[0002] As global awareness of sustainable development and environmental protection increases, solar energy, as a clean, renewable energy source, is increasingly being used in public facilities and household applications. In the field of public lighting, solar street lights have become very popular because they can reduce dependence on traditional fossil fuels.

[0003] However, a typical solar street light includes a fixed solar panel, which means it can only capture sunlight most efficiently during a specific time period (mainly at noon). In addition, fixed solar panels cannot adjust their angles according to the changes in the sun's position, which limits the efficiency of their energy capture. Since the solar panels cannot maintain the optimal angle, their energy conversion efficiency is lower than ideal for most of the day. Another problem is the maintenance and cleaning of solar street lights. Lamps are exposed to the outdoors and are prone to accumulate dust and other impurities, which block light.
