Pre-Shipment Inspection (PSI)

Kiwa PI Berlin will perform a Pre-Shipment Inspection (PSI) of PV modules on a sampling basis prior to shipment approval. Defect rates exceeding the agreed acceptance criteria may result in additional inspections or product rejection as part of the agreed quality control process. Inspections typically include flash testing (I-V measurements), verification of power and insulation resistance related defects, electroluminescence (EL) imaging to identify cell defects, and visual inspection (VI).
