IEC 61215-2:2016 Solar panel Humidity Freeze machine/low temperature environment chamber/Solar panel testing machine

 

Testing Standard

It's conform IEC61215-2:2016 testing standard 

 

 

Purpose

To determine the ability of the module to withstand the effects of long -term penetration of humidity, & the ability of the module to withstand thermal mismatch , fatigue and others stresses caused by repeated changes of temperature

 

 

Testing Chamber advantage:

Have three function:

1. Damp heat testing ( double 85℃ testing)

2. Thermal cycling testing

Humidity freeze testing
