JA Solar 595W JAM66D42 MB

JA Solar DeepBlue 4.0

The JA Solar JAM66D42 MB modules from the DeepBlue 4.0 series feature high-efficiency Mono-PERC cells with a 16-busbar design, delivering 570–595W per panel and maintaining strong performance in low-light conditions. The N-type bifacial double-glass structure captures sunlight from both sides, boosting energy output. A half-cell layout reduces hot spots, stress, shading, and resistive losses for enhanced durability. With an all-black design and mid-mounted split junction box, these modules offer both sleek aesthetics and flexible installation.

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.
