Solar Module EL Infrared Testing
 
Electrostrictive the detection method of the light emitting ( Electrolum inescence, EL), using an electrolum inescent light-emitting principle for crystalline silicon solar cells and components of the near infrared imaging test is promptly detected by the EL test chart solar cells and components may exist defects, is an effective detection of the cell, the method of assembly, the EL test plays an increasingly important role in solar module quality and control. 



Solar Module Flash Testing 
 
The purpose of the test is to calibrate the output power of the module, and test its output characteristics to determine the quality and grade of the product. The measuring is carried out strictly according to STC (Standard test conditions).



Lamination 
 
In lamination step, the following materials are laminated together
through the vacuum.



Back film-Eva-Solar cell-Eva-Glass, are stuck together by the glue
through 145 degrees high temperature for 16 minutes. 



In this step, long-chain polymers are cross-linked to productions 
is checked chemically by us when it reaches the laboratory, to see 
whether the achieved degree of cross-linking is at least 80%.



Namkoo controls the parameters of the lamination process for 
each lamination run according to the manufacture' s date for eva 
(abbreviation for ethylene vinyl acetate; a transparent plastic layer), 
since the parameters differ from manufacturer to manufacturer. 
What is decisive for us is a test, which checks the cross-linking of 
eva. Eva protects the solar cells against corrosive influences from 
outside. The solar cell is so to speak "encapsulated" and thus
protected against water ingress.



Solar Module Framed and Cleaning 
 
By the step the aluminum frame is installed to the laminated module to increase 
the intensity of the module components and its further sealing of the cell in order 
to extend the module lifespan silicon gel is filled between the frame and lass. No 
gap for air coming into the module.
