On February 19, Tongwei unveiled its newly upgraded TNC 2.0 products at the PV EXPO 2025 and showcased high-efficiency modules such as the TNC-G12R 48/54/66 HD and TNC-G12 66 HD to the Japanese market, drawing attention from numerous industry experts and customers. The debut of TNC 2.0 modules in Japan fully demonstrated Tongwei's strong strength in continuous innovation in the field of PV technology.

In Japan, the PV sector is developing rapidly with the increasing demand for distributed PV, while market players pay more attention to high-efficiency and reliable modules and long-term returns. "The core of the market is demand, and the most direct way is to engage in the front line." During the PV EXPO 2025, Qiu Xin, General Manager of Global Module Marketing from the PV Business Department of Tongwei Co., Ltd., visited the site to conduct in-depth discussions with customers and gain insights into market trends, policy dynamics, and user needs.

"High efficiency, high reliability, low degradation, excellent low-light response, and long-term profitability allow for greater product value to customers," said Mr. Qiu, "The upgrade of TNC 2.0 modules is not only a technological advancement but also Tongwei's precise matching of market demands."

He also emphasized, "The development of the PV sector ultimately lies in the integration of technology and demand. Only by deeply understanding customers' pain points and keep innovating can we maintain global competitiveness."

Improvement of quality and efficiency

The comprehensive upgrade of TNC 2.0

Faced with the global PV sector's accelerating trend towards high efficiency and low cost of electricity, Tongwei has taken technological innovation as its core competitive advantage to drive the continuous upgrade of its TNC 2.0 modules. As a result, the company has continuously made breakthroughs in improving bifaciality, optimizing temperature coefficient, and enhancing power competitiveness, and further advanced the full lifecycle power generation efficiency and return on investment of modules, providing higher-value PV solutions for the global market.

The TNC 2.0 modules on display are fully equipped with the new generation of TNC 2.0 cells to achieve a leap in cell efficiency when compared with the first-generation products. By adopting the EPT edge passivation technology, steel plate printing, 908 cell interconnection technology, and Poly Tech technology, TNC 2.0 modules achieve higher bifaciality and create greater terminal returns. Among them, TNC-G12 boasts a maximum power of 765W and a module efficiency of 24.6%, while TNC-G12R boasts a maximum power of 670W and a module efficiency of 24.8%, making them lead in the sector.

Authoritative certification

Showing green and low-carbon strength

At the exhibition, Tongwei was granted the IEC TS 62994:2019 certification by TÜV Rheinland. This authoritative certification is based on the whole chain of modules' raw material selection, manufacturing, terminal applications, and waste recycling, with a rigorous assessment of its low-carbon and eco-friendly performance. Tongwei successfully passed the certification for its green manufacturing, clean energy applications, and efficient product design, further demonstrating its leading strength in the field of sustainable development and providing "Chinese solutions" for the green and low-carbon transformation of the global PV sector.

Deepening cooperation

Promoting Japan's green transformation

During the PV EXPO 2025, Tongwei carried out in-depth exchanges with numerous local customers, project developers, and distributors, exploring technological innovation, market trends, and the future prospects of Japan's PV sector.

The Japanese market mainly focuses on distributed PV, where customers are particularly concerned about the power generation efficiency and long-term reliability of modules within limited roof space. Many customers highly recognize the high-efficiency performance of TNC 2.0 modules and believe that the products have extremely high compatibility and competitiveness in residential, industrial, and commercial distributed application scenarios.

In the future, Tongwei will constantly enhance close cooperation with local distributors and partners in Japan and delve into and strive to market demands. Through continuous optimization of product performance and improvement of its service system, Tongwei will work hard to help realize higher power generation efficiency per unit area in Japanese distributed PV projects and provide sustained momentum for the local green and low-carbon transformation. By virtue of its profound technological accumulation and continuous innovative strength, Tongwei will keep contributing the Chinese wisdom to the advancement of global sustainable development and energy transition.
