CiFi SUN 66HL4M-BDV 645W N-Type TOPCon Bifacial Solar Panel
66HL4M-BDV | N-Type TOPCon | 132 Mono-Crystalline | Bifacial | 1500V System Voltage
Product Overview
The CiFi SUN 66HL4M-BDV 645W N-Type TOPCon Bifacial Solar Panel delivers exceptional energy performance for modern solar power systems. This advanced monocrystalline module features N-type technology with Tunnel Oxide Passivating Contacts (TOPCon) to minimize degradation and maximize low-light efficiency. The dual-glass bifacial design captures sunlight from both sides, significantly reducing the Levelized Cost of Energy (LCOE). With a peak output of 645W and 23.88% efficiency, it is ideal for residential and commercial installations. The panel includes a robust anodized aluminum frame and an IP68-rated junction box for superior durability. A 12-year product warranty and 30-year linear power warranty ensure long-term reliability. Operating between -40°C and 70°C, it withstands harsh environmental conditions. This high-efficiency panel is engineered for maximum power output and minimal maintenance requirements.
Key Benefits
Bifacial Power Generation: Captures sunlight from both front and rear sides to increase total energy yield and reduce LCOE.
N-Type TOPCon Technology: Utilizes advanced tunnel oxide passivating contacts to lower LID/LeTID degradation and improve low-light performance.
Enhanced Mechanical Load: Certified to withstand 5400 Pa front load and 2400 Pa rear load for superior durability in extreme weather.
SMBB Technology: Features multi-busbar design for better light trapping and current collection to boost module power output.
Anti-PID Guarantee: Minimizes degradation from potential induced degradation through optimized cell production and material control.
How It Works
The CiFi SUN 66HL4M-BDV operates using advanced N-type monocrystalline cells with TOPCon technology. This design allows electrons to flow more efficiently, reducing energy loss during conversion. The bifacial structure captures reflected light from the ground on the rear side, increasing total power generation. The dual-glass construction protects internal components from moisture and physical damage. High-efficiency busbars collect current effectively to maximize output. Temperature coefficients ensure stable performance even in hot climates. The IP68 junction box maintains electrical safety under wet conditions. This system optimizes energy harvest for maximum return on investment.
Dual-Sided Power Generation: The panel captures sunlight from the front and rear surfaces simultaneously. This dual exposure significantly increases total energy yield compared to traditional single-sided modules.
TOPCon Cell Efficiency: Tunnel Oxide Passivating Contacts reduce electron recombination at the cell surface. This results in lower degradation rates and better performance in low-light conditions.
SMBB Current Collection: Multi-busbar technology improves light trapping within the cell structure. This enhances current collection efficiency and boosts overall module power output.
