It is written to be applicable to all concentrator PV techno

18、logies that have a geometric concentration ratio greater than 3X and require tracking. Included in the IEC 62670 series of standards are definitions of the standard conditions and methods to be used for assessing CPV performance. IEC 62670-1 defines a standard set of conditions so that power ratings

19、 noted on data sheets and nameplates will have a standard basis. IEC 62670-2 describes an on-sun, measurement-based method for determining the energy output and performance ratio for CPV arrays, assemblies and power plants. IEC 62670-3 describes methods for providing a CPV power assessment under the

20、 sets of standard conditions, enabling assessments both indoors and outdoors. BS EN 62670-1:2014 6 62670-1 IEC:2013 PHOTOVOLTAIC CONCENTRATORS (CPV) PERFORMANCE TESTING Part 1: Standard conditions 1 Scope This part of IEC 62670 defines standard conditions for assessing the power produced by CPV syst

21、ems and their photovoltaic subcomponents. The object of this part of IEC 62670 is to define a consistent set of conditions so that power ratings noted on data sheets and nameplates will have a standard basis. Two sets of conditions are included to characterize: a) operating conditions that represent

22、 on-sun performance relative to commonly measured meteorological conditions, and b) test conditions that represent performance when the module is in a readily reproducible environment. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document an
