156 N-Type TOPCon Half Cut Cells
The 156 Half-Cut TOPCon series pushes wattage up to 650 Wp — optimised for ground-mount utility plants with best-in-class efficiency and durability.
Technical Excellence
Multi-Busbar Technology
Better light trapping and current collection improve module power output and reliability. Reduces internal resistance and micro-crack impacts significantly compared to standard cell designs.
Thermal Mastery
Optimized temperature coefficient ensures maximum energy yield even in extreme heat environments common in large-scale solar farms.
Mechanical Strength
Certified to withstand severe environmental conditions: wind load (2400 Pascal) and snow load (5400 Pascal).
Anti-PID Guarantee
Limited power degradation caused by PID (Potential Induced Degradation) effect is guaranteed via optimized mass-production processes and material control.
