Why solar street lights are not working?


Solar street lights use solar energy as energy. During use, due to the great influence of natural factors on outdoor work, it is inevitable that some failures will occur that affect our use. Repair the cause of the failure, so as not to affect our use. So what are the reasons why the solar street lights do not turn on?

1. The line is ageing or the line is disconnected

In this case, the wiring should be carefully checked. The solar street light will not light up or flash when it is connected normally, it is likely that the line is loose or disconnected, we can reconnect the wire or replace the wire.


2. The battery does not work properly, the voltage is too low

There is a problem with the battery. For example, the positive and negative poles are reversed, the contact is poor, the service life is expired, and the battery is damaged, which causes the solar street light to not work and the voltage is relatively low.

At the same time, the battery configuration is too small to meet the set requirements for the number of cloudy and rainy days. As the battery ages, the lights will not turn on at night.


3. The positive and negative poles of the solar panel are reversed

After the solar street light system is installed, it will only light up once, and when the battery is used up, the solar street light will never light up again.


4. Damaged solar panels

The solar panel is not connected to any load in the sun, and does not connect to the controller, directly pulls out the wire of the solar panel, and connects it to a multimeter to test its voltage.


5. The LED light source is damaged

This is a relatively common reason. The LED light source is damaged due to natural or man-made reasons, resulting in the LED street light system not working, sometimes on and off, flickering and so on. You can first check whether the LED lamp beads have black spots. If there are black spots, you need to replace the LED light source.


6. The controller is damaged

It may be that the controller of the solar street light is damaged, after wind, rain, lightning strikes or other reasons, the controller cannot run normally. If it is because the controller is damaged, the original controller should be removed, and then the controller of the same model should be selected and debugged.


7. The controller is connected incorrectly

The lighting of solar street lights is generally controlled by the controller. If the solar street lights are sometimes on or off, and the lighting time is relatively short, are on during the day, not on at night, or always-on, which is most likely to be because of a problem with the controller, the solution is to reconnect the controller. If there is no indicator light on the solar street light controller, the surface controller is faulty, and the corresponding controller should be repurchased.

In fact, in addition to the above factors that cause the solar street lights not to light up at night, there are also other reasons, like because customers are looking for cheap prices when purchasing, some manufacturers have set the power configuration of the solar panels to be too small, resulting in dissatisfaction with the battery charging. After the rainy weather, the illumination of the lights will gradually dim, and it will hardly light up in less than a year, and there will be cases where the lights do not light up at night.

 

In short, for the problem that the solar street light doesn’t work, we must comprehensively consider it, check and repair it step by step, so as to ensure the brightness of the solar street lights.
