Solar panels (PV modules) are a popular alternative energy source. The outer layer of toughened glass protects the solar cells from heat and weathering. The cleanliness of the surface has a significant impact on energy conversion, as dirt and dust can hinder the absorption of solar radiation. This study aimed to design, develop and analyse a solar panel cleaner using innovative wet and dry cleaning technologies. The design process resulted in detailed equipment specifications. Key components were assembled and tested for functionality. The dry cleaning system uses a rotating brush (three-cycle mops) connected to a DC motor. The wet cleaning system uses a nozzle at the end of the tool to deliver pressurised water from a DC pump connected to a water tank. The prototype was field-tested to assess the effectiveness of wet and dry cleaning methods on solar panels. The solar panel cleaner can be used for both wet and dry cleaning. Future improvements may result in an aesthetically pleasing, durable, effective and efficient solar panel cleaner.
