Soiling on Heliostats Estimated by Shaded and Unshaded Scatterometry
Topic: Field DeploymentPrincipal Investigator: Derek Schulte derek@dkadesign.biz
DKA Design LLC, in partnership with Heliogen, will develop a centralized, low-labor method to estimate the cleaning increase in mirror specular reflectance. By analyzing the different intensities of reflected light from shaded and unshaded regions of each selected and deliberately tilted (“off sun”) heliostat mirror, the amount of soiling thereof will be determined utilizing imaging data from existing and centralized heliostat control system sensors.
