Solar Modules MICRO/Mini invisible Cracks Test Using Electroluminescence Method (EL test)

Electroluminescence (EL) is the recommended method to find Micro or mini cracks in solar modules.This test is Required for where as damage during Transporation or Natural Disaster .This EL test will help Module Efficency for Future.Incase any micro cracks in modules ,efficiency will lose more chance by a year.This EL Test  is an Optical and Electrical Phenomenon in which a material emits light in response to the passage of an electric current or to a strong electric field. This is distinct from black body emission resulting from heat (incandescence), from a chemical reaction (chemiluminescence), sound (sonoluminescence), or other mechanical action (mechanoluminescence).
