JA Solar 460W JAM54D40 Bifacial Glass-Glass Black Frame

JA Solar 460W JAM54D40 LB All Black MC4

High Performance and Efficiency

The JA Solar 460W solar module is based on advanced N-Type mono-cell technology and achieves a maximum efficiency of 22.8%. With its optimized cell architecture, it delivers strong performance even in low light conditions—ideal for diffuse lighting in the morning, evening, or during cloudy weather. The positive power tolerance of up to +5 W ensures stable energy yields and reliable power production throughout its lifespan.

Durability and Longevity

The JA Solar 460W module is designed for longevity—with a linear performance warranty over 30 years. The initial degradation is less than 1%, and thereafter, the performance decreases by only about 0.4% annually. The bifacial glass structure provides excellent protection against moisture, PID, and mechanical stress, ensuring stable module performance over decades.

Versatile Applications

Thanks to the bifacial glass-glass technology, the module can generate up to 20% additional energy from the rear side. It is therefore ideal for ground-mounted systems, carports, or flat roofs with reflective surfaces. With a temperature coefficient of -0.29%/°C, performance remains consistent even at high ambient temperatures. The module withstands wind loads up to 2400 Pa and snow loads up to 5400 Pa.
