How to clean up and maintain our solar street lights in winter

Winter is the "peak period" of solar street lights. Many solar street lights have quality problems in winter. The common problem is that the lights are not lit at night. For example, the lights are turned on for 5 hours a day, and they are only turned off for two or three hours in winter. . The reason for this phenomenon is mainly caused by the battery feed. So what is the reason?



Low configuration of solar street lights. The sunlight in winter is not as good as that in summer, and the solar panel is insufficient to generate electricity. At the same time, the battery discharge in winter is only 70% of that in summer, so it is not enough in winter.


1. The battery is buried too shallow, the weather is cold in winter, the battery will be "frostbite" when frozen, resulting in insufficient discharge. Usually in cold areas, the battery should be buried to a depth of at least 1 meter, and 20 cm of sand should be laid at the bottom to facilitate the dissipation of the accumulated water, so as to prolong the battery life.


2. Insufficient power generation from solar panels, the electricity generated every day is not enough to fully charge the battery. In winter, the sun moves south, and the height angle of the sun decreases, resulting in insufficient light. In some places, solar panels are blocked by tall objects such as houses and trees or part of the time due to light, resulting in insufficient power generation.

 

3. The solar panels have not been cleaned for a long time, and there is too much dust, which affects power generation. In some places, it is often snowy, and snow covered solar panels cause insufficient power generation. So always clean up the dust and snow on the solar panels, and clean up once every two months.


4. Reach a certain service life. The battery has a number of charge and discharge times, and the power will gradually decrease with the increase in the number of times of use, so usually the solar street light will gradually reduce the lighting time for more than 3 years, which is normal. Replacing the energy storage battery can solve the problem.


In recent years, with the country's strong support for the environmental protection industry and the development of solar street light industry,

Lights are becoming more and more popular. How to use solar street lights correctly is very important. Proper installation before use is a

It is also part of the correct maintenance after use. Today, we can summarize it for you

Some common faults and solutions of solar street lights, I hope to help everyone better daily maintenance of solar street lights.


1. The following matters need to be paid attention to in the daily use of solar panels:


(1) Do not let hard or sharp objects hit the solar panel, otherwise the solar panel will be damaged.


(2) The solar panel should be cleaned regularly during use (the time can be a quarter or


Semiannually). Keep the surface of the solar panel clean, otherwise it will affect the conversion efficiency.


(3) Do not allow some things (such as branches, billboards, etc.) to block the surface during use, otherwise it will affect the rotation

Change efficiency.


(4) Problems of orientation and angle during solar installation.


If it has been installed and used normally for a period of time, first check the reaction of the indicator light of the controller;


a. All the indicators are off, it is possible that the battery is over-discharged, and the battery hardware is protected. You can see the indicators the next day.

Status: If the red light is always on and the blue light is blinking, it means that the lamp is charging normally, then the lamp is normal;

If the indicator status is off, you need to contact the manufacturer's engineer for further analysis.


b. The light is normally on for a period of time, but it is found that the light is on for a short time, please observe the surrounding environment, solar panels

With or without cover, the installation angle of the solar panel, whether to adjust the angle of the maximum irradiation area of the road surface, and the most

Whether it has been rainy for several days in a row, if none of the above problems, please use the universal remote control to read the setting parameters

Number, whether it is the normal factory mode setting, the current setting may be too high or the control factory mode may be changed to cause the

The light time is short. If this is the case, please return to the factory default mode.
