Greensun Solar GSM550-144 550W N-Type Bifacial Bifacial Solar Panel
GSM550-144 | N-Type Half-Cut | 144 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Greensun Solar GSM550-144 550W N-Type Bifacial Solar Panel delivers exceptional energy output for modern solar installations. This high-performance module features advanced N-Type technology with 144 half-cut cells to maximize efficiency and reduce power loss. Its bifacial dual-glass design captures sunlight from both sides, significantly boosting total yield in open areas. The panel achieves a remarkable 21.4% efficiency rating, ensuring more power per square meter compared to standard monocrystalline options. Built with rugged durability, it withstands harsh environmental conditions including salt mist, ammonia, and extreme temperatures. The black frame enhances aesthetic appeal while providing robust structural support for residential and commercial projects. This versatile unit supports a maximum system voltage of 1500V, making it ideal for large-scale grid-tied systems. Greensun Solar Energy Tech Co., Ltd manufactures this premium product with strict quality control processes to ensure reliability. Its optimized performance reduces hotspot risks and extends the overall lifespan of your solar investment. Homeowners and businesses can trust this panel for consistent, long-term energy generation with minimal maintenance requirements.
Key Benefits
High Efficiency Output: Achieves 21.4% module efficiency to generate 550W of power from limited space.
Bifacial Energy Capture: Dual-glass design captures sunlight on both sides to increase total energy yield significantly.
Advanced N-Type Technology: Uses N-Type half-cut cells to reduce power loss and improve long-term degradation rates.
Extreme Durability: Resists salt mist, ammonia, and harsh weather while preventing snail trails and hotspots effectively.
Aesthetic Black Frame: Features a sleek black frame that blends seamlessly with modern residential and commercial roofs.
How It Works
The Greensun Solar GSM550-144 panel converts sunlight into electricity using advanced photovoltaic principles. Sunlight strikes the N-Type half-cut cells, exciting electrons to create a direct current. This current flows through the internal wiring to the output terminals for connection to an inverter. The bifacial design allows the rear side to capture reflected light from the ground or surrounding surfaces. This dual-sided absorption increases total energy production beyond standard single-sided panels. The half-cut technology reduces resistance within each cell, minimizing power loss during transmission. Optimized soldering ensures strong connections that withstand thermal expansion and contraction cycles. The panel maintains linear performance over decades, delivering consistent power output year after year. Its self-cleaning glass surface reduces dust accumulation to maintain high efficiency levels. This system works efficiently even in low-light conditions due to superior cell sensitivity and design.
