The reflectance efficiency of heliostat mirror surfaces is a critical parameter in the central tower concept for conversion of solar energy. Reflectance efficiency was measured on silver coated surfaces and on second-surface mirrors of float and sheet glass for comparison in a solar heliostat. Abrasion tests were conducted to determine the effect of impingement of sand particles on the reflectance of the heliostat mirror. Washing studies were performed to identify the most effective solution and cleansing procedure for the heliostat surfaces.
