Generally, there are two ways for the solar street light – solar street light with motion sensor and solar street light with timer. The controller of solar street light does not have a built-in clock, and it generally does not operate according to the clock. The turn-on time is generally to trigger the turn-on circuit by monitoring the current of the solar panel. As we know, solar panel will generate electricity current when the lights on the solar panel. So we just need to monitoring the start current and turn on/off the solar street light. Mostly the current value is set to 5mA, it means when the current that solar panel generated is less than 5mA, it will turn on the solar street light automatically. And with the aging of the solar panel, the current value can be adjusted accordingly.

The adjustment ways of each controller of solar street light is different. Some through infrared ray, and some are working through networking. The best solution is to let the supplier complete the operation for you.
The turn on/off setting of solar led street lights is very intelligent. It is controlled by the intensity of sunlight, usually at 19-20 o’clock in summer, and at 17-18 o’clock in winter. There are generally 5 setting methods for solar led street lights.
Light Control Setting
Light-controlled on/off means that it is only controlled by sun light, and it will automatically sense the intensity of light to control the light on and off. After installation, there is no need to adjust the light on and off time according to the season. This kind of light-controlled solar street lamp has a wide application range, and its cost is slightly higher than other control methods.Time Setting
Time-controlled on/off is a common control method for solar street lights, which is to set the lighting time through the controller in advance. The street light will be automatically turned on at night, and automatically turned off or dimmed after the specified time. This control method is relatively reasonable, which can not only control the cost of solar street lights, but also extend the service life of solar street lights.Motion sensor control setting
Solar street light with motion sensor mean the lamp integrated a body motion sensor. When the human body movement is detected, the solar street light will automatically adjust to full power output. When no one is moving, the solar street light will be adjusted to dim or turn off. This can avoid unnecessary waste of power, save battery energy, and extend the lighting time.Setting by Remote controller
The solar street lights that can be controlled by the remote control, they are generally used in household solar street lights. In your house, people hope that the solar street lights can be controlled by switches like the city circuit lights. Therefore, the solar street light manufacturers have developed a special energy for household solar street lights. A household solar street light that controls the lights on and off at any time with a controller.Combination setting of light control + time control + motion sensor control
There are three basic methods for different combinations, such as light control lighting + time control dimming, light control lighting + time control dimming and other combinations. This can save battery power and reduce the configuration cost. This is currently the most used control method.
The above are several control setting modes of solar street lights. This control is mainly done by solar controllers. The solar controllers have many basic functions, such as overload protection, short circuit protection, lightning protection, overcharge and over-discharge protection, and so on. The combination of its various control methods enhances the flexibility of the solar street light system. The solar controller is connected to the solar panel, battery, and light source, and controls them to operate efficiently. The controller is a very important part of the street light photovoltaic system, which enables the entire solar system to operate efficiently and safely.
