Development of a control system for automatic surface cleaning device for solar photoelectric panels

The article presents the current state and development prospects of the use of photovoltaic solar panels in the world and in Uzbekistan, as well as an analysis of foreign researchers’ scientific studies on cleaning the surfaces of photovoltaic solar panels and the factors affecting their efficiency. It provides information about photovoltaic solar power plants installed in Uzbekistan and the innovative scientific research carried out by the “Green Energy” Scientific Innovation Center under Bukhara State Technical University, where reliable cleaning devices for removing various types of contamination from photovoltaic solar panel surfaces under continental climate conditions have been developed. Automatic control systems for cleaning devices, water-based and waterless cleaning methods are proposed. Over the course of one month, the output power of two contaminated and two daily cleaned photovoltaic solar panels was compared. According to the experimental results, when the dust density varied from 0 to 22 g/m², efficiency was found to decrease by up to 26%. The article also presents the general structure of the proposed device, information about the DC motors installed in the device, as well as the schematic diagram, algorithm, and operating principle of the automatic control system.
