Cell Type
N-Type TOPCon

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.
