The International Energy Agency's Photovoltaic Power Systems Programme (IEA-PVPS) says dust, pollution, and debris on solar panels reduce output by 4% to 7% worldwide, costing the industry billions of euros annually and making tailored mitigation increasingly urgent. In a typical environment, you can expect around a 20% drop in power output from dust buildup alone. That makes dust the second most significant factor affecting solar. Dust accumulation on photovoltaic (PV) modules is a major factor contributing to reduced power output, lower efficiency, and accelerated material degradation, particularly in arid and industrialized regions. This study presents a comprehensive review and analysis of the influence of dust deposition. This review comprehensively examines the impact of dust on PV performance, highlighting factors such as surface roughness of PV module, panel tilt angle, seasonal variations, wind dynamics, and dust composition. Furthermore, the review assesses various dust mitigation strategies, including manual. The dust collected from the solar module in USA and Egypt, it was observed that 75% of the dust was quartz silicates (SiO2) and 20% was feldspars (NaAlSi3O8, CaAlSi3O8, KAlSi3O3).
