the advantages of solar street lights. solar street lights are independent of the utility grid resulting to lessened operation costs. these means that these are wireless lights and are not connected to your electricity provider. the lights are dependent of the heat energy given off by the sun, storing as much of it throughout the day.
in order to control charging, charge controller is used. intensity of street lights is required to be kept high during the peak hours. as the traffic on the roads tends to decrease slowly in late nights, the intensity can be reduced progressively till morning to save energy. thus, the street lights switch on at the dusk and then switch off at the dawn automatically. the process repeats every day.
