DAS Solar has received its first UVID certification from TÜV Rheinland, based on the 2 PfG 2944/07.23 standard, not only highlighting the company’s leadership in UVID resistance for N-type modules, but also marking a significant milestone in its advancement in reliability testing.
Ultraviolet-induced degradation (UVID) refers to the power loss that occurs when PV modules are exposed to UV radiation over an extended period outdoors. As N-type TOPCon becomes the dominant high-efficiency cell technology and widely adopted across a variety of applications, the long-term stability of modules under strong UV conditions has become a focal point. To better characterize the performance of N-type high-efficiency modules under extreme UV environments, TÜV Rheinland has developed the 2 PfG 2944/07.23 standard based on IEC certification guidelines, simulating strong UV exposure scenarios to assess modules’ power stability and resistance to degradation in such conditions.
The certification is a significant recognition of DAS Solar’s UV resistance technology, paving the way for entering extreme application markets, such as high-altitude and desert regions with high UV radiation.
