upgrades are crucial for enhancing competitiveness and gaining market recognition.

Since entering the module sector, Tongwei has consistently focused on product development to deliver greater value to customers, continuously striving for excellence. On March 20, after testing by the international authoritative certification body TÜV, the Tongwei TNC-G12R module achieved a front-side power of 682.8 watts and a conversion efficiency of 25.28% under the standard size of 2,382*1,134mm. The Tongwei TNC-G12 module achieved a power of 778.5 watts and a conversion efficiency of 25.06% under the standard size of 2,384*1,303mm, both exceeding the mainstream power of similar modules in mass production by approximately 60 watts, once again setting new records for the efficiency and power of the two mainstream TOPCon module types.

Moreover, TNC 2.0 fully leverages the advantages of TOPCon. In terms of technology research and development, Tongwei's TOPCon bifacial modules have achieved a breakthrough with a bifaciality rate of 88%+, which has been certified by a third party. By utilizing 908 technology (Tongwei's self-developed 0BB technology), screen printing, EPT edge passivation technology, Poly Tech, and other advanced technologies, TNC 2.0 achieves a comprehensive improvement in product performance, bringing value superior solutions to full-scene PV power plants.
