1、Designation:E284813Standard Test Method forReporting Photovoltaic Non-Concentrator SystemPerformance1This standard is issued under the fixed designation E2848;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.
2、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 This test method provides measurement and analysisprocedures for determining the capacity of a specific photovol-taic system built in a p
3、articular place and in operation undernatural sunlight.1.2 This test method is used for the following purposes:1.2.1 acceptance testing of newly installed photovoltaicsystems,1.2.2 reporting of dc or ac system performance,and1.2.3 monitoring of photovoltaic system performance.1.3 This test method sh
4、ould not be used for:1.3.1 testing of individual photovoltaic modules for com-parison to nameplate power ratings,1.3.2 testing of individual photovoltaic modules or systemsfor comparison to other photovoltaic modules or systems,1.3.3 testing of photovoltaic systems for the purpose ofcomparing the pe
5、rformance of photovoltaic systems located indifferent places.1.4 In this test method,photovoltaic system power isreported with respect to a set of reporting conditions(RC)including:solar irradiance in the plane of the modules,ambienttemperature,and wind speed(see Section 6).Measurementsunder a varie
6、ty of reporting conditions are allowed to facilitatetesting and comparison of results.1.5 This test method assumes that the solar cell temperatureis directly influenced by ambient temperature and wind speed;if not the regression results may be less meaningful.1.6 The capacity measured according to t
7、his test methodshould not be used to make representations about the energygeneration capabilities of the system.1.7 This test method is not applicable to concentratorphotovoltaic systems;as an alternative,Test Method E2527should be considered for such systems.1.8 The values stated in SI units are to
