TONGWEI has been named as an "Overall Highest Achiever"in RETC’s 2026 PV Module Index Report (PVMI), receiving the report’s highest honor for outstanding results across reliability, performance, and quality evaluations. The award underscores the exceptional durability and comprehensive performance of TONGWEI’s TNC modules.
As one of the industry’s leading independent testing organizations, RETC evaluates PV modules through its PV Module Index Report, which features testing protocols that go beyond standard IEC certification requirements. Covering three key dimensions — Reliability, Performance, and Quality — the assessment examines critical factors such as power degradation, mechanical durability, thermal stability, and long-term operational performance.
The “Overall Highest Achiever” title is granted only to products that demonstrate outstanding performance across all three evaluation categories. Among global manufacturers participating in the 2026 PV Module Index Report, TONGWEI’s TNC modules achieved this highest honor, proving their ability to deliver consistent performance and reliability under demanding operating conditions.
This achievement reflects TONGWEI’s commitment to integrating quality and reliability throughout every stage of product development and manufacturing. Through continuous technology innovation, advanced manufacturing capabilities, and strict quality management systems, TONGWEI ensures that its modules can withstand diverse environmental challenges while maintaining stable long-term energy generation.
Building upon this proven track record of reliability, TONGWEI continues to advance photovoltaic technology with its latest TNC 3.0 module series. Designed with innovative cell and module technologies, TNC 3.0 delivers higher power output, improved conversion efficiency, and enhanced energy yield for a wide range of applications. The series achieves a maximum power output of 770W and module efficiency of up to 24.8%, helping customers maximize project returns and reduce the levelized cost of electricity (LCOE).
With recognition from internationally respected testing institutions and continuous breakthroughs in PV technology, TONGWEI remains dedicated to providing reliable, high-performance solar solutions that accelerate the global transition toward a cleaner energy future.
