The LumiSolarMobile system is a multi-purpose electroluminescence inspection system for solar cells and solar modules. Micro-cracks, cell failures, inhomogeneities and other defects which are extremely difficult to detect visually can be detected clearly. The LumiSolarMobile system is a lightweight and portable device and allows quick mounting and easy transport.

  • Electroluminescence inspection system for solar cells & modules

Data Sheets


LumiSolarMobile Software The LumiSolarMobile software controls the camera and visualizes the data sets. The program can generate intensity profiles from the 16bit high dynamic range image data. Basic picture manipulation procedures are included in the software. Dimension measurements of artefacts are possible following calibration as well as remote control of power supply.
