33、EN 62108:2016IEC 62108:2016 IEC 2016 5 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ CONCENTRATOR PHOTOVOLTAIC (CPV) MODULES AND ASSEMBLIES DESIGN QUALIFICATION AND TYPE APPROVAL FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
34、all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards,
35、Technical Specifications, Technical Reports, Publicly Available Specifications (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
36、 work. International, governmental and non-governmental 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
37、. 2) The formal decisions or agreements of 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 recom
38、mendations for international use and are 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 an
39、y end user. 4) In order to promote international 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 pub
40、lication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification 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 indep
41、endent certification bodies. 6) All users should 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
42、personal injury, property damage or other damage 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
43、 references cited in this publication. Use of 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 responsibl
44、e for identifying any or all such patent rights. International Standard IEC 62108 has been prepared by IEC technical committee 82: Solar photovoltaic energy systems. This second edition cancels and replaces the first edition, issued in 2007. It constitutes a technical revision. The main technical ch
45、anges with regard to the previous edition are as follows: a) Changes in outdoor exposure from 1000 h to 500 h. b) Changes in current cycling during thermal cycling test. c) Added dust ingress test. d) Eliminated thermal cycling associated with damp heat test. e) Eliminated UV exposure test.

This publication has be
47、en 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 website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the p
48、ublication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

49、nts for the design qualification and type approval of concentrator photovoltaic (CPV) modules and assemblies suitable for long-term operation in general open-air climates as defined in IEC 60721-2-1. The test sequence is partially based on that specified in IEC 61215-1 for the design qualification and type approval of flat-plate terrestrial crystalline silicon PV modules. However, some changes have been made to account for the special features of CPV receivers and modules,
