Solar Panel Cleaning Robot

Solar panel efficiency is often reduced by dust and debris accumulation, making regular cleaning essential but challenging. This research presents an automated solar panel cleaning robot controlled via Wi-Fi using a NodeMCU microcontroller. Equipped with DC motors for movement and sweeping, and a water pump system, the robot ensures thorough cleaning. Testing showed a 15-20% increase in solar panel energy output post-cleaning. The system demonstrated reliable operation and responsive remote control via a web interface. This solution is suitable for various applications, including residential rooftops, commercial solar farms, and remote off-grid systems, enhancing solar maintenance efficiency, and reducing costs.
