JA Solar JAM54D40-445/LB (Deep Blue 4.0 Pro) – 445 W, n-type bifacial glass-glass

The JA Solar JAM54D40-445/LB is a 445 Wp n-type bifacial glass-glass module engineered for high areal yield and long-term reliability. It features a 108 half-cell layout, a module efficiency of ≈22.3%, robust mechanical ratings (snow 5,400 Pa / wind 2,400 Pa) and is offered with a 25-year product warranty (LB glass-glass) plus a 30-year linear performance warranty.

✅ Advantages for installers

High power density – 445 Wp: More energy per module reduces BOS cost and required area.
Bifacial glass-glass construction: Rear-side generation increases total yield on reflective surfaces and improves mechanical durability.
n-type cells: Lower LID and strong long-term performance as stated by the manufacturer.
Robust mechanical specs: Certified for heavy snow and wind loads suitable for commercial and rooftop installations.
Exact connector & cable options: Supplied with QC 4.10-351 / MC4-EVO2A family connectors; portrait and landscape cable length variants are available to match mounting orientation.
Long warranties: 25 years product warranty (LB glass-glass) and 30 years linear performance warranty for planning security.
