Designation:E103615Standard Test Methods forElectrical Performance of Nonconcentrator TerrestrialPhotovoltaic Modules and Arrays Using Reference Cells1This standard is issued under the fixed designation E1036;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 These test methods cover the electrical performance ofphotovoltaic modules and arrays under natural or simulatedsunlight using a calibrated reference cell.1.1.1 These test methods allow a reference module to beused instead of a reference cell provided the reference modulehas been calibrated using these test methods against a cali-brated reference cell.1.2 Measurements under a variety of conditions are al-lowed;results are reported under a select set of reportingconditions(RC)to facilitate comparison of results.1.3 These test methods apply only to nonconcentrator ter-restrial modules and arrays.1.4 The performance parameters determined by these testmethods apply only at the time of the test,and imply no past orfuture performance level.1.5 These test methods apply to photovoltaic modules andarrays that do not contain series-connected photovoltaic mul-tijunction devices;such module and arrays should be testedaccording to Test Methods E2236.1.6 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.7 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2E691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test MethodE772 Terminology of Solar Energy ConversionE927 Specification for Solar Simulation for PhotovoltaicTestingE941 Test Method for Calibration of Reference Pyranom-eters WithAxis Tilted by the Shading Method(Withdrawn2005)3E948 Test Method for Electrical Performance of Photovol-taic Cells Using Reference Cells Under Simulated Sun-lightE973 Test Method for Determination of the Spectral Mis-match Parameter Between a Photovoltaic Device and aPhotovoltaic Reference CellE1021 Test Method for Spectral Responsivity Measurementsof Photovoltaic DevicesE1040 Specification for Physical Characteristics of Noncon-centrator Terrestrial Photovoltaic Reference CellsE1125 Test Method for Calibration of Primary Non-Concentrator Terrestrial Photovoltaic Reference Cells Us-ing a Tabular SpectrumE1362 Test Method for Calibration of Non-ConcentratorPhotovoltaic Secondary Reference CellsE2236 Test Methods for Measurement of Electrical Perfor-mance and Spectral Response of Nonconcentrator Multi-junction Photovoltaic Cells and ModulesG173 Tables for Reference Solar Spectral Irradiances:DirectNormal and Hemispherical on 37 Tilted Surface3.Terminology3.1 DefinitionsDefinitions of terms used in these testmethods may be found in Terminology E772.3.2 Definitions of Terms Specific to This Standard:3.2.1 nominal operating cell temperature,NOCT,nthetemperature of a solar cell inside a module operating at anambient temperature of 20C,an irradiance of 800 Wm2,andan average wind speed of 1 ms1.3.2.2 reporting conditions,RC,nthe device temperature,total irradiance,and reference spectral irradiance conditionsthat module or array performance data are corrected to.1These test methods are under the jurisdiction of ASTM Committee E44 onSolar,Geothermal and Other Alternative Energy Sources and are the directresponsibility of Subcommittee E44.09 on Photovoltaic Electric Power Conversion.Current edition approved Feb.1,2015.Published March 2015.Originallyapproved in 1985.Last previous edition approved in 2012 as E1036 12.DOI:10.1520/E1036-15.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 3.3 Symbols:3.3.1 The following symbols and units are used in these testmethods:rtemperature coefficient of reference cell ISC,C1,current temperature coefficient of device under test,C1,(E)voltage temperature function of device under test,C1,Ccalibration constant of reference cell,Am2W1,Cadjusted calibration constant of reference cell,Am2W1,CfNOCT Correction factor,C,(T)voltage irradiance correction function of device undertest,dimensionless,TNOCT cell-ambient temperature difference,C,Eirradiance,Wm2,Eoirradiance at RC,Wm2,FFfill f
