Electroluminescence (EL) Testing as a Quality Assurance Tool

pv magazine Roundtables USA on Electroluminescence (EL) Imaging as a QA Tool

pv magazine Roundtables USA’s Session 1, “Optimizing Solar Systems & Hardware”, included a presentation by CEA’s Senior Project Manager/Solar Engineer, Claire Kearns-McCoy, on the importance of using EL imaging to ensure the quality of your PV modules.

Claire explains how EL image testing detects issues that are frequently found at various points in the PV module lifecycle, from the factory to the field. She highlights that EL testing is a critical piece in preventing module underperformance over the lifetime of a solar project.
