JKM495-520N-51QL6-BDV
N-Type TOPCon Bifacial Dual Glass Module | 495-520W | 85% Bifaciality
The JKM495-520N-51QL6-BDV is a high-performance N-type bifacial module with dual glass construction, delivering 495W to 520W on the front side with an industry-leading 85±5% bifaciality factor. This means significant additional energy yield from the rear side under real-world conditions.
Built on JinkoSolar's enhanced N-type TOPCon platform, it features optimized heat resistance, proven low-light performance, and advanced metallization for superior PID/LID/LeTID resistance. The module is certified to withstand 5400 Pa front and 2400 Pa rear mechanical loads.
With up to 24.06% module efficiency and a 30-year linear power warranty, this module is ideal for utility-scale, commercial, and ground-mounted solar installations where maximizing energy density is critical.
