Recently, KiwaPVEL (hereinafter referred to as PVEL), the world's leading photovoltaic module reliability and performance testing laboratory, released the 2025 Photovoltaic Module Reliability Scorecard.
In the published test results, Tongwei TNC component has achieved the best performance in the full reliability test sequence, which proves that the reliability of Tongwei TNC component not only meets the IEC standard, but also meets the IEC standard. It meets the reliability requirements of various extreme harsh environments and intuitively demonstrates the excellent reliability and performance advantages of Tongwei components.
Tongwei has also become one of the only two TOP10 module manufacturers that have passed seven excellent reliability tests of photovoltaic modules and won the honor of "Best Module Manufacturer" of PVEL in 2025. This is the second consecutive year that Tongwei has won this honor since it fully entered the component business.
PVEL simulates the reliability performance of modules under different extreme environmental conditions through rigorous tests higher than IEC certification standards every year, which is an important basis for measuring the long-term reliability and performance of photovoltaic modules in the industry. PVEL tests
in 2025 include TC600, DH2000, PID192, LeTID486, MSS (mechanical stress), HSS (hail test (40mm)), Panfile 7 test sequences, and a new UV120 test sequence.
On the basis of continuous verification of reliability performance of TNC components, Tongwei is also moving towards higher efficiency and higher value. The TNC 2.0 component released
by Tongwei in 2025, based on the four core technologies of 908 technology (0BB technology independently developed by Tongwei), TPE technology, Poly Tech and steel mesh printing, fully unlocks the potential of N-type components and broadens the efficiency boundary of components. It realizes the synchronous improvement of component efficiency, power and double-sided rate, and lays a solid foundation for subsequent technology iteration and function expansion.
