CiFi SUN 66HL4M-BDV 635W N-Type TOPCon Bifacial Solar Panel
66HL4M-BDV | N-Type TOPCon | 132 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The CiFi SUN 66HL4M-BDV 635W N-Type TOPCon Bifacial Solar Panel represents the pinnacle of modern photovoltaic innovation. This high-performance module utilizes advanced N-type monocrystalline cells with Tunnel Oxide Passivating Contacts technology. It delivers exceptional energy generation with a maximum power output of 635 Watts. The bifacial design captures sunlight from both sides, significantly reducing the Levelized Cost of Energy. Its robust dual-glass construction ensures superior durability against harsh environmental conditions. The panel achieves an impressive module efficiency of 23.51 percent. This makes it ideal for large-scale commercial installations and demanding residential projects. It operates reliably in temperatures ranging from -40 to 70 degrees Celsius. The product includes a 12-year warranty and a 30-year linear power performance guarantee. Users benefit from minimal degradation over its long operational lifespan.
Key Benefits
Bifacial Power Generation: Captures sunlight on both front and rear surfaces to boost total energy yield by up to 25 percent.
N-Type TOPCon Technology: Reduces light-induced degradation and ensures superior performance in low-light conditions compared to traditional panels.
Enhanced Mechanical Load: Supports front static loads of 5400 Pa and rear loads of 2400 Pa for extreme weather resistance.
Long-Term Warranty: Guarantees 12 years of product protection and 30 years of linear power output with only 87.4 percent degradation.
High Efficiency Rating: Delivers 23.51 percent module efficiency, maximizing power output per square meter of installation space.
How It Works
This solar panel operates by converting sunlight into electricity using advanced N-type monocrystalline silicon cells. The unique TOPCon technology creates a passivating layer that minimizes electron loss during energy conversion. This process significantly reduces degradation caused by light exposure over time. The bifacial design allows the panel to absorb reflected light from the ground on its rear side. This dual-sided absorption increases total power generation and lowers overall system costs effectively. The dual-glass construction protects internal components from moisture and physical stress. It ensures the module maintains high efficiency even in extreme temperature fluctuations. The integrated junction box safely manages the electrical output for connection to inverters.
TOPCon Passivation: The Tunnel Oxide Passivating Contact layer prevents electron recombination, improving current collection efficiency. This results in lower degradation rates and better low-light performance than standard panels.
Bifacial Absorption: Light hitting the rear glass generates additional electricity, especially when installed over reflective surfaces like white gravel. This dual-sided gain significantly reduces the Levelized Cost of Energy for the project.
SMBB Technology: Super Multi-Busbar technology uses more busbars to trap light better and collect current more efficiently. This improves the overall module power output and enhances long-term reliability.
