Our idea for the solar panel cleaning drone revolves around developing an innovative solution to efficiently clean solar panels, particularly those in challenging environments such as floating solar installations. The drone will be equipped with advanced technology, including high-pressure nozzles and a tethered water supply system, allowing it to clean panels without imposing additional weight or safety risks. This solution aims to address the inefficiencies of traditional manual cleaning methods and existing cleaning robots, ensuring optimal energy generation and extending the lifespan of solar installations.
