1. The document discusses the development of an automatic solar panel cleaning robot using Internet of Things (IoT) technology. Accumulation of dust and dirt on solar panels reduces their efficiency and power output. 2. It reviews different methods for cleaning solar panels and proposes a simple, useful cleaning device with a novel IoT-based cleaning system architecture. This system would automatically clean solar panels to maintain high efficiency. 3. The system would consist of sensors to detect dust levels on panels and actuators to trigger automated cleaning. This is expected to provide about 30% more energy output compared to uncleaned panels.
