Background technique

Solar energy is the most important renewable energy source, it does not produce any pollution and is free to use. In the latter half of the 20th century, many countries began to attach importance to the development and utilization of solar energy. In the 21st century, from solar water heaters to solar power generation, more and more solar energy utilization technologies are applied to people's production and life. Solar energy has become an indispensable energy source for social development. In recent years, street lamps powered by solar energy have appeared in many cities. The use of solar street lamps has greatly relieved the pressure on urban electricity consumption, and has been recognized by the society. It is likely to replace the original street lamp system. However, due to the increasing urban industrialization and air pollution, the problem of dust accumulation on the photovoltaic panels of solar street lamps is serious, which greatly affects the power generation efficiency of photovoltaic panels.

ZL01270896.8 discloses a solar elevated street lamp device. In order to avoid the generation of dust accumulation on the photovoltaic panel, a transparent protective cover is set above the photovoltaic panel. Dust exists on the protective cover instead, which hinders the photovoltaic panel from lighting and also affects the power generation efficiency of the photovoltaic panel.

Therefore, the most effective and direct method is to directly clean the photovoltaic panels. The cleaning of photovoltaic panels of solar street lamps is usually carried out by the high-pressure water column of the cleaning vehicle.
