What if the solar street light does not turn on?

Nowadays, due to the general trend of environmental protection, more and more places are using solar street lights, but after a long time, the solar street lights will not turn on, so what should we do? If the solar street lamp fails to light up, it must be dealt with in time to prevent other normal components from being damaged and lost due to the damage of related components.
Identifying the cause of the failure can be done from the following aspects:

First of all, check whether the location of the street light installation is blocked
Although solar street lights can absorb light and energy without the sun during the day, if the light of the solar street lights is poor, it will also cause the solar cells to be unable to absorb and store electricity. Therefore, it is necessary to check the light on the site of the solar street light installation. normal.
Second, check whether the LED light source is in a short-circuit state;
Most of the solar street lights now use LEDs as the light source. When some LED street lights are not on, in addition to checking the quality of the LEDs, it is also necessary to check the problem of unstable oxidation at the wiring. Sometimes it is often because of the wiring. Except for the problem;
Third, check whether the solar street light controller is working; (suitable for solar street lights with buried batteries)
The controller that is more likely to have problems in solar street lights is the controller. If the quality of the controller is not good enough, it will affect the life of the entire system. It is more intuitive to view the controller. Conventionally, there are indicators on the controller. If the battery light does not light up, the battery is serious If there is no power supply or the controller is damaged, the positive and negative poles of the wiring can be disconnected. If there is a fire and the spark is very loud, it proves that the battery has electricity. The problem is the controller, then you can just replace a controller. The basic cost is less than 100 yuan. If the battery fails to respond, you need to replace the battery. It needs to be noted that sometimes the battery cannot be caused by the controller problem. The battery runs out of charge in the morning.
