The Institute for Standardization of Bosnia and Herzegovina, through its Technical Committee BAS/TC 56, Conventional and alternative sources of electricity, has published the second edition of BiH standard BAS EN IEC 61853-4:2023, Photovoltaic (PV) module performance testing and energy rating - Part 4: Standard reference climate profiles, which is a translation of the English version of EN IEC 61853-4:2018.

BAS EN IEC 61853-4:2023 is part of the IEC 61853 series that describes the standard reference climatic profiles used for calculating energy ratings.

IEC 61853-1 describes requirements for evaluating PV module performance in terms of determining the power (watts) rating. IEC 61853-2 describes test procedures for determining module temperature from irradiance, ambient temperature and wind speed, a method for measuring angle of incidence effects, and spectral responsivity. IEC 61853-3 describes the calculation of PV module energy rating values, using the data from IEC 61853-1, IEC 61853-2 and IEC 61853-4.

The defined conditions contained within this document shall be used in IEC 61853-3 to obtain an energy rating. A fixed number (6) of standard reference climatic profiles are tabulated, representative of global regions relevant for the application of photovoltaics. The irradiance and ambient temperature data are representative of typical conditions over each region, but are to be considered as average values. The spectrally resolved irradiances are derived from satellite data.

The original texts of the standard were prepared by the International Technical Committee IEC TC 82, Solar photovoltaic energy systems.
