Modeling of Dust Deposition Affecting Transmittance of PV Modules

Abstract

The dust deposition significantly influences the energy gained from the solar power system. The dust deposition of PV modules is decided many factors, such as weather, location, tilt angle, and so on. This paper focuses on the influence factors of the PV modules. In order to realize the relationship between the dust deposition and the sunlight transmittance of the solar PV module, improved models considering the effect of incident angle and tilt angle are developed based on the overlay model. Then simulation with the improved models is conducted to analyze the characteristics of each model.
