Solar street lights rely on solar panels to absorb sunlight, converting the energy into electricity stored in battery packs. When there is a demand for light, the batteries continuously release electrical energy. However, in northern regions, the cold winter winds and limited sunlight may affect the operation of solar street lights. Below, we provide a detailed introduction to this topic.
Firstly, it is a fact that winter sunlight is not as strong as summer sunlight. Generally, if it is sunny most of the time in winter, even if the sunlight is not very intense, solar street lights will not be significantly impacted. However, if there is rain or snow, problems may arise. On one hand, solar street lights cannot absorb sunlight during such conditions, leading to insufficient power supply at night. On the other hand, if it snows, the solar panels can become covered by a thick layer of snow, blocking their ability to absorb sunlight. In either case, there will be some effects on solar street lights.
Especially in Northeast China, where it frequently snows in winter, it is essential to regularly clear snow from the solar panels. During this time, the brightness of the solar street lights is noticeably less than in summer, but if there are no significant issues, basic illumination is still achievable.
In winter, we also need to pay close attention to the condition of the batteries. For example, in extremely snowy weather, batteries that are buried too shallow underground or installed directly behind the solar panels can easily freeze. However, not all batteries have this issue; some are designed to operate in extremely cold weather, even in conditions as low as -40°C.
When purchasing solar street lights, it is crucial to buy high-quality products from reliable manufacturers, taking weather conditions into full consideration. In regions like Northeast China, where it often rains in winter, these factors must be accounted for when selecting batteries.
The above information regarding the impact of cold winters on the operation of solar street lights is shared here. In summary, when installing solar street lights, it is important to consider the varying climate conditions in different regions. In areas with year-round snow, careful consideration is necessary. Moreover, it is essential to choose brands and manufacturers known for their reliability and quality when installing solar street lights.
