Solar street lamp plays an important role in our modern life. It has a good maintenance effect on the environment, and has a better promotion effect on the use of resources. Solar street lamps can not only avoid power waste, but also effectively use new power together. However, solar street lamps sometimes have some problems after a long time of work, as follows:
Problems that are easy to occur when solar street lamps work for a long time:
1. The lights are flashing
Some solar street lamps may flicker or have unstable brightness. Except for those low-quality solar street lamps, most of them are caused by poor contact. In case of the above situations, the light source must be replaced first. If the light source is replaced and the situation still exists, the light source problem can be ruled out. At this time, the circuit can be checked, which is probably caused by poor contact of the circuit.
2. Short luminous time in rainy days
Generally, solar street lamps can last 3-4 days or longer in rainy days, but some solar street lamps will not light or can only last for one or two days in rainy days. There are two main reasons for this. The first case is that the solar battery is not fully charged. If the battery is not fully charged, it is the problem of solar charging. First, learn about the recent weather conditions and whether it can guarantee 5-7 hours of charging time every day. If the daily charging time is short, the battery itself has no problems and can be used safely. The second reason is the battery itself. If the charging time is enough and the battery is still not fully charged, it is necessary to consider whether the battery is aging. If aging occurs, it should be replaced in time to avoid affecting the normal use of solar street lamps. The service life of the battery under normal operation is 4-5 years.
3. Solar street lamp stops working
When the solar street lamp stops working, first check whether the controller is damaged, because this situation is mostly caused by the damage of the solar controller. If it is found, repair it in time. In addition, check whether it is caused by aging of the circuit.
4.Dirt and missing corner of solar panel
If the solar street lamp is used for a long time, the battery panel will inevitably be dirty and missing. If there are fallen leaves, dust and bird droppings on the panel, they should be cleaned in time to avoid affecting the solar panel’s absorption of light energy. The solar street lamp panel shall be replaced in a timely manner in case of missing corner, which affects the charging of the panel. In addition, try not to cover the solar panel during installation to affect its charging effect.
The above problems about solar street lamps that are easy to occur after a long time of work are shared here. Solar street lamps can not only give full play to the functional characteristics of use, but also have better environmental and power saving effects. More importantly, it has a long service life and can work normally in various on-site environments.
