Paper Abstract

This paper covers some preliminary results of research on the environmental responses of solar reflective surfaces. Although this paper provides information for the selection and evaluation of solar reflective surfaces in general, the work was performed for dish concentrator applications. Over a dozen types of glass, metallic and polymeric reflective surfaces have been exposed to the environment in Southern California. Data fran three locations were obtained: two sites at Pasadena and one site at Goldstone, near Barstow. Qualitative effects of contamination buildup are described. Evaluation of clean surfaces of the same three types of surfaces was performed under a separate program. Modeling of dust buildup and removal of worst-case data based upon six nationwide sites is presented and compared to Albuquerque, New Mexico soiling data. These data are useful in providing insight to determine the effects of soiling buildup to be expected in the design of concentrators at various geographical locations. They are also used to determine the method and frequency of washing requirements for optimum reflector performance.
