Basically, they make use of photocells and motion detectors to automatically toggle the power of the lights. Photocells detect the presence of natural light and then turn on when the natural light goes away. Sometimes, dusk till dawn sensor light bulbs work with timers which allow them to turn the power on and off during specific times in the day.
Charging voltage increases as the light intensity rises, and decreases as light intensity decreases. When the charging voltage determined with a certain value (e.g. below 5v to switch on and above 5v to switch off), the micro-controller in the controller will automatically turn on/off the electronic switch to turn on/off the solar street light.

of an automatic street light control system. The design works efficiently to turn street lamps ON/OFF. The LDR sensor is the only sensor used in this circuit. The lamps will come “ON” a-light system using timer controller is overcome and human intervention is completely eliminated. By this energy con-sumption and cost are drastically reduced.
Conclusion. Light-dependent resistor (LDR) is a cost-effective and efficient way of introducing automation feature in a solar street light. It will turn the light on or off depending upon the level of natural light in the atmosphere, which will also increase the overall power consumption and operation efficiency of the street light.
