Position Summary

The Quality Control Operator is responsible forinspecting and electrically testing solar modules at critical stages of production to ensure compliance with internal, regulatory, and customer specifications. This role includesoperation of electroluminescence (EL), sun simulator (flash tester),HiPotand Final Inspectionteststations, defect classification, calibration verification, and final visual inspection toidentifyand document nonconformities prior to product release.

Key Responsibilities

EL Image Review & Defect Categorization

• Capture and analyze EL images atin processand final inspection stages
• Identifyand classify celllevel andmoduleleveldefects (cracks, inactive areas, black spots, finger interruptions, shunts, etc.)
• Categorize defects per internal grading criteria andcustomerspecificrequirements
• Flag modules for rework, downgrade, or rejection based on defect severity
• Maintainaccurateinspection and defect records in the MES or quality tracking system

Sun Simulator (Flash Test) Operation & Calibration

• Operate sun simulator equipment to measure module electrical performance
• Verify test results against product specifications and binning requirements
• Identifyabnormal electrical trends or outofspec conditions and escalate per quality procedures
• Perform routine verification checks and supportcalibration activitiesof the sun simulator, including reference cell checks and system stability monitoring
• Ensure calibration status, reference devices, and test configurationscomply withinternal procedures and applicable IEC/UL requirements
• Document test results, calibration checks, and equipment status accurately

HiPotTesting

• OperateHiPottest stations to verify module electrical insulation and safety compliance
• Ensure correct test parameters are applied per product type and applicable standards
• Identifyand segregate failed units and initiate nonconformance documentation
• Follow all safety procedures associated withhighvoltagetesting equipment

Final Visual Inspection

• Perform 100% visual inspection of finished modules against cosmetic and workmanship standards
• Inspect for frame damage, glass defects, back sheetanomalies, junction box alignment, label placement, and sealant quality
• Verify correct labeling, barcoding, and traceability markings
• Segregate nonconforming units andinitiateappropriate documentation

Documentation & Communication

• Complete inspection checklists, electrical test records, defect logs, and shift reports accurately and on time
• Communicate recurring defects, electrical performance trends, or equipment issues to production, engineering, and quality teams
• Participate in root cause analysis and corrective action activities
• Support internal and external audits by providing inspection, test, and calibration records

Qualifications
