After the solar courtyard lamp has been installed and used normally for a period of time, it will inevitably encounter some situations that suddenly do not turn on. The solar courtyard lamp itself is used for lighting, if it does not turn on, its lighting value will disappear. So when the solar courtyard lamp is not on, we need to find out the reason and solve the problem. Then, what is the reason and treatment method of the solar courtyard lamp is not on? Solar street lamp technicians answer for you:

1、光源損壞

1. Light Source Damage

由于自然或者是人為的原因造成光源損壞，導致太陽能路燈系統不能工作、時亮時不亮、閃爍等情況。

Due to natural or man-made reasons, the light source is damaged, which results in the solar street lamp system can not work, does not turn on when it is on, flickers and so on.

解決方案：檢修光源或更換光源。

Solution: Maintain or replace the light source.

2、太陽能電池板損壞

2. Damage of solar panels

在太陽能電池板沒有任何負載的情況下連接上萬用表測試其電壓，一般系統工作電壓是12v，正常情況下會比12v電壓高，只有電壓高于12V才可以給蓄電池充電，如果低于12V 則無法給蓄電池充電。太陽能路燈系統不能工作或工作時間不夠。

In the case of solar panels without any load connected to a multimeter to test its voltage, the general operating voltage of the system is 12v, normally higher than 12V voltage, only voltage higher than 12V can be charged to the battery, if less than 12V can not be charged to the battery. Solar street lamp system can not work or the working time is insufficient.

解決方案：更換太陽能電池板。

Solution: Replace solar panels.

3、太陽能電池板正負極接反

3. Connection of positive and negative poles of solar panels

太陽能庭院燈系統安裝后只會亮一次，當蓄電池的電用完后太陽能庭院燈就再也不會亮了。

The solar yard lamp system will only turn on once after installation. When the battery is used up, the solar yard lamp will never turn on again.

解決方案：調換太陽能電池板正負極。

Solution: Changing the positive and negative poles of solar panels.

以上就是關于太陽能庭院燈不亮的原因及處理方法就介紹到這，為了保證太陽庭院燈的正常工作，定期的維護檢查是必不可少的。當然一旦出現了故障，只要按照方法解決一定還是會解決好的。

Above is about the reasons and treatment of solar courtyard lamp not on. In order to ensure the normal work of solar courtyard lamp, regular maintenance and inspection is essential. Of course, once a fault occurs, as long as it is solved according to the method, it will be solved.
