In this modern era, the installation of renewable energy plants is a vital question for the safety of the cities and humans against pollution, and this pollution is increasing as the population of the world is increasing randomly, due to which human needs are not being met by traditional fossil energy. That’s why we have to install the renewal energy plant so that the need gets met. Firstly, dust accumulation diminishes the system's ability to absorb sunlight effectively. This reduction in light absorption directly leads to a decrease in the system's energy output. Additionally, the presence of dust particles can interfere with the flow of photons to the solar cells, hindering the conversion of sunlight into electricity. This decrease in conversion efficiency further increases the energy loss. Dust can also create localized shadows on the PV panel's surface. These shadows lead to decreased energy production in specific areas, potentially causing hotspots that could result in long-term damage to the panels. Moreover, dust is part of a broader category of soiling losses, which includes various contaminants like pollen and bird droppings. Collectively, these contaminants reduce the energy output of the PV system, impacting its overall efficiency. In this review paper, we are dealing with the accumulation of dust on photovoltaic (PV) panels, which can significantly reduce the energy efficiency of a solar PV system. Dust and dirt particles that settle on the surface of PV panels act as barriers, limiting the amount of sunlight that can reach the solar cells. As a result, the system's energy production decreases. This reduction in energy efficiency can be attributed to several factors.
