Advanced measurement techniques to characterize the near-specular reflectance of solar mirrors 2019 Access copy available to the general public Unrestricted The precise measurement of the reflected energy from a solar reflector to the receiver is a challenging task because of its dependency on three different parameters: the wavelength of the incident light, its incidence angle and the acceptance angle of the receiver. Up to today, the commonly employed measurement equipment is not able to fully characterize the mirrors in the required range of parameters which is relevant for CSP. Within this work, four reflectometers were upgraded to overcome the current drawbacks. A Round Robin test among the different characterization methods has been carried out on four reflector materials. The conclusions drawn from the comparison of the measurement results help to improve the current SolarPACES Reflectance Guideline. info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.19 2019 Physics and Astronomy (miscellaneous) 2019 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Fernández-García, A.
