It depends. Both LED street lights and solar street lights have their own advantages and suitable situations. For example, if you are planning to set street lights for some main roads or highways, LED street lights will be better. For these roads, you will need bright and constant light, and solar street lights can be dim or won’t light up on continuous rainy days. But for lighting up village roads in some remote areas, because sometimes electricity is not available, solar lights are the best choice. And solar lights are also suitable because these rural roads have a relatively low requirement for street lighting.
I saw there were ground wires and a rod at the base of the parking lot light pole. But if there are ground wires in the parking lot circuits, do we still need the grounding in the base?
