module defects

More than 70% of global solar manufacturing facilities exhibited “major” or “critical” defects in 2025, according to a new report from Intertek CEA.

New solar manufacturing facilities show higher rates of product defects, PV Tech has heard from Joerg Althaus of Clean Energy Associates.

PV Tech spoke with Joerg Althaus of CEA about the under-explored issues with solar racking, trackers and other technical concerns.

Cold soldering has become the highest frequency problem found during pre-shipment electroluminescence inspection of PV modules, write CEA's Paul Wormser and Jake Edie.
