Data Sheet

JA Solar JAM72D42-620/LB (Deep Blue 4.0 Pro) – 620 W, N-Type Bifacial Glass-Glass

The JA Solar JAM72D42-620/LB is a 620 W N-type bifacial glass-glass module (144 cells — 6 × 24) engineered for high-yield commercial and utility installations. It delivers ≈22.18% module efficiency, supports 1500 V systems, uses 2.0 mm heat-strengthened front & back glass, and comes with 12 years product warranty and 30 years linear power warranty.

✅ Advantages for installers

Very high power — 620 W: More watts per module reduce BOS and installation costs per kWp.
High efficiency (~22.18%): Better energy yield per m² — ideal when roof/land area is limited.
Bifacial glass-glass construction: Rear-side generation on reflective surfaces increases total energy yield and improves mechanical durability.
Rugged mechanical ratings: Snow load 5,400 Pa / Wind load 2,400 Pa for reliable outdoor performance.
System-friendly electricals: Supports 1500 V systems; temperature coeff. Pmax −0.30%/°C and tight power tolerance (0 … +5 W) enable long strings and predictable output.
Installer-friendly connectors & cable options: Supplied with MC4-EVO2A connectors. Cable length depends on orientation / order options (e.g. ±1500 mm for landscape configuration or other variants such as 300/400 mm or 800/800 mm for different mounting/orientation choices) — specify the desired cable option when ordering.
