| Popis: | 26th European Photovoltaic Solar Energy Conference and Exhibition; 778-781 Procedures applicable to concentrating solar collectors to determine how they modify spectrally and spatially the sun direct radiation are described in this paper. We use a radiometric apparatus provided with two cavities for light integration and attenuation (DCR) and coupled with an external spectrometer for spectral measurements. To measure spatial light distribution we use a CCD camera with its data acquisition system, a set of neutral filters, a receiver and the collector itself which has to be characterized. Finally, a heat flux sensor based on an inverse heat transfer method (IHTM) is being developed for the estimation of concentrated radiative heat flux by means of temperature measurements. The overall apparatus should be able to characterize a concentrated sunlight flux up to a concentration factor of 1000 X. |
