26、AL FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in

27、the electrical and electronic elds. To this end and in addition to other activities, IEC publishes International Standards, Technical Specications, Technical Reports, Publicly Available Specications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to t

28、echnical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and nongovernmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Org

29、anization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 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 technic

30、al committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations 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 Publica

31、tions 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 international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their nation

32、al and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be

33、in conformity with an IEC Publication. 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 Committee

34、s for any 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

35、 Normative 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

36、responsible for identifying any or all such patent rights. International Standard IEC 62108 has been prepared by IEC technical committee 82: Solar photovoltaic energy systems. The text of this standard is based on the following documents: FDIS Report on voting 82/494/FDIS 82/504/RVD JANUARY 25, 2012

40、CATION AND TYPE APPROVAL 1 Scope and object This International Standard species the minimum requirements for the design qualication and type approval of concentrator photovoltaic (CPV) modules and assemblies suitable for long-term operation in general open-air climates as dened in IEC 60721-2-1. The

41、 test sequence is partially based on that specied in IEC 61215 for the design qualication and type approval of at-plate terrestrial crystalline silicon PV modules. However, some changes have been made to account for the special features of CPV receivers and modules, particularly with regard to the s

42、eparation of on-site and in-lab tests, effects of tracking alignment, high current density, and rapid temperature changes, which have resulted in the formulation of some new test procedures or new requirements. The object of this test standard is to determine the electrical, mechanical, and thermal

43、characteristics of the CPV modules and assemblies and to show, as far as possible within reasonable constraints of cost and time, that the CPV modules and assemblies are capable of withstanding prolonged exposure in climates described in the scope. The actual life of CPV modules and assemblies so qu

44、alied will depend on their design, production, environment, and the conditions under which they are operated. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references
