CNBM SKT440M6 440W PERC Monocrystalline Bifacial Solar Panel
SKT440M6 | PERC Technology | 144 Half-Cells | Bifacial | 1500V System Voltage
Product Overview
The CNBM SKT440M6 solar panel delivers exceptional energy performance with 440W maximum power output. This monocrystalline module features advanced PERC technology for superior efficiency in low-light conditions. Its bifacial design captures sunlight from both sides, increasing total energy generation significantly. The panel boasts 20.2% module efficiency with 144 high-quality half-cut cells. Built for durability, it withstands mechanical loads up to 5400Pa on the front side. The anti-reflective coating maximizes light absorption while minimizing energy loss. Operating temperatures range from -40°C to +85°C for global climate compatibility. This robust solar solution is ideal for residential and commercial installations requiring reliable power. The 1500V maximum system voltage supports large-scale grid integration projects effectively.
Key Benefits
High Power Output: Generates 440W peak power for efficient energy production in standard conditions.
Bifacial Design: Captures sunlight from both front and rear surfaces to boost total energy yield.
PERC Technology: Enhanced cell efficiency improves performance in low-light and cloudy weather scenarios.
Superior Durability: Tempered glass and anodized frame resist extreme winds, snow loads, and corrosion.
Long Warranty Life: Includes 12-year product warranty and 25-year power warranty for lasting reliability.
How It Works
This solar panel converts sunlight into electricity using advanced photovoltaic cells. The PERC layer behind each cell reduces electron recombination for higher efficiency. Bifacial technology allows rear-side cells to capture reflected light from the ground surface. The half-cut cell design minimizes internal resistance and improves power output under partial shading. Double tempered glass protects internal components while maintaining optical clarity for maximum light transmission.
Photovoltaic Conversion: Sunlight hits 144 monocrystalline cells, exciting electrons to create direct current electricity. This process happens instantly with no moving parts required.
PERC Enhancement: The Passivated Emitter and Rear Cell layer captures unused light spectrum. This doubles the effective light absorption compared to standard cells.
Bifacial Generation: Rear-side cells absorb reflected light from white surfaces or grass. This increases total energy output by up to 25% in optimal setups.
