550W JA Solar Deep Blue 3.0 Bifacial Mono PERC Double-Glass Solar Panel
Overview
The JA Solar 550W Bifacial Deep Blue 3.0 (JAM72D30-550/MB) delivers maximum power density and long-term durability for high-yield solar installations. Equipped with 11-busbar PERCIUM half-cells and dual-glass construction, this panel captures direct sunlight from the front while absorbing ambient reflected light (albedo) from the rear.
With up to an additional 10–25% power boost from rear-side generation, total effective output can exceed 600W under optimal ground reflectivity. Built for demanding commercial, agricultural, ground-mount, and high-capacity residential setups, it significantly reduces Levelized Cost of Energy (LCOE) and balance-of-system (BOS) wiring expenses.
Key Features
-
Maximum Energy Yield (21.3% Front STC Efficiency): Reaches peak efficiency to optimize energy capture in limited space.
-
Bifacial Power Boost: 70% p/m10%) bifaciality rating allows the rear side to convert ambient light reflected off paving, gravel, or light roofing into extra current.
-
Extended 30-Year Performance Warranty: Double-glass encapsulation limits degradation to just 0.45% per year, guaranteeing long-term energy security.
-
30A Max Fuse Rating: Accommodates higher current flow from combined front and rear production without thermal bottlenecks.
-
Heavy-Duty Double-Glass Build: Dual 2.0mm semi-tempered glass layers provide superior protection against moisture, PID (Potential Induced Degradation), micro-cracks, and salt spray.
