Product Features:

-----High power output

Compared to 158.75mm module, the power output can increase 25W-30W

-----High PID resistant

Advanced cell technology and qualified materials lead to high resistance to PID

-----Excellent weak light performance

More power output in weak light condition, such as haze, cloudy, and morning

-----Lower operating temperature

Lower operating temperature and temperature coefficient increases the power output

-----Extended load tests

Module certified to withstand front side maximum static test load (5400 Pascal) and rear side maximum static test loads (3800 Pascal)

-----Withstanding harsh environment

Reliable quality leads to a better sustainability even in harsh environment like desert, farm and coastline
