Resumen: 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.
