The anti-theft issue of solar street lamps cannot be ignored. Solar street lamps are generally composed of solar panels, lamp holders and light sources, lamp poles, batteries, and controllers. These accessories are mostly connected through hardware structural components, so they are easy to remove. Due to the strong versatility and high value of solar panels, lamp holders, and batteries, they are easily targeted for theft. In addition, some solar street lights are installed in rural areas, located on remote road sections and left unattended, which inevitably becomes the target of some illegal elements. Among them, solar panels and batteries are easily stolen, and there are also some places where only one lamp pole is left. So, the anti-theft issue of solar street lights must be taken seriously.
