prEN IEC 63387-1:2025

This document specifies the requirements for evaluating CPV/PV hybrid module performance in terms of power rating. Standard conditions for assessing the power produced by the module and the procedures to measure the power as a function of AOI, irradiance, and temperature are defined. A methodology for determining a set of characterization parameter values for the hybrid CPV/PV module (FoV) is also included. In order to compare the performance of different hybrid CPV/PV modules whose output is discontinuous and time-dependent the concept of effective nominal power is introduced. This standard is written to be applicable to CPV/PV hybrid modules which include both solar cells designed to collect concentrated light (CPV cells array) and solar cells designed to collect diffuse or global light (PV cells array), the last ones, with bifacial or monofacial illumination. This document applies for hybrid CPV/PV modules with geometrical concentration ratio >3x to CPV cells. For lower geometrical concentration ratio (≤ 3x), the IEC 60904-1 and IEC 61853 series apply.
