UL SUBJECT 4730

Abstract

This outline identifies the required information on the production and measurement tolerances of nameplate rating of flat plate photovoltaic (PV) modules. <br>This outline identifies five rating conditions under which the performance parameters of PV modules shall be reported. <br>This outline identifies a statistical method to determine the number of samples required for the power rating measurements. <br>The samples shall be drawn at random without regard to their quality as defined in the Standard for Sampling procedures and tables for inspection by attributes, ANSI/ASQ Z1.4 (ANSI/ASQ, 2003). <br>The power rating measurements shall be performed. <br>This outline requires that the nameplate on the PV module carry the minimum required information identified in this outline. <br>This outline requires that the datasheet supplied by PV module manufacturers carry the minimum required information identified in this outline. <br>Every model/type label rating shall be tested to this outline. For the purpose of this outline, a model/type is defined as modules that have a nameplate rating within 5% of the tested modules in accordance with this outline. <br>This outline does not specify annual sampling frequency. <br>This outline does not apply to concentrator PV modules.
