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、光源损坏
1. Light Source Damage
由于自然或者是人为的原因造成光源损坏，导致太阳能路灯系统不能工作、时亮时不亮、闪烁等情况。
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.
解决方案：检修光源或更换光源。
Solution: Maintain or replace the light source.
2、太阳能电池板损坏
2. Damage of solar panels
在太阳能电池板没有任何负载的情况下连接上万用表测试其电压，一般系统工作电压是12v，正常情况下会比12v电压高，只有电压高于12V才可以给蓄电池充电，如果低于12V 则无法给蓄电池充电。太阳能路灯系统不能工作或工作时间不够。
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.
解决方案：更换太阳能电池板。
Solution: Replace solar panels.
3、太阳能电池板正负极接反
3. Connection of positive and negative poles of solar panels
太阳能庭院灯系统安装后只会亮一次，当蓄电池的电用完后太阳能庭院灯就再也不会亮了。
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.
解决方案：调换太阳能电池板正负极。
Solution: Changing the positive and negative poles of solar panels.
以上就是关于太阳能庭院灯不亮的原因及处理方法就介绍到这，为了保证太阳庭院灯的正常工作，定期的维护检查是必不可少的。当然一旦出现了故障，只要按照方法解决一定还是会解决好的。
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.
