It has been found that the accumulation of dust on photovoltaic panels can significantly reduce their output resulting in an increase in the cost of the electricity. There are several methods used to clean the solar PV panel. The PV cleaning system presented in this research paper is a straightforward alternative that addresses this issue effectively. This present work aimed to compare the time required for cleaning of solar pv panel system with manual and robotic technique. In the present study, an automated solar PV module cleaning system has been developed. The proposed designprovides a durable, dependable, and automated cleaning mechanism for solar power plants. The robotic cleaning system was found less time consuming compared to the manual cleaning of the solar PV panel. It is found to be very difficult for manual cleaning to clean solar plants of higher capacity. Depending upon the size of the solar PV panel, it is found to be difficult to clean all surface area of the solar PV panel at the time of manual cleaning. The robotic cleaning system for a solar PV panel is found to be very effective for the solar PV power plants of higher capacity and located at remote locations. [ABSTRACT FROM AUTHOR]
