Key Features
-
Tier-1 Reliability: Manufactured by JA Solar, a global leader recognized for high-bankability and rigorous quality standards.
-
Bifacial Energy Gain: The double-glass construction enables rear-side power generation, potentially increasing total energy yield by up to 25% on reflective surfaces.
-
Advanced N-Type TOPCon Technology: Utilizes SMBB (Super Multi-Busbar) to minimize current loss and provide a better temperature coefficient for performance in hot climates.
-
Exceptional Efficiency: Reaches an impressive 22.8% module efficiency, allowing you to generate more power with fewer panels.
-
Superior Durability: Features a 2.0mm dual-glass structure that provides enhanced protection against environmental stress and zero Light Induced Degradation (LID).
-
High-Temperature Performance: Optimized to maintain stable power output even during peak afternoon heat, thanks to its low temperature coefficient.
