IEC 62941 pdf download.Terrestrial photovoltaic (PV) modules – Guidelines for increased confidence in PV module design qualification and type approval
1 Scope
This Technical Specification is applicable to sites manufacturing photovoltaic (PV) modules certified to IEC 61 21 5 or IEC 61 646 for design qualification and type approval. The design qualification and type approval of PV modules depend on appropriate methods for product and process design, as well as appropriate control of materials and processes used to manufacture the product. This technical specification lays out best practices for product design, manufacturing processes, and selection and control of materials used in the manufacture of PV modules that have met the requirements of IEC 61 21 5, IEC 61 646, or IEC 621 08. These guidelines also form the basis for factory audit criteria of such sites by various certifying and auditory bodies. The object of this technical specification is to provide more confidence in the ongoing consistency of performance and reliability of certified PV modules. The requirements of this technical specification are defined with the assumption that the quality management system of the organization has already fulfilled the requirements of ISO 9001 or equivalent quality management system. By maintaining a manufacturing system in accordance with this guideline, PV modules are expected to maintain their performance as determined from the test sequences in IEC 61 21 5, IEC 61 646, or IEC 621 08. This technical specification is applicable to all PV modules independent of design and technology i.e. flat panel, concentrator photovoltaic (CPV). Quality controls for CPV and nonconventional flat-plate manufacturing will differ somewhat from those of more conventional designs; this technical specification has not considered these differences.
3 Terms, definitions and acronyms
For the purposes of this document, the terms and definitions in ISO 9000:2005, IEC TS 61 836 and the following apply. 3.1 containment action taken to protect the customer from the effect of a situation. Containment may include correcting an existing situation or adding additional screening or retesting 3.2 control plan documented description of the systems and processes required for controlling the product and process quality by addressing the key characteristics and engineering requirements 3.3 customer end user, investor, installer who purchases modules from the organization 3.4 design lifetime design target period during which PV modules are expected to safely satisfy the specified performance under the specified conditions Note 1 to entry: Specified conditions include application of use, installation environment configurations and operation conditions of the PV module in use. The design target period is set considering changes in performance of PV modules due to aging degradation of parts and materials used in the stated environment. 3.5 Design Failure Mode and Effects Analysis DFMEA application of the Failure Mode and Effects Analysis (FMEA) method specifically to product/service 3.6 define, measure, analyse, improve and control DMAIC data-driven quality strategy for improving processes and an integral part of a Six Sigma quality initiative 3.7 electrostatic discharge ESD sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown Note 1 to entry: Electrostatic discharge events are known to damage semiconductor devices such as diodes. 3.8 Failure, Modes and Effects Analysis FMEA document that defines the design, process, or solution with requirements and includes potential modes, causes and severity of effects of failure, along with an evaluation of the likelihood of their occurrence and ease of detection Note 1 to entry: FMEA provides a mechanism to prioritize the risks and take appropriate mitigation steps.3.9 key materials materials that affect safety, reliability, or product performance of the PV module Note 1 to entry: Key materials may include indirect materials. Those materials which are used during the manufacturing process of PV modules, but are not found in the end product. In most chemical processes, catalyzers are indirect materials. 3.1 0 organization entity that supplies modules to the customer and that has responsibility for design, production, and after-service for the modules Note 1 to entry: The organization may subcontract some of its responsibilities for design, production, and the after-sales service. 3.1 1 out of box audit pre-shipment audit is meant to simulate what a customer would experience when they open the packing box
