SPIC New Energy GDT120A-635 635W HJT Bifacial Solar Panel
Model GDT120A-635 | HJT | 120 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The SPIC New Energy GDT120A-635 is a high-output solar panel built for commercial and utility-scale applications. It combines HJT and bifacial technology for strong energy generation from both sides of the module. With a rated power of 635 Wp and module efficiency of 22.44%, it is designed for installations that need excellent power density. The monocrystalline construction supports stable performance in demanding environments. Its 1500V system rating and low temperature coefficients help improve long-term energy yield. The module also offers a 15-year product warranty and a 25-year performance warranty, making it a practical choice for reliable solar projects.
Key Benefits
High power output: Delivers 635 Wp, which suits larger systems that need strong output per module.
Excellent efficiency: Reaches 22.44% efficiency, helping maximize energy production in limited roof or ground space.
Bifacial gain potential: Rear-side generation can improve total harvest when the installation surface reflects light.
HJT performance: HJT technology supports strong thermal behavior and consistent operation across changing conditions.
Long service life: The 15-year product warranty and 25-year power warranty support long-term project confidence.
How It Works
The GDT120A-635 converts sunlight into electricity through monocrystalline HJT cells. HJT design combines crystalline silicon with thin amorphous layers for improved charge collection. This helps the panel deliver strong output and stable performance under real-world operating conditions. The bifacial structure captures light from the front and rear surfaces. That design can raise total energy generation when the array is mounted above reflective ground, rooftops, or solar tracking systems. The module is also engineered for durability, so it can continue producing power across wide temperature ranges and high-voltage system designs.
HJT Cell Conversion: Sunlight activates the cell layers, which convert light into usable DC electricity. The heterojunction structure supports efficient charge movement and low energy loss.
Bifacial Energy Capture: The rear side can absorb reflected light and add extra generation. This is especially useful in bright or elevated installations.
System-Level Integration: The 1500V rating supports modern solar arrays and reduces balance-of-system complexity. That makes it suitable for large-scale project designs.
