• High-speed analysis: avoid delays and easily keep up with the factory’s production speed
  
  
• Trained with 10+ years of defect data
  
  
• Accepted by all leading Tier 1 manufacturers
  
  
• 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
