The solar industry professional article winter is the peak season of solar street lights. There are many solar street lights that have quality problems in winter. The common problem is that there is not enough time for lighting at night. For example, it is 5 hours per day and only two or three in winter. The light is off in an hour. The reason for this phenomenon is mainly caused by battery feeding. So what is the reason?
we produce rare earth magnesium ferrosilicon 5000mt/year,we export the material to japan,india,Europe ect.

Solar street lights are low in configuration. Winter lighting is not as good as summer, solar panels are not generating enough electricity, and the battery discharge in winter is only 70% of the summer, so the winter is not enough. The battery power is only enough for two or three hours a day.
The battery is buried too shallow, 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 is laid at the bottom to facilitate the dissipation of water, so as to extend the life of the battery.
Solar panels are not generating enough electricity, and the electricity generated every day is not enough to fill the battery. The winter sun moves south, and the sun's elevation angle decreases, causing insufficient light. In some cases, solar panels are blocked by high objects such as trees or partially blocked by light, resulting in insufficient power generation.
Solar panels have not been cleaned for a long time, and there is too much dust, which affects power generation. Some places are because of the frequent snow, snow covered solar panels cause insufficient power generation. Therefore, it is necessary to clean the dust and snow of the solar panels frequently, and it is best to clean them once in two months.
Achieve a certain service life. When the battery has a number of charge and discharge times, the amount of electricity will gradually decrease as the number of uses increases. Therefore, it is normal for the solar street lamp to be gradually reduced in use for more than three years. Replacing the energy storage battery will solve the problem.
Our company's solar street lights are calculated according to the worst weather conditions in the winter of use. As long as you strictly follow the installation requirements of our company, there will be no shortage of lights during the warranty period. Please feel free to use them.
