Abstract: One of the most popular techniques of renewable energy generation is the installation of photovoltaic (PV) systems using sunlight to generate electrical power. In this paper we review that the effect of dust accumulation on the solar panel naturally. This paper provides a comprehensive overview of soiling problems, primarily those associated with ‘‘dust’’ (sand) and combined dust-moisture conditions that are inherent to many of the most solar-rich Geographic locations worldwide. We review and evaluate key contributions to the understanding performance effects. The degradation of PV performance due to the deposition of different pollutant types and accumulation has been investigated. The results show that the reduction in PV voltage and power is strongly depends on pollutant type and deposition level. This paper provides a detailed review of the effect of dust accumulation on PV panel. The presented detailed overview will be useful to people working on theory, design and/or application of photovoltaic based electricity generation systems.
