CiFi SUN 66HL4M-BDV 640W N-Type TOPCon Bifacial Solar Panel
66HL4M-BDV | N-Type TOPCon | 132 Mono-Crystalline Cells | Bifacial | 1500V System Voltage
Product Overview
The CiFi SUN 66HL4M-BDV 640W N-Type TOPCon Bifacial Solar Panel delivers exceptional energy performance for modern solar installations. This high-efficiency module features advanced N-type TOPCon technology to minimize degradation and maximize low-light output. Its bifacial design captures sunlight from both sides, significantly reducing the levelized cost of energy. The panel operates reliably in temperatures ranging from -40°C to 70°C. With a robust 640W peak power and 23.69% efficiency, it is ideal for large-scale commercial projects or residential rooftops. The dual-glass construction ensures enhanced mechanical load resistance and long-term durability. A 12-year product warranty and 30-year performance warranty guarantee sustained power output over decades. This solar panel combines cutting-edge engineering with proven reliability for superior energy generation.
Key Benefits
Advanced N-Type TOPCon Technology: This technology reduces light-induced degradation and improves low-light performance for consistent energy output.
Bifacial Dual-Sided Generation: Captures sunlight from the rear side to increase total power generation and lower overall energy costs.
Enhanced Mechanical Load Resistance: Certified to withstand 5400 Pa front load and 2400 Pa rear load for extreme weather durability.
Superior Temperature Performance: Low temperature coefficient of -0.29%/°C ensures stable power output even in high-heat conditions.
Long-Term Warranty Protection: Includes a 12-year product warranty and a 30-year linear power warranty guaranteeing 87.4% output.
How It Works
This solar panel converts sunlight into electricity using advanced photovoltaic cells. The N-type TOPCon technology creates a tunnel oxide passivating contact layer that reduces electron recombination. This process allows more electrons to flow freely, increasing the overall efficiency of the module. The bifacial design enables the panel to capture light from both the front and rear surfaces. Rear-side exposure to reflected light significantly boosts power generation compared to traditional monofacial panels. The dual-glass structure protects the internal cells from environmental stress and mechanical damage. This robust construction ensures the panel maintains high performance over its 30-year operational lifespan.
TOPCon Electron Trapping: The tunnel oxide layer traps electrons effectively, reducing energy loss and improving current collection efficiency.
Bifacial Light Harvesting: Light reflected from the ground or surrounding surfaces enters the rear glass, adding extra power to the total output.
SMBB Current Collection: Multi-busbar technology improves light trapping and reduces resistance, leading to higher module power output and reliability.
