5.1 It is the intent of these procedures to provide recognized methods for testing and reporting the electrical performance of photovoltaic modules and arrays.
5.2 The test results may be used for comparison of different modules or arrays among a group of similar items that might be encountered in testing a group of modules or arrays from a single source. They also may be used to compare diverse designs, such as products from different manufacturers. Repeated measurements of the same module or array may be used for the study of changes in device performance.
5.3 Measurements may be made over a range of test conditions. The measurement data are numerically translated from the test conditions to standard RC, to nominal operating conditions, or to optional user-specified reporting conditions. Recommended RC are defined in Table 1.
| Total Irradiance, Wm???2 | Spectral Irradiance | Device Temperature, |
Standard reporting conditions | 1000 | 25 | |
Nominal operating conditions | 800 | ... | NOCT |
