Design and Implementation of an Automated Dry Solar-Panel Cleaning System

This paper presents a full design and implementation process of a low-cost system that is used to clean solar panels automatically without using liquids. The system utilizes two microfiber brushes driven by two separate DC motors to clean the panels. Two more DC motors are used to control the machine movement. In addition, ultrasonic sensors are used to detect the edges of the solar panel to stop the motors at the proper time. The system also includes four relays that are connected to a microcontroller, which is placed at the gear box, to control the sensors, motors, and the brushes movement. Infra-red (IR) receiver, Infra-red (IR) remote and a 5V relay are used to switch on and off the system. The system is powered by a 12V lead acid DC battery.
