How To Fix Your Solar Panel Street Light?

Solar panel street lights are very popular outdoor lighting products on the market. Solar panel street lights are installed not only in cities, but also in many rural areas. The use of solar street lights with motion sensors help us alleviate the shortage of power resources, and it is clean and environmentally friendly. Therefore, the country is now issuing policies to support solar powered street lights. The difference between solar panel street lights and traditional street lamps is that they do not need to be connected to the power grid. As long as there is sufficient sunlight to shine on the solar panels, it can be converted into electrical energy and stored in the battery for street lights to illuminate. Although the installation of solar panel street lights is simple, there is basically no need for maintenance later. But it is an outdoor product after all, after long-term exposure to wind and rain, some small problems will inevitably occur. So in this article, we will introduce to you how to solve some conventional small problems in solar street lamps.

1. The whole light is off

One of the common reasons why the whole solar street light does not light up is that the controller in the light pole has entered water, and there is a short circuit. You can check whether there is water in the controller. If water enters, the controller needs to be replaced. If there is no problem with the controller, check the battery and solar panels again. If the battery is charged and discharged normally, the detection voltage is higher than 12V, and the voltage drops within a short time after the load is connected, indicating that the battery is damaged. If water enters the battery, it will also cause a short circuit and voltage instability. If the solar panel is not connected firmly, it usually shows that there is voltage and no current. You can open the cover behind the solar panel and use the voltage and current meter to check the data. If the battery board does not detect current, it indicates that there is a problem with the battery board and needs to be replaced.

2. The lamp bead does not light up

We know that most solar-powered street lamps now use LED lamp beads. Therefore, after a period of use, some lamp beads may not light up. In fact, this is the quality problem of the lamp itself, for example, the welding is not firm, etc., so at this time we can choose to change the lamp, or choose to re-soldering.

3. The lighting time becomes shorter

After using a solar panel street light for a period of time, even if there is enough light, the light-on time may be short. The lighting time is most likely due to a decrease in the storage capacity of the battery, so we need to replace a new battery at this time.

4. The light source flickers

In general, the flicker of the light source is caused by poor line contact, and it may also be caused by the decrease in the storage capacity of the battery. So we need to check whether the line interface is good, and if there is no problem, we need to replace the new storage battery.

There are many reasons for the failure of solar panel street lights, some are caused by the failure to install them in the early stage, and some are caused by the quality of the lamps. So when there is a problem with solar powered street lights, we must solve the problem according to the actual situation. If you encounter complex problems, you still have to consult a professional solar street light manufacturer. If the accessory is damaged and there is no way to repair it, you can ask the manufacturer to send a new accessory.
