Trinasolar’s Vertex N 720W modules have excelled in a stringent UV test with an industry-leading degradation of 1.6% after being exposed to 300kWh/m² of frontal UV irradiation (UV300), tested and certified by the China General Certification Center. This underlines once again its great reliability and the competitiveness of Trinasolar products.
Power Degradation VS Cumulative UV Exposure
The performance of PV modules under UV irradiation is critical for their long-term reliability, so an increasing number of organizations are adopting rigorous UVID tests for PV modules. The CGC’s UV300 test is conducted with about 20 times the exposure required for IEC basic UV certification (UV 15), and according to authoritative organizations is estimated to be equal to four years of field UV exposure.
For Trinsolar’s tested module, the EL images show that the cells have no visible defects, and the performance of each module cell is highly consistent after the UV300 test. Furthermore, the modules passed both insulation and wet leakage tests following each UV test cycle, further validating the exceptional UV attenuation performance of Trinasolar Vertex N modules.

RETC has included UVID in its thresher test for the first time in PVMI this year. In the UVID category, PV module samples withstand UV220 exposure with less than 2% degradation in maximum power. Trinasolar Vertex N 625W module is one of only two modules meeting RETC’s UVID high achiever criteria. It shows 1.53% and 0.94% degradation, respectively, in the front and back after the UVID test.
“Trina has had the lowest degradation rates of any manufacturers we tested this year, so your product has done amazingly well,” said RETC’s chief executive and president, Cherif Kedir in June 2024.
Trinasolar’s position as a trusted market leader has been reinforced since its Vertex N series, based on n-type i-TOPCon advanced technology and the 210mm product technology platform and including both large- and medium-format modules, has passed rigorous UV tests, further affirming its great reliability.
“Great product reliability reflects not only technical excellence but also a commitment to customer experience and social responsibility,” said Trinasolar’s head of global branding and marketing, Cao Yunduan. “Trinasolar remains steadfast in implementing rigorous quality controls during the R&D phase to maximize customer value.”
Trinasolar will continue to use cutting-edge technology to create exceptional products and to bring about a net-zero world.
