Most acceptance checks for newly purchased EL equipment verify only one thing: the device powers on. This article lays out a practical acceptance workflow for PV plant owners and EPC teams receiving an EL inspection system — from checking the packing list against the contract, through a structured first-light test on real modules, to verifying that image files, software licenses, and training deliverables actually match what was ordered. It explains why a quick indoor power-on test misses the failure modes that matter in the field, which items should be tested before signing the acceptance form, what evidence to archive in case a warranty dispute arises later, and which checks are reasonable to skip for small orders. A dedicated FAQ covers acceptance timing, who should be present, and how to handle discrepancies found after signing.
