We know that road lighting is an important part of urban illumination. In the past, we used traditional streetlights, which are now gradually being phased out. Solar streetlights have become a popular product. Solar streetlights are powered by crystalline silicon solar cells, store electrical energy in maintenance-free valve-regulated sealed batteries (gel batteries), use ultra-bright LED fixtures as light sources, and are controlled by intelligent charge and discharge controllers to replace traditional utility-powered lighting. What problems might solar streetlights encounter during use? Below are several common issues compiled for your reference.
The first situation: The light of the solar streetlight flickers and has unstable brightness.
If this phenomenon occurs, the first step is to determine if it is an issue with the light head. Try replacing the light head. If flickering persists even after changing the light head, it can be concluded that the problem does not lie there. At this point, check the wiring, as poor connections in the wiring can lead to this situation.
The second situation: The solar streetlight can only last one to two days on cloudy or rainy days.
There are mainly two reasons for this phenomenon:
1. The solar battery is not fully charged. If the solar battery is not fully charged, it could be due to insufficient solar power input. First, observe the recent weather conditions to see if it has been able to charge for around 5 to 7 hours daily. If there has been frequent cloudy or rainy weather recently, resulting in only 2 to 3 hours of charging, this is normal. The solar streetlight can return to normal operation when the weather improves.
2. Check if there is any aging of the solar battery. Under normal operating conditions, the lifespan of the battery is 8 to 10 years.
The third situation: The solar streetlight has stopped working and is not lighting up.
First, check whether the intelligent control system is functioning properly. Generally, issues like this are often related to the intelligent control system. If there is a problem with the intelligent control system, timely repairs or replacements are necessary.
The fourth situation: The solar panel is obstructed by external objects.
When installing solar streetlights, make sure that the solar panels are not obstructed by any objects to ensure they can properly absorb sunlight for charging. Periodic maintenance and cleaning of solar streetlights should be carried out, especially in dust-prone areas, where cleaning should be done once a year. In less dusty areas, the frequency can be adjusted to once every three years to ensure the proper functioning of the solar panel’s charging process.
The above are the common problems encountered with solar streetlights. Overall, by understanding the potential issues that may arise with solar streetlights, we can resolve any problems quickly when they occur during use.
