STC & NMOT Measurement

Purpose:

It’s to determine how the electrical performance of the module varies with load at STC (1000W/m2, 25℃ cell temperature, with the IEC60904-3 reference solar spectral irradiance distribution) and at NMOT (an irradiance of 800W/m2 and an ambient temperature of 20℃ with the IEC 60904-3 reference solar spectral irradiance distribution) the measurement at STC is used to verify the name plate information of the module.

Standard:

According to IEC61215 standard requirement
