Ecolab EL HR


Ecoprogetti’s High Resolution Electroluminescence Test Station is our best EL tester. The ECOLAB EL HR with a 6 camera system, indentifies small faults on the cells of the PV Panel, such as micro-cracks and finger interruptions that can’t be detected by the naked eye.

The ECOLAB EL is a high-resolution electroluminescence inspection system that can be placed before lamination and at the end of the production line. This machine enables the user to perform a deep and extensive check of the quality of the PV panels and allows to keep the process monitored and to improve it based on the raw materials in use. With the assistance of adapters, it’s possible to test single cells or strings not yet laminated. Additionally, high sensitive cameras and the neural network software enable the machine to automatically detect defects of the PV panel.
