WINAICO WST-630NHX66-A4 625–630W N-Type HJT Bifacial Solar Panel
Model WST-630NHX66-A4 | N-Type HJT | 132 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The WINAICO WST-630NHX66-A4 is a high-performance bifacial solar panel built with N-type HJT monocrystalline cells. It is designed for utility-scale projects that need strong energy yield and dependable long-term performance. The module delivers up to 630 Wp with module efficiency reaching 23.3%. Its glass-glass structure and advanced bifacial design help capture light from both sides. That makes it a strong choice for installations with reflective ground conditions. The panel also carries a 15-year product warranty and a 25-year power warranty. Performance retention is supported by low degradation over time.
Key Benefits
High Power Output: The module reaches 630 Wp, supporting strong generation capacity in large solar arrays.
Excellent Efficiency: Up to 23.3% efficiency helps maximize output from available roof or ground space.
Bifacial Energy Gain: Bifacial construction allows the rear side to contribute additional generation under suitable conditions.
Long-Term Reliability: The 15-year product warranty and 25-year power warranty provide added confidence for project owners.
Low Degradation: A total degradation rate of 0.32% supports stable performance across the operating life.
How It Works
This solar panel converts sunlight into electricity using advanced N-type HJT monocrystalline cells. Its bifacial design helps generate power from both the front and rear sides of the module. The front glass captures direct sunlight, while the rear glass can contribute extra output from reflected light. That makes the panel especially effective in utility-scale layouts with light-colored ground, elevated mounting, or open field installations. The glass-glass build also supports durability and environmental protection. Together, these features help maintain reliable output over many years of service.
N-Type HJT Cell Conversion: The panel uses heterojunction technology to convert sunlight efficiently. This structure supports high efficiency and strong temperature behavior.
Bifacial Energy Collection: Both sides of the module can contribute to generation. Rear-side output depends on the installation surface and light reflection.
Glass-Glass Protection: Semi-tempered glass on both sides improves structural strength. It also helps protect the cells from weather-related stress.
