JA Solar JAM54D40-445/LB – High-Efficiency n-type Solar Module for Maximum Yields

The JA Solar JAM54D40-445/LB embodies the perfect balance between power and efficiency. With impressive 445 Wp rated power and 22.3% module efficiency, this bifacial double-glass module belongs to the top class of the Deep Blue 4.0 Pro series and is excellently suited for demanding solar projects.

Premium n-type Cells for Superior Performance

The JAM54D40-445/LB uses 108 highly selected n-type half-cells with nBycium+ technology. These advanced cells achieve up to 26% efficiency at cell level and are characterized by particularly low LID and excellent low-light performance. Even in diffuse light conditions, the module delivers consistently high yields.

Bifacial Technology for Additional Yield

The transparent rear side of the JA Solar JAM54D40-445/LB enables the use of reflected light with a bifaciality of 80%. Depending on the ground and mounting, an additional 5 to 15 percent energy yield can be generated. The glass-glass construction provides optimal protection and ensures an exceptionally long service life.

Technical Excellence in Every Detail

With an open-circuit voltage of 39.10 V and a current at maximum power of 13.63 A, the module is optimized for modern string inverters. The connection cables with 4 mm² cross-section and high-quality QC 4.10-351 or MC4-EVO2A connectors guarantee secure and low-loss connections.

Reliability Made by JA Solar

The quality management system according to IEC 62941:2019 ensures the highest manufacturing standards. Each JAM54D40-445/LB module undergoes strict quality controls and is delivered with a 25-year product warranty and 30-year linear performance guarantee. The NOCT of 45°C shows the balanced thermal behavior.
