A brief analysis of solar light factories: What are the advantages of solar street lights than conventional street lights?

Since the advent of solar street lights, they will inevitably be compared with conventional street lights. It is said that solar street lights are better than conventional street lights, but how are solar street lights better than conventional street lights? If nothing else, just one place is enough to see. Let us analyze it for everyone below. Due to the long low-voltage transmission lines of conventional street lights, not only the street lights consume power, but also the power consumption on the transmission line. The conventional street lights must be powered by buried cables. A power supply line must be built on a highway more than three kilometers away from the power source. With the extension of kilometers, a booster system is also needed. Therefore, most of the suburban roads and expressways far away from the power point are not equipped with street lights, which actually brings many safety problems to road traffic, and also brings inconvenience to people's night travel. Unlike it, solar street lights formally avoid these drawbacks. Since sunlight is used as the energy source, buried cables are naturally not used, and the grid is not used for power supply. I don't know how much engineering and costs are saved, or the simple installation will not hinder road traffic problems. It can be seen that solar street lights are better than conventional street lights. Fortunately, they don't require so much engineering, do not consume energy, and can be used anywhere.
