IEC 62941:2019

Overview

IEC 62941:2019 is an international standard published by the International Electrotechnical Commission (IEC) that defines a quality system for manufacturing terrestrial photovoltaic (PV) modules. This standard applies specifically to organizations producing PV modules certified under the IEC 61215 series and IEC 62108 (design qualification and type approval), as well as IEC 61730 (safety qualification and type approval). IEC 62941:2019 provides a structured framework and best practices for product design, manufacturing processes, and material control to ensure consistent performance and reliability of certified PV modules throughout their lifecycle.

This standard assumes that manufacturers already implement a quality management system based on ISO 9001 or an equivalent system, and it is designed to complement, not replace, such quality frameworks. By implementing IEC 62941:2019, manufacturers can maintain PV module performance in line with rigorous testing and certification requirements, ensuring long-term product reliability and safety.

Key Topics

• Quality System Framework for PV Modules IEC 62941 establishes a comprehensive quality system tailored explicitly for PV module manufacturing, addressing processes essential for compliance with relevant IEC certification standards.

• Manufacturing Process Control Emphasizes control over process design, production operations, and monitoring resources such as performance rating (IV) measurement equipment and solar simulators. It highlights the importance of validated and documented production controls to guarantee module consistency.

• Material Selection and Control Focuses on the systematic selection, inspection, procurement, and use of materials critical for PV module durability and performance.

• Design and Development Management Covers planning, input requirements, design outputs, and change controls related to both product and manufacturing processes to optimize module quality.

• Audit and Monitoring Procedures Incorporates factory audit criteria used by certification bodies, continuous monitoring, performance data analysis, and corrective actions to ensure ongoing product compliance and improvement.

• Compliance and Certification Support Linked closely with certification standards IEC 61215, IEC 62108, and IEC 61730, helping manufacturers sustain their qualified status through consistent quality management.

Applications

• PV Module Manufacturers This standard is crucial for manufacturers aiming to produce terrestrial PV modules that meet international safety, performance, and reliability standards, whether flat-panel or concentrator photovoltaic (CPV) designs.

• Quality Assurance Teams Enables QA professionals to implement and maintain effective quality control strategies aligned with international certification and testing standards.

• Certification and Auditing Bodies Provides criteria for factory inspections and audits, facilitating independent verification of manufacturing quality systems tailored to PV module production.

• Renewable Energy Project Developers Developers and suppliers of solar energy solutions can specify modules manufactured under IEC 62941 to ensure product longevity and minimize risk.
