DSBN144 TOPCon Solar Panel 580W
High efficiency dual-glass bifacial N type solar module
DSBN144 High-Efficiency Bifacial TOPCon Solar Module
Powered by advanced 182mm wafers and N-type bifacial TOPCon cell technology, the DSBN144 solar module delivers exceptional energy efficiency and increased energy yield through bifacial power generation-providing up to 5%–25% additional output from the rear side under various conditions.
Key Features & Benefits:
High Conversion Efficiency
Achieves cell efficiency of over 23.0% through optimized multi-busbar (MBB) design and high-density interconnect technology, maximizing energy output and system performance.
Enhanced Bifacial Output
Bifacial design captures reflected light from the backside, increasing total power generation in diverse installation environments.
Durable Dual-Glass Structure
Encapsulated with dual-glass and framed with corrosion-resistant aluminum, offering superior durability, improved weather resistance, and long-term energy yield stability.
Precision Manufacturing & Quality Assurance
Manufactured on a fully automated production line with integrated MES and ERP systems for digital logistics and process control. Each module undergoes 100% triple EL testing and visual inspections for optimal quality.
Excellent Mechanical Load Resistance
Designed to withstand extreme weather conditions with resistance to 5400 Pa snow load and 2400 Pa wind load. Passed rigorous hail impact testing for added reliability.
Superior Performance with No LID
N-type cells naturally eliminate light-induced degradation (LID), ensuring long-lasting high performance and lower degradation rates.
Positive Power Tolerance
Guaranteed 0~+5W positive power tolerance ensures actual output is always equal to or greater than the rated power.
Certified Safety and Reliability
Excellent anti-PID (Potential Induced Degradation) performance and certified fire resistance for enhanced safety and peace of mind.
