Will solar street lights be affected in winter?

Solar street lights are normally unaffected in winter. However, it may be affected by snow. Once the solar panels are covered with snow, the solar lights do not have enough heat to convert into electricity for lighting. Therefore, in order to be able to use solar street lights in winter as usual, it is best to be able to manually or mechanically clean up when there is snow on the panels. In addition, local climatic conditions should be fully considered when installing solar street lights. In most areas of northern China, if there is light snow or sleet climate, solar street lights can be used normally. If there is extreme snowstorm climate, the snow on the panels can also be slightly sorted out to prevent concealing solar panels from forming shadow areas and forming uneven transformation of solar panels. Therefore, when installing solar street lights, we should think about the different climate environment around the country, and the area with snow all the year round should be carefully considered.

1. In the winter battery buried too shallow, cold weather in winter, the battery will be frozen “frostbite”, resulting in insufficient discharge, usually in cold areas, the battery should be buried to at least 1 meter deep, 20 cm of sand at the bottom, to facilitate water dissipation, so as to prolong the life of the battery.

2. Solar panels have not been cleaned for a long time. Too much dust affects power generation.

3. When the street light reaches a certain service life, the number of charge and discharge times of the battery will gradually decrease with the increase of the number of use. Therefore, the lighting time of the solar street light used for more than 3 years will gradually decrease, which is a normal phenomenon.

4. Prevent icing: in the selection of solar panels to choose a good process, less joint and less welding products, solar panels to design simple and smooth, and waterproof, so there will be no icing. In cold area to prevent freezing solar street lights, often there will be rain and snow weather cold region is known to all, this kind of weather is easy to let the street light on a layer of ice, because the solar street light is rely on solar panel to collect solar energy to generate power, if the panels were frozen leads to solar street light can’t normal use.
