Yufai: How to maintain solar street lights in winter

Winter is a cold day of the year, and it is also a season with little sunshine. Solar powered street lamp is a solid-state cold light source, which has the characteristics of environmental protection, pollution-free, low power consumption, high luminous efficiency, and long life. Therefore, street lamps will become the choice for energy-saving transformation of road lighting. Many street lamps have quality problems in winter. . A common problem is that there is not enough light time at night. For example, in the past 6 hours a day in the morning, but only 3-4 hours in winter. The main reason for this phenomenon is battery supply. As a Solar street light supplier, Yuhui Aurora will explain to you one by one next?

And in winter, the sun is not as good as summer, solar panels are not enough to generate electricity, the battery discharge in winter is only 60% of summer, the temperature in winter is not enough, the battery power is only 2 hours or 3 hours a day.

1. The battery is buried too shallow, the weather is cold in winter, the battery is "frozen" due to freezing, and the discharge is insufficient. Generally 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 water and extend the service life of the battery.

2. Solar panels cannot generate enough power, and the power generated every day is not enough to fill the battery. In winter, the sun moves to the south and the sun's altitude angle decreases, resulting in insufficient light. In some places, solar panels are blocked by high objects such as houses and trees, or partially blocked by light, resulting in insufficient power generation.

3. Solar powered street lamp battery panels have not been cleaned for a long time, and there is too much dust, which affects power generation. In some places, due to frequent snowfall, the snow-covered solar panels cause insufficient power generation. Therefore, clean up the dust and snow on the solar panels every two months.
