  • Identification and classification of up to 15 cell-inherent defect types

  • Improve silicon solar cell efficiency of your production and shipment

  • Replace defective solar modules at the factory prior to shipment

Who can benefit from EL image testing?

  • Developers PV projects
  • EPCs
  • Financiers
  • Insurers

What is Electroluminescence testing in solar?

Electroluminescence testing in solar is a technique that uses the light emission phenomenon of photovoltaic (PV) cells to detect defects and failures in solar modules. When a current is applied to a PV cell, it emits light in the infrared spectrum, which can be captured by a camera and analyzed to reveal the quality and performance of the cell.

What defects can be found in EL testing?

  • Micro-cracks
  • Broken cells
  • Bus bar contact defects
  • Missing or interrupted screen-printed fingers
