Why EL Testing of Solar Module is Important?
Nov 08 , 2021

1. What is Electroluminescence(El) testing?When current passes through solar PV cells, light emission occurs. This phenomenon is called Electroluminescence(EL). Testing of modules using this phenomenon can detect hidden defects in the structure of PV cells. This method makes the current distribution visible in the solar PV module and helps detect defects. With the help of an EL test, a PV m...
