Suntech 320 Watt Mono Solar Module

SKU: STP320S-20/Wfh


  • High power output: Compared to normal module, the power output can increase 5W-10W
  • Excellent weak light performance: More power output in weak light condition, such as haze, cloudy and morning
  • Extended load tests: Module certified to withstand front side maximum static test load (5400 Pascal) and rear side maximum static test loads (3800 Pascal)
  • High PID resistant: Advanced cell technology and qualified materials lead to high resistance to PID
  • Lower hot spots: Reduce the hot spots and minimize panel degradation
  • Withstanding harsh environment: Reliable quality leads to a better sustainability even in harsh environment like desert, farm and coastline
