Hybrid CPV/PV modules: General characteristics and measurement procedures - Part 1: Performance measurements and power rating - Irradiance and temperature

Scope

IEC 63387-1:2026 specifies the methods 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 described. 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 document is 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 latter with bifacial or monofacial illumination. This document applies to hybrid CPV/PV modules with a geometrical concentration ratio > 3x for the CPV cells. For lower geometrical concentration ratio (≤ 3x), the IEC 60904-1 [11] and IEC 61853 series [9] apply.
