Solar street lights use solar energy as the power supply to provide road lighting at night. The light-post and battery are design into an integral part with wind resistance and intelligent charging and discharging mode. The investment cost of solar street lights in parks is also relatively small. Once users make a one-off investment, they can be able to use the solar street light for a quite long period.
