6X JA 590w Tier 1 Bifacial Mono Solar Panel (JAM72D40-590/MB) 

(Courier for panels are at your own risk)

The JA Solar JAM72D40-590/MB is a high-power 72-cell monocrystalline module with a 16-busbar layout, delivering 590 Wp and a module efficiency of ≈22.8%, with a tight power tolerance of 0 / +5 W and a temperature coefficient of −0.30%/°C.
Designed for commercial and utility-scale projects, it features low degradation (~1% first year; ~0.40% p.a. thereafter) and an industry warranty package (12 years product workmanship / 30 years power warranty), making it a reliable choice for high-density PV installations.

 High per-module output — 590 Wp: reduces BOS and mounting costs per installed kWp.
• Efficient cell layout — 16-busbar / 144 cells: improved current collection and lower series resistance for better real-world yield.
• Good module efficiency — ~21.8%: maximizes energy per m² and is excellent for constrained roof/ground space.
• Tight power tolerance — 0 ~ +5 W: predictable string design and simpler binning for large projects.
• Low degradation & long warranty: 1% first year and ~0.40% annual degradation with 12 y product + 30 y power warranty lowers lifecycle risk.
• Installer-friendly electrical spec: conservative temperature coefficient (~−0.30%/°C) supports stable output in hot climates.
• B2B advantages: high power density and reliable warranty make it a strong choice for commercial and utility procurements.
