The JAM66D45 is part of JA Solar’s premium “Power Paragon” series, incorporating the latest Bycium+ N-type heterojunction technology. This 66-cell module delivers a maximum power output of 455W and achieves an impressive cell conversion efficiency of up to 25.3%. Designed for maximum energy generation and long-term value, it combines cutting-edge cell technology with robust module construction.

Key Features & Benefits:

Advanced N-Type Technology: The Bycium+ N-type cells provide higher efficiency, better low-light performance, and significantly lower power degradation compared to conventional P-type modules. The module maintains over 92% of original power output after 30 years.

Exceptional Bifacial Performance: With a bifaciality factor of 65±5%, the rear side captures reflected sunlight, generating up to 30% additional energy depending on ground conditions (e.g., grassland, snow, high-reflectivity surfaces).

Superior Reliability with Double-Glass Construction: The frameless design with two layers of 2.0mm tempered glass ensures exceptional resistance against moisture ingress, PID (Potential Induced Degradation), sand erosion, and harsh weather. It carries a 30-year linear power warranty and a 30-year product warranty.

Optimized Temperature Coefficient: A low temperature coefficient of -0.29%/°C minimizes power loss in high-temperature environments, ensuring more stable and reliable output during hot days.

Enhanced Durability & Safety: The module withstands high wind loads (up to 6000Pa) and snow loads (up to 5400Pa). Its fire-resistant construction meets stringent international safety standards.
