Abstract

The Amonix system is a high concentration PV system that utilizes acrylic Fresnel lenses to focus the sun’s rays onto dispersed PV cells. The Fresnel lenses become soiled with dust over time which decreases power performance. Because of the effect soiling has upon the system performance, Amonix and the University of Nevada, Las Vegas (UNLV) have defined a long term soiling investigation and cleaning methodology. The test and measurement procedure for determining Fresnel lens soiling rate characterization is discussed. Lens soiling rate data is presented for different sites that show the soiling rate is a direct function of the angle of the lens. This paper also discusses the test and measurement procedure of the first phase of an on-going Fresnel lens cleaning investigation. An assessment of the soiling rate upon power production is also presented.
