Surface Damage to Mirrors used in Concentrated Solar Power Plants

by Jincy Varughese

In Concentrated Solar Power (CSP) plants, 30% of investment costs are attributed to the installation, maintenance, and replacement of mirrors. In order to ensure high yield at a CSP plant, the solar specular reflectance of these mirrors must be maintained at high standards. However, several environmental factors such as temperature, humidity, and windstorms contribute to the degradation of these panels. The latter, is of particular interest to Karim and a team of researchers from Morocco who, over the course of two years, evaluated the effect of windstorms on surface erosion of CSP mirrors.
