What a module pre-shipment inspection should cover
EL imaging, power binning and frame tolerance checks matter more than the headline wattage on the datasheet.
Pre-shipment inspection should include electroluminescence imaging on a sample from each production batch, power measurement at STC, and a frame and junction box check against the drawing.
Ask for the inspection report to reference the batch and pallet numbers, so the findings can be traced to the delivered goods.
