This inspection covers visual inspection, quantity verification, field testing and measurements, and certification checks such as IEC, UL, and CE marking. These inspections can be performed at various stages, including: Apart from our quality control inspections for solar PV, we provide a variety of vendor assessment services.
Inspections are continually made to ensure defects are not found. This is a highly efficient way to stop defective goods from being sent to clients. HQTS has over 25 years of experience in industry-leading quality control for various industries, including solar panel testing.
CEA’s comprehensive pre-shipment inspections identify defects exceeding the AQL standards and ensure defective products are not shipped. Identifying and removing defective products reduces risk and optimizes the performance and life of your products.
A solar PV module sample will be considered to be rejected due to its observable quality defects if any one of the following conditions are met: If any single observed defect has been evaluated as a Severity of 5. A Severity of 5 indicates a major quality issue; a critical failure or a fraudulent module.
Inspectors should be sufficiently familiar with defects unique to used modules such they can be identified during the inspection of ostensibly new products. Once the inspection checklist is complete the inspector can review the results to determine whether the inspected module is acceptable for the intended application.
Inadequate loading practices by the factory can result in damaged finished PV modules either during loading of the containers or at some point during transportation. Further, finished products that were previously rejected by CEA or that were not inspected by a third party altogether may end up getting shipped without oversight.
