This project presents an automatic solar panel cleaning module using Arduino, Bluetooth control, DC motor with motor driver, and a 2-channel relay module. Dust and dirt on solar panels reduce their efficiency and power output. To solve this problem, the system uses a small motor-driven wiper/brush mechanism to clean the panel surface. The Arduino acts as the main controller and operates the motor through the motor driver and relay module. The system can be controlled wirelessly from a smartphone using Bluetooth, allowing users to start or stop the cleaning process raemotely. This project helps maintain panel efficiency, reduces manual cleaning effort, increases safety, and supports continuous power generation in solar plants and rooftop systems.
