SolarString EL-inline

The SolarString EL-inline is an electroluminescence testing system for testing of strings before layup. The integration of the system direct after the stringing process gives a direct process Feedback. The rapid image acquisition, the convincing operating concept, and an attractive price turn the SolarString EL-inline into a testing system which is particularly well suited to production.

Electroluminescence test

The layup system places the string to be tested above the inline string tester. The string is automatically contacted and connected to the power supply.

Several cooled CMOS cameras capture high-resolution EL images of each individual cell in a string so that even the smallest microcracks are visible.

Layup System

In the second step, the transmitted light illumination is switched on and thus the position of the string is determined and transferred to the layup control. A user-friendly software interface displays the captured images in the form of a line.

The operator can navigate interactively through the line and view individual images enlarged. The string is automatically evaluated by the software.
