BS EN 62670-1:2014 PDF

1   Scope This part of IEC 62670 defines standard conditions for assessing the power produced by CPV systems 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 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.
