26、EC 2016 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ PHOTOVOLTAIC (PV) MODULE PERFORMANCE TESTING AND ENERGY RATING Part 2: Spectral responsivity, incidence angle and module operating temperature measurements FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organizatio

27、n 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 the electrical and electronic fields. To this end and in addition to other activities, IEC pu

28、blishes International Standards, 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 ma

29、y participate in this preparatory 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 agree

30、ment 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 technical committee has representation from all interested IEC National Committees. 3) IEC P

31、ublications 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 Publications is accurate, IEC cannot be held responsible for the way in which they are used

32、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 national and regional publications. Any divergence between any IEC Publication and the corr

33、esponding national or regional publication 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

34、 any services carried out by independent 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 an

35、d IEC National Committees 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) A

36、ttention is drawn to the 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

37、 IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61853-2 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 82/1133/FDIS

38、82/1156/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 IEC 61853-2:2016 IEC 2016 A list of all parts in the IEC 61853 series

39、 published under the general title Photovoltaic (PV) module performance testing and energy rating, can be found on the IEC website. 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.c

40、h“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IEC 61853-2:2016 IEC 2016 5 INTRODUCTION Photovoltaic (PV) modules are typically rated at standard test conditions (STC) of 25 C cell temperatu

41、re, 1 000 W m 2irradiance, and air mass (AM) 1.5 global (G) spectrum. However, the PV modules in the field operate over a range of temperatures, irradiance, and spectra. To accurately predict the energy production of the modules under various field conditions, it is necessary to characterize the mod

42、ules at a wide range of temperatures, irradiances, angles of incidence, and spectra. Recognizing this issue, IEC Technical Committee 82 Working Group 2 (TC 82/WG 2) has developed an appropriate power and energy rating standard (IEC 61853). The first part of this four-part standard requires the gener

43、ation of a 23-element maximum power (P max ) matrix at four different temperatures and seven different irradiance levels. The P maxmatrix can be generated using an indoor solar simulator method or outdoor natural sunlight method. The outdoor test method introduces little/no spectral mismatch error a

44、nd is much less expensive than the indoor test method because it avoids the use of very expensive solar simulators. However, obtaining an accurate and repeatable P maxmatrix using the outdoor method over time (several months or years) would be extremely challenging. This standard consists of four pa

45、rts: IEC 61853-1: Irradiance and temperature performance measurements and power rating, which describes requirements for evaluating PV module performance in terms of power (watts) rating over a range of irradiances and temperatures; IEC 61853-2: Spectral responsivity, incidence angle, and module ope

46、rating temperature measurements, which describes test procedures for measuring the effect of varying angle of incidence and sunlight spectra as well as the estimation of module temperature from irradiance, ambient temperature, and wind speed; IEC 61853-3 1 : Energy rating of PV modules, which descri

47、bes the calculations for PV module energy (watt-hours) ratings; and IEC 61853-4 2 : Standard reference climatic profiles, which describes the standard time periods and weather conditions that can be used for the energy rating calculations. Included in the IEC 61853 series of standards are: test meth

48、ods designed to map module performance over a wide range of temperature and irradiance conditions (IEC 61853-1); test methods to determine spectral responsivity, incidence angle effects and the module operating temperature all as functions of ambient conditions (IEC 61853-2); methods for evaluating

49、instantaneous and integrated power and energy results including a method for stating these results in the form of a numerical rating (IEC 61853-3); and definition of reference irradiance and climatic profiles (IEC 61853-4). IEC 61853-1 describes requirements for evaluating PV module performance in terms of power (watts) rating over a range of irradiances and temperatures. IEC 61853-2 describes procedures for measuring
