Design and Development of an Automatic Robotic Cleaning System for PV Panels Abstract Cleaning of solar panels is very important in order to produce and deliver the maximum amount of energy to the grid. The effect of dirt and dust on the performance of solar panels depends on various factors and always needs to be estimated or evaluated for individual situations. So The main objective of this project is to increase the performance of solar panels by using a robot to clean it automatically without need for human . PID Controller It makes the robot goes straight The Robot cleaning path Control the cleaning robot wirelessly using Xbee The user is able to control the cleaning robot wirelessly from a PC via Xbee modules. Accelerometer Flowchart of searching path of the robot It is an electromechanical device that will measure acceleration forces. The developed cleaning robot of PV panels Results: The X Y Z output serial port signals of the ARDUINO-MIGA coming from the accelerometer Conclusion A control strategy for the Robotic Vacuum Cleaner has been designed and tested. It has been proved experimentally that the robot can traverse on inclined surfaces (tilt angle 10°) without any difficulty. If battery level falls below a threshold, it is confirmed that the robot returns to the docking station and charges itself automatically. Using more powerful batteries, vacuum motors and gripper wheels would be helpful in implementing the robot on a larger scale. Addition of a gyroscope to the navigation control of this system would improve the feedback mechanism. Implementing machine learning concepts would enable the robot to find preset values by itself accurately, thus making it fully autonomous and a step closer to be released as a commercial product.
