1.1This test method provides measurement and analysis procedures for determining the capacity of a specific photovoltaic system built in a particular place and in operation under natural sunlight.

1.2This test method is used for the following purposes:

1.2.1Acceptance testing of newly installed photovoltaic systems,

1.2.2Reporting of dc or ac system performance, and

1.2.3Monitoring of photovoltaic system performance.

1.3This test method should not be used for:

1.3.1Testing of individual photovoltaic modules for comparison to nameplate power ratings,

1.3.2Testing of individual photovoltaic modules or systems for comparison to other photovoltaic modules or systems, and

1.3.3Testing of photovoltaic systems for the purpose of comparing the performance of photovoltaic systems located in different places.

1.4In this test method, photovoltaic system power is reported with respect to a set of reporting conditions (RC) including solar irradiance in the plane of the modules, ambient temperature, and wind speed (see Section 6). Measurements under a variety of reporting conditions are allowed to facilitate testing and comparison of results.

1.5This test method assumes that the solar cell temperature is directly influenced by ambient temperature and wind speed; if not the regression results may be less meaningful.

1.6The capacity measured according to this test method should not be used to make representations about the energy generation capabilities of the system.

1.7This test method is not applicable to concentrator photovoltaic systems; as an alternative, Test Method E2527 should be considered for such systems.

1.8The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.9This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.10This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
