Abstract: Considerable loss of energy in the solar fields of Concentrating Solar Power (CSP) systems is caused by accumulated dust on the surface of the solar reflectors deployed in dusty arid and semi-arid zones. The monthly dynamics of changes in reflectance of the widely used second-surface silvered mirrors and innovative candidate aluminum materials under different site conditions can be useful for finding out the soiling characteristics of these mirror materials. Knowledge of the cumulative soiling of candidate mirror materials is essential to understanding their behavior at sites where cleaning is unavailable and water is scarce.
