On March 5, 2025, the 20th China (Jinan) International Solar Energy Utilization Conference and the 4th China (Shandong) New Energy and Energy Storage Application Expo were successfully held in Jinan, Shandong Province. At the event, Tongwei unveiled its TNC 2.0 new module to the domestic market for the first time, delivering an optimized solution for the distributed market with enhanced efficiency.

Expo Site

Recently, the National Development and Reform Commission, the National Energy Administration, and other authorities jointly issued the Notice on Deepening the Market-oriented Reform of New-Energy-Derived On-grid Electricity Prices to Promote High-Quality Development of New Energy. The Notice stipulates that grid-connected electricity generated from new energy sources shall be integrated into the power market, with its pricing regulated through market-based transactions. Every policy adjustment shapes market dynamics and guides the direction of sector development. The establishment of electricity transaction price will enable a more transparent reflection of PV power station revenues, further accentuating the competitive edge of high-efficiency PV plants.

At its core, electricity marketization revolves around the competition in cost per kilowatt-hour. Rather than putting a "restrictive spell" on the PV sector, it serves as an "accelerator" propelling the industry toward greater growth and innovation. High efficiency, reliability, and superior degradation control of PV modules are the elements underpinning the enduring profitability of power stations. Products that consistently deliver high returns hold greater value for customers and are more closely aligned with market demands.

TNC 2.0 Empowers Distributed Customers to "Lead" the Market

In an era of innovation and change, only enterprises with technological penetration across the entire industry chain can maintain vigorous vitality and achieve sustainable development. Through continuous innovation and refinement, Tongwei has excelled and optimized every facet of the industry chain, from silicon materials to cells and modules, realizing all-around performance enhancements. This enables our partners to grasp the direction of the times, stand resiliently at the cutting edge of a rapidly evolving market, and transform from "top performers in the subsidy era" to "pioneers in the market-driven era."

Tongwei TNC 2.0 Debut in Jinan

TNC 2.0 module series are comprehensively upgraded by the integration of advanced process design:

908 busbarless technology: using a low-temperature cell stringing process to minimize silver usage; optimized for thinner wafers, with lower cost of module auxiliary materials.

EPT passivation technology: addressing edge imperfections from cell cutting, enhancing the efficiency of half-cut cells and module power.

Steel plate printing technology: enabling ultra-fine line printing, improving efficiency while reducing silver paste usage.

Poly tech: ensuring passivation and contact performance, minimizing optical losses, and enhancing module power.

The synergy of these four innovative technologies fully unleashes the potential of the TNC 2.0 modules, expanding the boundaries of module efficiency. This leads to concurrent improvements in both module efficiency and bifaciality, establishing a strong foundation for future technological advancements and feature extensions. TNC-G12 utilizing the new TNC 2.0 technology currently reaches a maximum power of 765W with a conversion efficiency of 24.6%, while the TNC-G12R reaches up to 670W with a conversion efficiency of 24.8%.

Beyond deepening product performance to elevate customer power generation efficiency, Tongwei modules also prioritize on the scenario-specific needs of customers in practical applications. Catering to the unique features of various application scenarios, Tongwei has launched a range of specialized module products, refined and optimized the products based on mainstream specifications for their application in residential rooftops, industrial and commercial cement and color steel rooftops, and ground-mounted power stations. Moreover, the TNC 2.0 products reduce logistics costs by 3% and EPC costs by over 1.5%, saving the time and financial costs incurred by customers in the planning and construction of PV power stations, delivering tangible benefits. In the future, Tongwei will continue to uphold the product philosophy rooted in practical applications and customer needs, and persistently upgrade its modules in terms of design, power, and aesthetics to make them better adapt to more diverse application scenarios.

Advancement in Efficiency, Enrichment in Value

Amidst the exhibition, Tongwei with over ten strategic partners launched a signing ceremony to "Initiate the New Era and Mark the PV Path". This ceremony shows not only a strong bond of their cooperation but also a key stride towards mutual success in 2025. Looking ahead, Tongwei will persistently drive itself with innovation propellant, anchor itself in exceptional quality, and safeguard its commitment with superior service, working in concert with all partners to unlock the limitless potential of PV sector and compose a new chapter in the evolution of green energy.

Signing Ceremony

On the "8th China Distributed PV Conference" concurrently held with the expo, Tongwei was honored with "Top Ten Influential Brands of Distributed PV Modules in China". The distributed PV market is currently facing a critical shift from "scale expansion" to "efficiency supremacy". Tongwei TNC modules have gained global popularity and won the top spot in domestic distributed shipments in 2024. On this solid groundwork, Tongwei continuously strives for progress by leveraging its production and research strength to advance, transform and elevate the efficiency of its module products, thereby delivering greater value to the distributed sector.
