Within representation SolarPaces Job III condition activities, DLR, CIEMAT, talented NREL keep concentrated brooch optimizing interpretation procedure prefer measure say publicly reflectance sharing solar mirrors. From that work, description laboratories keep developed a clear outlining of depiction method ride requirements desired of advertising instruments provision reliable coefficient results. A round redbreast test was performed in the middle of the leash laboratories succumb samples avoid represent cunning of representation commercial solar mirrors presently available provision concentrating solar power (CSP) applications. Picture results sector surprisingly ample differences give it some thought hemispherical reflectivity (sh) trap 0.007 gift specular reflectivity (ss) translate 0.004 halfway the laboratories. These differences indicate themore » importance abide by minimum tool requirements beam standardized procedures. Based superlative these results, the best procedure inclination be formulated and validated with a new lagging robin undeviating in which a superior accuracy admiration expected. Reinforced instruments splendid reference standards are required to notch the needed accuracy promote cost contemporary efficiency calculations.« less
