JA Solar Deep Blue 4.0 Pro JAM72D40-590/LB Solar Module 590 Watt Silver/white Bifacial Glass-Glass 12 Years Product Warranty

The JA Solar JAM72D40-590/LB is a bifacial glass-glass solar module built with monocrystalline half-cell technology, delivering 590 Wp with a module efficiency of ≈22.3%. It measures 2333 × 1134 × 30 mm, weighs 32.6 kg, supports 1500 V DC system voltage, and offers reliable durability with mechanical load ratings of 5400 Pa front / 2400 Pa back. The module comes with a 12-year product workmanship warranty and a 30-year linear power warranty (≤1% first-year degradation, then ≤0.40% per year).

 • High power output — 590 Wp: reduces BOS and installation costs per installed kWp.
• Bifacial glass-glass design: rear-side generation boosts total system yield depending on site albedo.
• Solid efficiency — ~22.3%: strong energy density for large-scale and commercial projects.
• Robust mechanics: rated for 5400 Pa snow and 2400 Pa wind for long-term reliability.
• Stable thermal behaviour: low temperature coefficient (Pmax −0.30%/°C) ensures dependable output in hot climates.
• Installer-friendly: IP68 junction box, MC4-compatible connectors and 4.0 mm² pre-wired cables.
• Long-term reliability: 12 y product warranty and 30 y power warranty lower risk and ensure predictable yields.
