Abstract: As climate change and global warming threaten the future of our planet, it is becoming increasingly crucial to find sustainable ways to fulfill our energy requirements. One of the most efficient ways of moving towards renewable and non-polluting energy sources is to generate electricity using solar panels to harness the sun’s energy. Since they have no moving parts, solar panels are one of the most cost-effective and low-maintenance ways of generating. Despite all their benefits, the efficiency of solar panels can plummet if dust, dirt, and grime are allowed to accumulate. If maximum efficiency in power generation is to be maintained, solar panels need to be cleaned timely. However, manually cleaning solar panels is hazardous and time-consuming. This Solar Panel Cleaning Robot aims to maintain the efficiency of solar power production by making sure the Solar panels are kept clean without putting humans at risk. This robot comes equipped with a roller brush and a water sprayer to clean all dirt and grime from the surface of the panels. The sprayer gets its supply of water through an on-board tank. The rubber caterpillar tracks ensure that this robot can adhere to the slick surface of solar panels. This robot operates remotely and wirelessly. Along with large-scale industrial applications such as dedicated solar power plants, this robot can also help boost the efficiency of solar panels in smaller applications such as rooftop solar panels in homes and offices.
