IEC 61829:2015 specifies procedures for on-site measurement of flat-plate photovoltaic (PV) array characteristics, the accompanying meteorological conditions, and use of these for translating to standard test conditions (STC) or other selected conditions. This new edition includes the following significant technical changes with respect to the previous edition:
- it addresses many outdated procedures;
- it accommodates commonly used commercial I-V curve tracers;
- it provides a more practical approach for addressing field uncertainties;
- it removes and replaces procedures with references to other updated and pertinent standards, including the IEC 60904 series, andIEC 60891.
