JA Solar 455W JAM54D40 LB

JA Solar DeepBlue 4.0

The JA Solar JAM54D40 LB modules from the DeepBlue 4.0 series deliver 430–455W with high-efficiency Mono-PERC cells and 16 busbars. Featuring a bifacial double-glass structure and black frame, their half-cell design improves durability, minimizes shading losses, and maximizes energy output from both sides, combining top-tier performance with modern aesthetics.

Features:

1. Efficiency: 26% efficiency rate, leveraging advancements like 16-busbar and N-type technology.

2. Cost Efficiency: Lower Levelized Cost of Energy (LCOE), thanks to high efficiency and superior technology.

3. Durability: Improved mechanical loading tolerance.

4. Low Light Performance: Enhanced low irradiance response and very low Light Induced Degradation (LID).

5. Aesthetics: Sleek, all-black design suitable for diverse installation environments.
