SPIC New Energy GDT120A-650 650W Bifacial HJT Solar Panel
Model GDT120A-650 | Bifacial HJT | 120 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The SPIC New Energy GDT120A-650 is a high-output bifacial HJT solar panel built for demanding commercial and utility projects. This 650W module combines heterojunction cell technology with a 120-cell layout, helping deliver strong efficiency and reliable energy generation. Its monocrystalline construction supports consistent performance, while the bifacial design helps capture additional light from the rear side. The panel is engineered for long service life, with a 15-year product warranty and a 25-year power warranty. It is a practical choice for installations that need high power density, stable output, and durable field performance.
Key Benefits
High Power Output: The module delivers up to 650Wp for stronger system yield. This supports fewer panels for the same design target.
Excellent Efficiency: Efficiency reaches 22.97%, which improves energy production in limited roof or land areas. That makes it suitable for space-conscious projects.
Bifacial Gain Potential: The bifacial architecture can capture reflected light from behind the module. This can improve total system output in favorable installations.
HJT Cell Technology: Heterojunction cells are known for strong temperature behavior and efficient light capture. This supports dependable energy generation across varied conditions.
Long-Term Value: The 15-year product warranty and 25-year power warranty add confidence for long operating lifetimes. Degradation is stated at 0.32% per year.
How It Works
The GDT120A-650 converts sunlight into electricity through monocrystalline HJT cells arranged in a 120-cell format. HJT technology combines different silicon layers to improve charge collection and support high efficiency. The bifacial design can generate power from both the front and rear surfaces. This helps increase overall output when the installation reflects light from the ground or mounting structure. The module is designed for stable operation across a wide temperature range. Its electrical characteristics and 1500V system rating support modern large-scale solar system design.
HJT Cell Conversion: The heterojunction cell structure helps turn incoming sunlight into usable direct current. It is designed for strong efficiency and lower performance loss under heat.
Bifacial Light Capture: The rear side of the module can absorb reflected sunlight. This can add energy yield in elevated or high-albedo installations.
System Integration: The module operates with standard string inverter systems. Its voltage and current values support efficient array planning and safe installation.
