DSBN156 TOPCon Solar Panel 630W
High efficiency dual-glass bifacial N type solar module
DSBN156 High-Efficiency Bifacial N-Type TOPCon Solar Module
The DSBN156 solar panel utilizes advanced 182mm wafers and bifacial N-type TOPCon cell technology, offering superior energy efficiency and rear-side power gain. With excellent durability, smart design, and outstanding long-term performance, it's engineered to maximize energy output and return on investment in utility, commercial, and residential solar projects.
Key Features:
Advanced Bifacial Power Generation
Equipped with bifacial technology, the DSBN156 module delivers 5%–25% additional power from the rear side under different ground and installation conditions, significantly improving overall energy yield.
High-Efficiency Cell Design
Built with multi-busbar (MBB) and high-density interconnect technology, each cell achieves >23.0% efficiency, enhancing module performance and power output.
Dual-Glass Encapsulation for Durability
Featuring dual-glass construction and a corrosion-resistant aluminum frame, the module offers excellent protection against moisture, UV, and environmental stress, ensuring stable power output over time.
Industry-Leading Quality Assurance
Manufactured on a fully automated production line, integrated with MES and ERP systems for precise process control. Each panel undergoes three rounds of electroluminescence (EL) testing and strict visual inspections for superior reliability.
Outstanding Performance & Reliability
0~+5W positive power tolerance, guaranteeing actual output meets or exceeds rated power.
N-type cells eliminate Light-Induced Degradation (LID), ensuring stable, long-term performance.
Proven resistance to Potential-Induced Degradation (PID).
Robust Mechanical Strength
Designed to endure harsh conditions:
Withstands 5400 Pa snow loads
Withstands 2400 Pa wind pressure
Passed rigorous hail impact tests
Certified Fire Safety & Weather Resistance
Complies with international fire safety standards and long-term environmental durability certifications.
