This paper deals with the performance of multicolour photothermal converters with four conversion units. The power station consists in a combination multicolor converter‐thermal engine. The influence of the solar radiation concentration ratio on the system performance is outlined. The effect of the sun's zenith angle is also discussed. The spectral distributions of optimum collector and radiator temperatures and the optimum temperature differences between the working fluid and the collector and radiator, respectively, are shown. © 1998 John Wiley & Sons, Ltd.
