ASTM E2527-09 PDF

1.1 This test method covers the determination of the electrical performance of photovoltaic concentrator modules and systems under natural sunlight using a normal incidence pyrheliometer.

1.2 The test method is limited to module assemblies and systems where the geometric concentration ratio specified by the manufacturer is greater than 5.

1.3 This test method applies to concentrators that use passive cooling where the cell temperature is related to the air temperature.

1.4 Measurements under a variety of conditions are allowed; results are reported under a select set of concentrator reporting conditions to facilitate comparison of results.

1.5 This test method applies only to concentrator terrestrial modules and systems.

1.6 This test method assumes that the module or system electrical performance characteristics do not change during the period of test.

1.7 The performance rating determined by this test method applies only at the period of the test, and implies no past or future performance level.

1.8 This 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 and health practices and determine the applicability of regulatory limitations prior to use.
