3MODULE SPECIFICATIONS Module specifications are shown inTable 1 and Figure 1. (Electricalspecifications, mechanical specifica-tions, module dimensions)1) Rated electrical characteristics arewithin the range of –5% to +10% ofthe values measured at StandardTest Conditions (STC). STC condi-tions are; Irradiance of 1000W/m2,25°C cell temperature, AM1.5 andsolar spectral irradiance per IEC60904-3. Note: At the time of ship-ment, Panasonic guarantees theoutput level of its modules to be -0/+10% against Rated Power in SPECI-FICATIONS based on factory inspec-tion at STC conditions.2) Under real conditions, a photovolta-ic module may experience condi-tions that produce more currentand/or voltage than reported atStandard Test Conditions. There-fore, the Isc value of modulesshould be multiplied by a factor of1.25 to determine ampacity. Anadditional factor of 1.25 may berequired for sizing conductors, fus-es, disconnects, etc. Please refer tosection 690.8 of the National ElectricCode (NEC) for guidelines. The Vocmust be factored according to thelowest recorded ambient tempera-ture recorded for the locationwhere the modules will be installed.Please refer to section 690.7 of theNEC for more information regardingvoltage temperature factors.MECHANICAL LOADING The modules should be mounted atthe four (4) quarter points by themeans shown in Figure 1. This method offers a maximum loadshown as “Mount Location andLoad Resistance” in Figure 1 in astatic state on the module surface. Note: This mechanical loading valuewas tested using the mounting de-vice specified in section “MODULEINSTALLATION” As UL Certified Load Ratings, thismodule meets design loads as be-low.1) Positive load with Long framemounting・ 33 psf (0-450mm range from edge･ 75 psf (230-380mm range from edge)2) Negative load with Long framemounting･ 33 psf (0-450mm range from edge･ 61 psf(230-380mm range from edge)･ 75 psf (230-345mm range from edge)3) Positive load with Short framemounting･ 33 psf (0-250mm range from edge)4) Negative load with Short framemounting･ 33 psf (0-250mm range from edge)FrontFigure 1.
