How to maintain solar street lights in winter

Winter is the solar street "peak incidence", there are many solar lights are quality problems in winter, a common problem is the lack of lighting at night time, for example, could have been light six hours a day in winter only bright thirty-four hours or direct light It will not light up. The reason for this phenomenon is mainly caused by battery feeding. So what is the reason for this?

The reason is that the configuration of the solar street light system is low. The light in winter is not as good as in other seasons. The solar panel is not generating enough electricity. At the same time, the discharge of the battery in winter is only 70% of that in summer. Therefore, the winter point is not enough. The battery's power is only bright enough for two or three hours every day.

1. The weather is cold in winter, and the battery will be "frozen" due to freezing, resulting in insufficient discharge. Usually in cold areas, the battery should be buried at least 1 meter deep, and 20 cm of sand should be laid on the bottom to facilitate the dissipation of accumulated water, so as to prolong the life of the battery. The lithium battery needs to be insulated with thermal insulation cotton.

2. Insufficient solar panel power generation, enough electricity generated every day to fill the battery. In winter, the sun will move south and the sun's altitude will decrease, resulting in insufficient light. In some places, the solar panel is blocked by tall objects such as houses and trees or partly blocked by light, resulting in insufficient power generation.

3. The solar panel has not been cleaned for a long time, and too much dust affects the power generation. In some places, it often snows, and the snow covered solar panels cause insufficient power generation. Therefore, it is necessary to clean up the dust and snow on the solar panels frequently, preferably every two months.

4. Reach a certain service life. If the battery has charge and discharge times, the amount of electricity will gradually decrease with the increase in the number of uses. Therefore, it is normal for solar street lamps to be used for more than 3 years and the lighting time will gradually decrease. The problem can be solved by replacing the energy storage battery.
