Influence of soiling on CSP mirrors in a mountain climate in Morroco.

Concentrated Solar Power (CSP) technology has known a huge evolution in the last decades. Reflector is one of the most strategic components in CSP plant and soiling is one of the most deleterious parameters that should deeply understood during the choice of the plant localization. The main aim of this analysis is to evaluate the impact of soiling on reflectors' reflectance in a mountain climate as Morocco is launching a new CSP plant in Midelt region (Middle Atlas mountain). Through this analysis, it is shown that correlation of climate parameters like precipitations and wind is the key to enhance the understanding of the behavior of soiling in a mountain region. Up to 57% reflectance loss is recorded during summer periods while not less than 10% reflectance is registered during all periods of analysis. [ABSTRACT FROM AUTHOR]
