625W JA Solar N-Type TOPCon Bifacial Double-Glass
Overview
Maximize your energy yield and lower your Levelized Cost of Energy (LCOE) with the JA Solar 625W Bifacial Solar Panel (JAM66D45 LB). Built with high-performance N-Type TOPCon cell architecture and multi-busbar (MBB) half-cell engineering, this module delivers an exceptional 23.1% overall panel efficiency with cell conversion rates reaching up to 26%.
Its dual-sided (bifacial) configuration generates power from direct overhead sunlight while simultaneously harvesting light reflected onto the rear side from surrounding surfaces. Designed for maximum long-term reliability, N-type technology virtually eliminates initial Light-Induced Degradation (LID), while an optimized temperature coefficient ensures strong power output even during high ambient heat conditions.
Key Highlights
-
23.1% Module Efficiency: High power density powered by N-Type TOPCon cells with multi-busbar (MBB) design to minimize internal resistance.
-
Bifacial Energy Yield: Harvests secondary sunlight reflected off ground or roof surfaces, significantly boosting overall daily kWh production.
-
Minimal LID & PID Degradation: N-type silicon construction prevents severe initial power loss, ensuring a high 99% baseline output after Year 1.
-
Enhanced Thermal & Low-Light Performance: Maintains higher relative efficiency during cloudy days, early mornings, and high-heat peak summer months.
-
30-Year Performance Backing: Covered by a 12-year product workmanship warranty and a 30-year linear performance guarantee down to 87.4% output.
