Summary of Test

    14、 Method4.1 Determining the performance of a photovoltaic moduleor system under natural sunlight consists of measuring themaximum power over a range of irradiance and air tempera-ture.4.2 Amultiple linear regression is used to rate the maximumpower3at standard concentrator reporting conditions, defin

    15、edas To= 20C, vo=4ms-1, Eo= 850 Wm-2.4.2.1 A direct normal irradiance of 850 Wm-2was selectedfrom a resource assessment study4that showed when the globalnormal solar irradiance is near the 1000 Wm-2used in ratingflat-plate photovoltaic modules, the direct normal irradiance isabout 850 Wm-2.4.3 The a

    16、ctual test data and the performance results are thenreported.5. Significance and Use5.1 It is the intent of this test method to provide a recog-nized procedure for testing and reporting the electrical perfor-mance of a photovoltaic concentrator module or system.5.2 If an inverter is used as part of

    17、the system, this testmethod can provide a dc or ac rating or both. The dc or acrating depends on whether the inverter input or output ismonitored.5.3 The test results may be used for comparison among agroup of modules or systems from a single source. They alsomay be used to compare diverse designs,

    18、such as products fromdifferent manufacturers. Repeated measurements of the samemodule or system may be used for the study of changes indevice performance over a long period of time or as a result ofstress testing.5.4 The test method is limited to modules and systemswhere the concentrated irradiance

    19、on the component cells isgreater than 5000 Wm-2at Eo. This limitation is necessarybecause the total irradiance is measured with a radiometer witha field of view less than 6 and because the correlation betweenthe direct irradiance and the power produced decreases withincreasing concentrator field of

    20、view.5.5 This test method assumes that the regression equationaccurately predicts the concentrator performance as a functionof total irradiance with a fixed spectral irradiance, wind speed,and air temperature. The spectral distribution will be seasonaland site specific because of optical air mass, w

    21、ater vapor,aerosols, and other meteorological variables.6. Apparatus6.1 Test FixtureA platform that maintains an incidenceangle to the sun of less than 0.5. If the manufacturersspecifications require more accurate tracking than 0.5 inci-dence angle, the manufacturers specifications should be fol-low

    22、ed. Concentrator systems shall be tested as installed.6.2 Air Temperature Measurement EquipmentThe instru-ment or instruments used to measure the temperature of the airshall have a resolution of at least 0.1C, and shall have a totalerror of less than 61C of reading. The instrument sensorshould be be

    23、tween 1 and 10 m upwind from the geometricalcenter of the receiver and be mounted at least 2 m above theground. Further details on air temperature measurements canbe found in Practice D 6176.6.3 Irradiance Measurement EquipmentA secondary ref-erence pyrheliometer calibrated according to Test MethodE

    24、 816.6.4 Wind Speed Measurement EquipmentThe instrumentused to measure the wind speed should have an uncertainty ofless than 0.5 ms-1. The instrument should be between 1 and 20m from the geometrical center of the receiver and be mountedat least 2 m above the ground. Because there are many possiblesy

    25、stem configurations, care should be taken to minimize effectson the instrument readings from the system or nearby ob-stacles.Averaging readings from multiple instruments for largesystems may be required.6.5 Power Measurement EquipmentExamples of accept-able instrumentation to measure the output powe

    26、r of themodule or system under test include:6.5.1 Current-voltage measurement instrumentation re-quired by Test Methods E 1036,6.5.2 ac or dc current and voltage measurement instrumen-tation, and6.5.3 ac or dc power meter.7. Procedure7.1 If required, mount the module or system to be rated onthe trac

    27、king platform7.2 Connect the module or system to be rated to the powermeasurement equipment.7.3 Measure the direct solar irradiance E, air temperatureTa, and the wind speed v. The average wind speed for 5 minpreceding the power measurement should not exceed 5 ms-1.The data should be collected within

    28、 610C of To.7.4 Measure the maximum power according to 7.2.9 of TestMethods E 1036. If an inverter is part of the system, measurethe ac or dc output power of the system. If the powermeasurement time is longer than 10 s, verify that the irradiancevariation is less than 61% and the wind speed is less

    29、than 5ms-1.7.5 Reject data when there are visible clouds within 10 ofthe sun, or within the field-of-view of the device under test,whichever is greater7.6 Repeat 7.3 through 7.5 at least 20 times. For best resultsthe irradiance data should be evenly distributed in time andtemperature and E should be

    30、 greater than 750 Wm-2.8.
