Empirical Evidence Highlights Power Generation Advantages

TÜV Rheinland is recognized as one of the most rigorous and impartial quality and performance testing and certification organizations in the global photovoltaic industry. The selection of the "PV Module Outdoor Energy Yield AQM Award" is based on detailed, long-term, and rigorous outdoor empirical data, which truly reflects the actual power generation capacity and durability performance of the product in complex natural environments.

In 2024, TÜV Rheinland randomly selected samples from Tongwei's mass-produced modules and sent them to Germany to participate in a one-year outdoor power generation performance evaluation. In test results, Tongwei's TNC G12-66 high-efficiency module outperformed competing bifacial modules from leading enterprises with absolute power generation superiority, securing the "PV Module Outdoor Energy Yield AQM Award 2025". This validates Tongwei PV modules' exceptional efficiency, superior low-light response, and stable performance under harsh conditions, directly delivering higher energy yields and superior ROI for customers. Xue Qingsong, Vice President of Marketing at Tongwei Co., Ltd., accepted the award on behalf of the company.

Tongwei TNC Modules Win

"PV Module Outdoor Energy Yield AQM Award 2025"

The awarding of the "All Quality Matters" award goes far beyond a simple honor. It vividly interprets the core mission of this industry event: to use the authoritative third-party perspective, through the "measured data" this hard yardstick, to identify the real technology benchmarks with long-term value and reliable quality in the complex market.

Technological Evolution, Continuously Ascending Value

The fact that Tongwei TNC modules can win this honor is inseparable from years of advantageous technology accumulation. Based on the continuous verification of the customer value performance of TNC modules, Tongwei is constantly moving towards higher efficiency and higher value. In 2025, Tongwei released the TNC 2.0 modules, based on the four core processes of 908 technology (Tongwei's independently developed 0BB technology), TPE technology, Poly Tech, and stencil printing, fully unlocking the potential of N-type modules.

TW Solar's intelligent manufacturing production line

Certified by TÜV Rheinland and CGC, the bifaciality of Tongwei TNC 2.0 modules reaches 88% + at the technology research and development level, which is 5-10 percentage points higher than the bifaciality of conventional TOPCon modules in the market, effectively improving the overall power generation and having better power generation performance.

The high bifaciality of TNC 2.0 modules combined with excellent weak light power generation performance has obvious power generation advantages in the early morning and evening. In the open array scenarios of centralized large-scale ground power stations, the significant improvement of system power generation can be achieved by virtue of the high bifaciality, and this advantage is continuously amplified with the enhancement of ground reflectivity, which can create long-term, stable, and higher value returns for customers.

Manufacturing Lighthouse, Delivering Greater Stability

TW Solar Meishan Company

As the real value of the product is verified, Tongwei continuously strengthens the system guarantee on the manufacturing side. The combination of the two forms a comprehensive competitiveness throughout the entire chain. In September this year, TW Solar Meishan Company was awarded the world's first "Lighthouse Factory" in the photovoltaic cell industry, which reflects the value of modules not only in power generation, but also in the long-term stability and quality assurance of the source manufacturing process. It has achieved a leap in efficiency improvement, process consistency and sustainable development, providing customers with "more stable, more punctual, and more verifiable" value delivery.
