21、INTERNATIONAL ELECTROTECHNICAL COMMISSION TERRESTRIAL PHOTOVOLTAIC (PV) MODULES DESIGN QUALIFICATION AND TYPE APPROVAL Part 2: Test procedures FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical comm

22、ittees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic elds. To this end and in addition to other activities, IEC publishes International Standards, Technical Specications, Technical Re

23、ports, Publicly Available Specications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and n

24、ongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements o

25、f IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are

26、accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote intern

27、ational uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in th

28、e latter. 5) IEC itself does not provide any attestation of conformity. Independent certication bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certication bodies. 6) All users sho

29、uld ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other dam

30、age of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of

31、 the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent righ

32、ts. International Standard IEC 61215-2 has been prepared by IEC technical committee 82: Solar photovoltaic energy systems. This rst edition of IEC 61215-2 cancels and replaces the second edition of IEC 61215 (2005) and parts of the second edition of 61646 (2008) and constitutes a technical revision.

33、 FEBRUARY 28, 2017 UL 61215-2 5UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL The main technical changes with regard to these previous editions are as follows: This standard includes the testing procedures formally Clause 10 of the previous

34、 edition. Revisions were made to subclauses NMOT (replaces NOCT MQT 05), performance measurements (MQT 06), robustness of terminations (MQT 14) and stabilization (MQT 19). The text of this standard is based on the following documents: FDIS Report on voting 82/1048/FDIS 82/1076/RVD Full information o

35、n the voting for the approval of this standard can be found in the report on voting indicated in the above table. A list of all parts in the IEC 61215 series, published under the general title Terrestrial photovoltaic (PV) modules Design qualication and type approval, can be found on the IEC website

36、. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under http:/webstore.iec.ch in the data related to the specic publicatio

37、n. At this date, the publication will be reconrmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users s

38、hould therefore print this document using a colour printer.

39、with respect to device technology), the sub-parts of Part 1 dene technology variations and Part 2 denes a set of test procedures necessary for design qualication and type approval. The test procedures described in Part 2 are valid for all device technologies. FEBRUARY 28, 2017 UL 61215-2 7UL COPYRIG

40、HTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL TERRESTRIAL PHOTOVOLTAIC (PV) MODULES DESIGN QUALIFICATION AND TYPE APPROVAL Part 2: Test procedures 1 Scope and object This International Standard series lays down IEC requirements for the design qualic

41、ation and type approval of terrestrial photovoltaic modules suitable for long-term operation in general open-air climates, as dened in IEC 60721-2-1. This part of IEC 61215 is intended to apply to all terrestrial at plate module materials such as crystalline silicon module types as well as thin-lm m

42、odules. This standard does not apply to modules used with concentrated sunlight although it may be utilized for low concentrator modules (1 to 3 suns). For low concentration modules, all tests are performed using the current, voltage and power levels expected at the design concentration. The objecti

43、ve of this test sequence is to determine the electrical and thermal characteristics of the module and to show, as far as possible within reasonable constraints of cost and time, that the module is capable of withstanding prolonged exposure in general open-air climates. The actual lifetime expectancy

44、 of modules so qualied will depend on their design, their environment and the conditions under which they are operated. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
