Combining Global Vision with Local Efforts

The Efficiency Relay from Munich to Yantai

As a key component of Tongwei's global strategy, the TNC 2.0 product made its debut at Intersolar Europe 2025, attracting significant international attention. From Europe's industrial heartland to China's coastal gems, TNC 2.0's global footprint embodies Tongwei's vision of "PV Changing the World". The Yantai event focused on upgrading China's distributed PV sector, aligning with the trend of green power marketization to further refine technology implementation scenarios and deliver "value-optimized solutions" for the market of distributed PV.

Speech by Sun Zhiyang, Head of Distributed PV Business in Module Marketing 

at Tongwei Co., Ltd.'s PV Business Department

Sun Zhiyang, Head of Distributed PV Business in Module Marketing at Tongwei Co., Ltd.'s PV Business Department, stated that the high efficiency, high reliability, and superior attenuation control of PV modules form the foundation for the long-term profitability of power stations. Only stable high-yield products can deliver greater value to customers, thereby more precisely meeting market demands. Tongwei consistently drives performance evolution through technological innovation. The TNC 2.0 product represents a milestone achievement from Tongwei's deep technical expertise and iterative upgrades.

Market analysis of distributed PV

Qu Saisai, Senior Market Analyst at Tongwei Co., Ltd.'s PV Business Department, highlighted in Distributed Market Trends Under China's Energy Transition that China's policies promote PV consumption, encourage distributed PV to engage in electricity market trading, and implement renewable energy substitution initiatives. At the regional level, multiple provinces are exploring projects like direct green electricity supply and zero-carbon industrial parks to advance the energy transition. With the full marketization of electricity, the consumption of new energy power and the green, low-carbon transition have become dual priorities for both policy and market. PV plant profitability will become more transparent, while modules—as the core power generation component—will see their high-efficiency and high-yield advantages further amplified.

Technology as the Core, Scenarios as the Wings

TNC 2.0 Injects New Momentum into Distributed PV

Witnessed by attendees, Tongwei's TNC 2.0 module was officially unveiled.

During the launch, the personal avatars uploaded by all the guests were combined in real-time through a large screen, converging into the brand logo of Tongwei TNC 2.0—symbolizing the company's concept of co-creation and co-advancement. This demonstrates Tongwei's commitment to collaborating with partners in elevating PV technology and injecting robust momentum into global green energy initiatives, ushering in a new era of performance evolution.

Powered by four core technologies—908 Technology (Tongwei's independently developed 0BB technology), TPE Edge Passivation, Poly Tech, and steel screen printing—TNC 2.0 fully unlocks the potential of N-type modules, broadens the efficiency boundaries of modules, and achieves simultaneous improvements in module efficiency, power, and bifaciality. Moreover, it establishes a solid foundation for future technological iterations and functional expansions.

Decoding TNC 2.0's performance evolution

He Song, Senior Technical Engineer for Module Marketing Support at Tongwei Co., Ltd.'s PV Business Department, used the event venue Chateau Changyu as a case study: If TNC 2.0 modules are fully adopted, the power stations with original installed capacity of 800kW and 2MW can increase their capacity by 117kW and 65kW, respectively, under the same area, bringing a 14.6% and 3.2% increase in power generation, realizing a double increase in installed capacity and power generation.

Transitioning from a "frontrunner under subsidies" to a "market leader", Tongwei's TNC 2.0 is poised to provide robust support for long-term power plant returns amidst the distributed PV transformation through high efficiency, high reliability, and superior degradation control.

Keynote speech by Wang Shujuan, Founder of Zhihui PV

Wang Shujuan, Founder of Zhihui PV, noted that future distributed PV projects will closely align with load requirements. Pre-implementation assessments must evaluate enterprise creditworthiness and long-term electricity stability. During operation, the comprehensive electricity price for self-use portions will dynamically adjust with the grid's peak and valley periods, while feed-in tariffs will be subject to market trading prices. To mitigate future uncertainties, a more stable investment strategy involves reducing initial investment and shortening the payback period while ensuring the quality of distributed PV projects.

The reliability of TOPCon technology has been proven through large-scale application across the industry. TNC 2.0 modules, with their system cost advantages and high initial yield capabilities, can help projects achieve higher net profits in the early stages of operation, rapidly reaching peak profitability and ensuring stable project returns.

Higher efficiency, exceptional power generation capacity, and superior quality

are the hallmarks of Tongwei TNC modules.

Tongwei TNC 2.0 modules

represent an evolution in performance, taking it a step further.
