The Pre-Shipment Inspection (PSI) is one of many types of quality control inspections conducted by LONGSUN SOLARELECTRIC CO.,LTD. With no exception, monocrystalline solar panel is also inspected for quality control prior to shipment. This inspection is based on the product's Standard Acceptable Quality Limit specification or on customer request. Based on these criteria and procedures, samples are randomly selected and defects are checked. The Pre-Shipment Inspection helps both ourselves and customers to reduce the potential risk of delivery delay or/and fix or redo products. At last, the product will be photographed to ensure that the order is in perfect condition, complete, and properly packaged for shipment.
