• High module conversion efficiency:
    Module efficiency up to 21.3 % achieved through advanced cell
    technology and manufacturing process.
  • Suntech’s current sorting process:
    Up to 2 % power loss caused by the current mismatch could be
    diminished by the current sorting technique to maximize system
    power output
  • Excellent weak light performance:
    More power output in weak light conditions, such as cloudy,
    morning and sunset.
  • Lower operating temperature:
    Lower operating temperature and temperature coefficient
    increases the power output.
  • Extended wind and snow load tests:
    Module certified to withstand extreme wind (2400 Pascal) and
    snow loads (5400 Pascal).
  • Withstanding harsh environment:
    Reliable quality leads to better sustainability even in harsh
    an environment like desert, farm, and coastline.
