Why Do My Solar Lights Come on During the Day?
Oct 26, 2024
How to reduce carbon emissions and promote sustainable development has become a consensus of the international community. As a clean and renewable green energy source, solar energy is being applied to every corner of our lives. As an innovative application of solar technology in lighting systems, solar led street lights have gradually become the first choice for urban lighting scheme reform. Solar street lights have shown extraordinary effects in reducing carbon emissions and promoting environmental protection. A self-sufficient energy supply has freed solar street lights from dependence on traditional power grids, reduced the use of fossil fuels, and achieved green energy savings.
However, solar street lights will also have some faults during operation. For example, we recently received feedback from some customers that their solar led street lights would light up during the day. I don’t know if you have encountered the same problem. In the following article, let’s analyze why solar street lights light up during the day!
Normally operated solar street lights should be charged during the day and discharged at night. If your solar powered street light is lit during the day, there must be a problem with one of the links. Once found, it must be dealt with in time to avoid affecting the normal operation and service life of the solar powered outdoor street lights. This article analyzes the reasons and treatment measures for solar powered streetlights to light up during the day. If the above methods cannot solve your problem, please contact your solar street light supplier in time.

Working principle of solar street lights
To understand why solar street lights light up during the day, we must first know the working principle of solar street lights. The basic principle of solar street lights is to use solar panels to convert the light energy collected during the day into electrical energy and store it in lithium batteries. When the light becomes weak at night, the solar panel supplies the stored electrical energy to light up the street lights. The core component of solar led street lights is the intelligent charge and discharge controller, which is responsible for controlling the charging of the battery and the turning on and off of the street lights.Five reasons why your solar street lights come on during the day
1. Check if there is any shadow at the installation location
Solar powered outdoor street lights need sufficient sunlight to charge them, but if the location where your street lights are installed is full of shadows, the light sensor will mistakenly think it is night and light up the street lights. At this time, you need to check whether there are tall obstructions around the installation location of the street light. If it is a tree or other plant, you can trim it regularly so that the solar street light panels can fully receive sunlight. If it is some buildings, you can choose to adjust the angle and position of the solar panel to allow it to receive as much sunlight as possible. If the above two methods cannot solve the problem, you need to consider moving the location of the solar powered outdoor street lights.2. Check the light sensor.
In your solar street light, there is usually a built-in light sensor, which can detect changes in light and control the switch of the solar street light. However, if dust or debris accumulates on the light sensor, it will affect the normal operation of the light sensor and it will not be able to normally identify changes in light, causing the solar street light to light up during the day. In addition, if the solar street light has suffered physical damage, such as impact, the light sensor may be damaged, which will also affect its normal use. At this time, you can deal with it according to the actual situation. If there is only dust or debris, you can clean it and use it again. If it is damaged, you need to replace it with a new light sensor.3. Check the solar panel.
If dust and other debris accumulate on the surface of the solar panel, it will not only hinder direct sunlight and charging but also block the sensor, making it mistakenly think it is nighttime, so it lights up the solar powered outdoor street lights. Therefore, you need to check and clean the solar panel regularly, especially in the season with more wind and rain. Cleaning the solar panel is actually very simple. You only need to use a mild detergent to moisten the soft cloth and gently wipe the solar panel. If there is dirt, you can carefully remove it with a soft toothbrush. After scrubbing, rinse it with clean water.4. Check for water seepage
If you find that your solar powered streetlights suddenly lights up during the day, you can recall whether it has rained recently in your area or whether you have cleaned the solar street light recently, because water or moisture can also affect the normal operation of the light sensor. Although solar powered outdoor street lights are generally waterproof, moisture may also enter the interior of the street light under high humidity and continuous heavy rain weather conditions. At this time, you can disassemble the solar street light and wipe it dry, and then assemble it after confirming that it is dry.5. Check the battery
If all the above reasons have been checked, you need to check whether your battery has degraded or damaged. Check whether the battery power is exhausted and whether the battery is undervoltage. The battery of the solar powered LED street light may be undervoltage after long-term use. After long-term use, when the battery voltage continues to drop to a certain threshold, in order to protect the battery, the controller of the solar street light will stop discharging and the street light will go out. However, when the battery voltage gradually recovers to a certain level during the day, the controller may mistakenly think that night has come and then light up the solar street light. If you find that the battery of the solar street light is aging or undercharged when checking it, please replace the battery in time.Four ways to avoid the solar street light come on during the day
1. Try to avoid installing it in dusty areas.
Because the accumulated dust will not only affect the direct sunlight but also cause the light sensor to malfunction and fail to work properly. If it cannot be avoided, please increase the cleaning frequency to keep the solar powered LED street lights clean.2. Regularly trim the obstructions around the solar street light.
If the solar street light is inevitably installed in a location blocked by trees, please trim it regularly to prevent the lush branches and leaves from blocking the panels from fully receiving sunlight and affecting the normal operation of the solar street light.3. Check the various components of the solar street light.
Regularly check whether the various components of the solar powered streetlights are damaged and whether the settings are reasonable. The solar street light is an independent lighting system. Whether each component is normal will affect its normal operation.4. Check the intelligent controller and sensor of the solar powered LED street lights.
The intelligent controller is mainly responsible for the charge and discharge control, intelligent adjustment, and protection functions of the solar street light system, while the sensor is mainly used to monitor the temperature and provide feedback signals to the controller.Normally operated solar street lights should be charged during the day and discharged at night. If your solar powered street light is lit during the day, there must be a problem with one of the links. Once found, it must be dealt with in time to avoid affecting the normal operation and service life of the solar powered outdoor street lights.
