Solar street lights play an important role in our modern lives. They have a positive impact on the environment and enhance resource utilization. Solar street lights not only help avoid electricity wastage but also effectively utilize new power. However, after prolonged operation, solar street lights may encounter some issues, as outlined below:
Common problems that arise with solar street lights after prolonged use:
1. Flickering lights
Some solar street lights may experience persistent flickering or unstable brightness. Aside from inferior quality solar street lights, a significant portion of these issues is caused by poor connections. If you encounter such situations, the first step is to replace the light source. If the flickering persists after replacing the light source, it indicates that the light source is not the issue, and you should check the wiring, as poor connection in the wiring could be the cause.
2. Short illumination time on rainy days
Generally, solar street lights can last for 3-4 days or even longer during rainy days. However, some may fail to light up or only last for a day or two. There are two main reasons for this. The first is that the solar battery may not be fully charged. If the battery is undercharged, it is due to inadequate solar charging. Check the recent weather conditions to ensure that it has enough charging time of 5-7 hours daily. If the charging time has been short, the battery itself is likely fine and can continue to be used. The second reason could be an issue with the battery itself. If the charging time is sufficient and the battery still does not charge fully, consider that the battery may be aging. If aging occurs, it should be replaced promptly to ensure the solar street light operates normally. The normal lifespan of a battery is about 4-5 years.
3. Solar street light stops working
When a solar street light stops working, the first thing to check is whether the controller is damaged, as this situation is often due to a malfunctioning solar controller. If damage is found, it should be repaired promptly. Additionally, check if the wiring has aged.
4. Dirty or damaged solar panels
After prolonged use, solar panels are prone to dirt and damage. If leaves, dust, or bird droppings are found on the panels, they should be cleaned promptly to avoid affecting the panels’ ability to absorb light. If the solar panel has missing parts that affect charging, it should be replaced in a timely manner. Moreover, during installation, try to avoid obstructing the solar panels, as it can affect their charging efficiency.
This concludes the discussion on common problems with solar street lights after prolonged use. Solar street lights not only effectively utilize their functional features but also have a better impact on the environment and energy conservation. More importantly, they have a long lifespan and can operate normally in various site environments.
