Many times, we see that the solar street lamp is not on at the roadside. What happened? In addition to life expiration, the following reasons will also cause solar street lamp does not work.

The solar panel is damaged. If the solar panel is damaged, there will be no electric energy storage in the whole solar street lamp system, resulting in no energy supply for the solar street lamp. At night, the solar street lamp does not light because there is no electric energy supply.

The damage to the solar street lamp controller will also cause the solar street lamp not to light up. If the parameter setting of the solar street lamp controller is wrong, the solar street lamp will not light up normally.

If the solar street lamp controller is damaged, the solar panel will not be able to store the generated electric energy in the lithium battery, Nor can the electric energy stored in the lithium battery be supplied to the LED light source of the solar street lamp, resulting in the LED light source of the solar street lamp not working normally.

If there is a problem with the lithium battery of the solar street lamp, the whole solar street lamp system will have no electric energy to store, and can not normally provide electric energy to the LED light source at night, and can not work normally at night.

On the whole, the service life of solar street lamps is very long. The service life of the LED light source is 3-5 years, the service life of the controller and lithium battery is 5-8 years, and the service life of the solar panel and street lamp pole is more than 20 years.

Therefore, if the newly installed solar street lamps or solar street lamps with short service life do not turn on, they are generally out of order. It’s good to maintain them, Regular inspection and maintenance of solar street lamps can effectively prolong the service life of solar street lamps.
