Photovoltaic products are primarily used in long-term outdoor installations, where product quality directly impacts service life and power generation efficiency. Conducting third-party inspections prior to shipment allows for the early identification and exclusion of defective modules, thereby preventing the high costs associated with returns or replacements once substandard products reach overseas sites. Furthermore, these inspections ensure compliance with the market access standards of various countries-avoiding customs clearance delays or project stoppages-and effectively safeguard the investment returns of both overseas and domestic buyers.

1. Document Verification: Cross-reference orders, product specifications, nameplate data, and certification documents to ensure technical parameters-such as model, power output, and dimensions-meet customer requirements;
2. Visual Inspection: Inspect the PV panel surface for defects such as scratches, micro-cracks, bubbles, color inconsistencies, frame deformation, or detached sealant;
3. Dimensional and Assembly Check: Measure the module's length, width, and thickness; inspect the frame joints and the security of the junction box installation;
4. Electrical Performance Spot-Check: Verify key parameters such as open-circuit voltage and short-circuit current; check for performance degradation or wiring faults;
5. Accessory and Material Verification: Confirm specifications for mounting brackets, cables, and connectors; check that anti-corrosion and insulation materials meet standards;
6. Labeling and Packaging Inspection: Ensure product nameplates and warning labels are intact; verify that packaging meets requirements for moisture and shock protection during ocean transport;
