Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a fully automatic photovoltaic power supply hanging photovoltaic panel cleaning device. Background Technology

[0002] Against the backdrop of global energy transition and sustainable development, solar energy, as a clean and renewable energy source, has seen its development and utilization scale continuously expand. Photovoltaic power generation, as one of the main methods of solar energy utilization, relies heavily on photovoltaic panels as its core component, whose power generation efficiency directly affects the performance and economic benefits of the entire photovoltaic system. However, during actual operation, photovoltaic panels are inevitably affected by various environmental factors, leading to the accumulation of dust, sand, bird droppings, leaves, and other contaminants on their surfaces. These contaminants significantly reduce the photovoltaic panels' ability to absorb and convert sunlight, thus affecting power generation efficiency. Therefore, regular cleaning is necessary. With the increasing cost of labor each year, replacing manual labor with cleaning machines for photovoltaic panel cleaning has become a development trend. Autonomous mobile cleaning machines are widely used due to their flexibility and efficiency. Fully automatic photovoltaic-powered hanging photovoltaic panel cleaning devices are mainly designed for large-scale photovoltaic fields, enabling automated cleaning of rows of installed photovoltaic panels.
