The Institute for Standardization of Bosnia and Herzegovina, through its Technical Committee BAS/TC 56, Conventional and alternative sources of electrical energy, has adopted, by translation method, the second edition of BiH standard BAS EN 61853-1:2024, Photovoltaic (PV) module performance testing and energy rating - Part 1: Irradiance and temperature performance requirements and power rating. This standard is a translation of the English version of EN 61853-1:2011.

BAS EN 61853-1:2024, which is part of the IEC 61853 series, describes requirements for evaluating PV modules performance in terms of power (watts) rating over a range of irradiances and temperatures. IEC 61853-2 defines measurement procedures for measuring the effects of angle of incidence of the irradiance of the output power of the device, the estimation of module temperature from irradiance, ambient temperature and wind speed, and impact of spectral responsivity on module performance. IEC 61853-3 describes the calculations of PV module energy (watt-hours) ratings. IEC 61853-4 describes the standard time periods and weather conditions that can be utilized for calculating energy ratings.

The object of this part of IEC 61853 is to define a testing and rating system which provides the PV module power (watts) at maximum power operation for a set of defined conditions. A second purpose is to provide a full set of characterization parameters for the module under various valuer of irradiance and temperature. This set of measurements is required in order to perform the module energy rating described in IEC 61853-3.

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