SPIC New Energy GDT120A-640 640W Bifacial HJT Monocrystalline Solar Panel
Model No. GDT120A-640 | Bifacial HJT | 120 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The SPIC New Energy GDT120A-640 is a high-performance 640W bifacial HJT solar panel built for modern commercial and utility-scale systems. It combines monocrystalline cell technology with heterojunction architecture for strong energy yield and stable long-term output. The module offers a high efficiency rating of 22.1%, helping maximize production on limited roof or ground space. Its bifacial design can capture additional light from the rear side. This supports stronger real-world generation in reflective environments. The durable structure, 1500V system rating, and IP68 junction box make it suitable for demanding solar installations.
Key Benefits
High Power Output: Delivers 640W of maximum power for strong energy production in large-scale projects.
Bifacial Gain Potential: Captures light from both sides to improve generation in suitable installation environments.
High Efficiency Design: Reaches 22.1% efficiency, which supports better space utilization and system output.
Long-Term Reliability: Includes a 15-year product warranty and a 25-year power warranty for added confidence.
Durable Construction: Uses an anodized aluminium frame, IP68 protection, and robust 35.3 kg construction.
How It Works
This solar panel converts sunlight into usable electricity through advanced monocrystalline HJT cells. The half-cell layout helps reduce resistive losses and improve performance under varied conditions. Bifacial operation allows the rear side to contribute extra energy when reflected light is available. That makes the module especially useful on light-colored roofs, open fields, and elevated mounting structures. The panel is engineered for stable electrical performance, safe system integration, and long operating life. Its low degradation rate helps preserve output across many years of service.
HJT Cell Conversion: The heterojunction cells absorb solar radiation and convert it into electrical current efficiently. This structure supports high open-circuit voltage and dependable energy yield.
Bifacial Energy Capture: The panel can generate power from both front and rear surfaces. Rear-side output increases when the installation environment reflects more light.
System Integration: The 1500V maximum system voltage supports modern string design. MC4 connectors and 4 mm² cable help simplify installation and connection.
