Abstract

The soiling level of heliostat mirrors in Concentrated Solar Power (CSP) fields is one of the key factors that significantly influences optical efficiency. While several methods of monitoring heliostats soiling levels have been developed, it remains challenging to determine heliostats soiling levels quickly and non-intrusively with large area scanning. We have developed a method based on polarimetric imaging to accomplish this goal, using the natural light’s polarization information and ray tracing calculations. With the flexibility to be integrated into a UAV-based imaging system or portable imaging setup, this method holds the potential of deployment to any CSP field for mirror soiling detection high efficiency and accuracy.
