Bright Solar TD-620TRG-144HC 620W N-Type TOPCon Bifacial Solar Panel
TD-620TRG-144HC | N-Type TOPCon | 144 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Bright Solar TD-620TRG-144HC 620W N-Type TOPCon Bifacial Solar Panel delivers exceptional power for utility and commercial projects. This advanced module features 144 high-efficiency N-type cells using TOPCon technology. Its bifacial design captures sunlight from both front and rear sides, boosting total energy yield significantly. The panel achieves 22.2% efficiency with a positive power tolerance of 0 to +3%. It operates reliably in temperatures ranging from -40°C to +85°C. Built with durable anodized aluminum frames and 2mm glass, it withstands harsh weather conditions. The 620W output supports high-voltage systems up to 1500V DC. This solar panel is ideal for reducing energy costs and maximizing ROI in solar installations. Manufactured by Bright Solar Technology Co., Ltd. in China, it ensures competitive quality. The 15-year product warranty and 30-year linear power warranty guarantee long-term performance.
Key Benefits
High Power Output: Generates 620W of power with a tolerance range of 0 to +3% for reliable performance.
Bifacial Energy Gain: Captures light from both sides to achieve up to 80% bifacial factor and increased total output.
Advanced TOPCon Technology: Utilizes N-type TOPCon cells to minimize degradation and improve efficiency in low-light conditions.
Superior Durability: Features a robust frame and 2mm glass to withstand 5400Pa wind and 2400Pa snow loads.
Long-Term Warranty: Includes a 15-year product warranty and a 30-year linear power warranty for decades of reliability.
How It Works
This solar panel converts sunlight into electricity using advanced N-type TOPCon technology. The bifacial design allows it to harvest energy from reflected light on the rear side. High-density multi-busbar cells reduce internal resistance and improve current collection efficiency. The module operates efficiently across a wide temperature range from -40°C to +85°C. Its robust construction ensures stable performance even under extreme wind or snow loads. The IP68 junction box protects internal components from moisture and dust ingress. This technology minimizes power loss caused by shading or low-light environments effectively. The result is a high-efficiency system that maximizes energy generation per square meter.
Bifacial Light Capture: The transparent backsheet captures sunlight from the rear, adding up to 80% extra power to the front-side output. This dual-sided generation significantly boosts total energy yield in open or reflective installations.
TOPCon Cell Efficiency: N-type TOPCon cells use a tunnel oxide passivation layer to reduce electron recombination and increase voltage. This design inherently lowers Light Induced Degradation, ensuring consistent power output over decades.
High-Density Busbar Design: Multiple busbars on each cell reduce electrical resistance and improve current flow to the junction box. This encapsulation technology minimizes power loss and enhances performance under shaded or low-light conditions.
