ELECTROLUMINESCENCE TEST UNIT

Electroluminescence inspection is a method that informs us about cyristal structure of cells that constitute PV modules with analysing of infrared wawelength light emitted by modules with back fedding of electric current.

Using this method; micro cracks on the module, problems (cell soldering defects, ohmic contacts, etc.) that occur during cell and module production, malfunctions in module assembly and non-working areas can be easily identified.

If the photovoltaic modules are not transported and assembled properly, then structural defects occur in the cells. Detecting these defects in the laboratory environment is very laborious and costly, so it is more appropriate to detect them at the plant site.

Proerk Engineering provides electroluminescence testing services both in the factory environment and at the plant site with the electroluminescence units developed as a result of R & D studies.
