545W JA Solar Deep Blue 3.0 Bifacial Mono PERC Double-Glass Solar Panel
545W JA Solar Deep Blue 3.0 Bifacial Mono PERC Double-Glass Solar Panel
Overview
Maximize your energy yield per square meter with the JA Solar 545W Bifacial Deep Blue 3.0 module. Featuring advanced Mono PERCIUM 11-busbar half-cells combined with a dual-glass construction, this panel captures sunlight from both sides—converting direct rays on the front and reflected light (albedo) off surfaces like white roofs, gravel, or paving on the back.
With up to an additional 10–25% power gain from the rear side, this bifacial unit significantly lowers the Levelized Cost of Energy (LCOE), making it ideal for ground mounts, flat commercial roofs, carports, and high-yield off-grid setups.
Key Features
-
Bifacial Power Generation: Dual-glass design absorbs reflected ground light, boosting total effective power well beyond 545W depending on surface reflectivity.
-
30-Year Performance Guarantee: Upgraded double-glass encapsulation slows aging to just 0.45% annual linear degradation, backed by an extended 30-year output warranty.
-
High Efficiency (21.1% Front STC): Top-tier efficiency rating ensures high output density.
-
Enhanced Environmental Protection: Double 2.0mm tempered glass provides superior resistance against moisture, salt mist, PID (potential induced degradation), and micro-cracking.
-
1500V DC System Compatibility: Allows for longer string configurations, lowering overall balance-of-system (BOS) wiring costs.
