Solar street lamps are suitable for areas with a wide range of elevations. Solar street lamps have certain requirements for the installation of altitude, but with the improvement of technology, the altitude requirements range is wider, as long as the altitude is less than 5,000 meters can be installed and used. Generally, it is not recommended to use solar street lamps in areas above 5,000 meters above sea level, but there is no requirement below 5,000 meters above sea level, which can be basically applied to users in ordinary areas.
