The sunlight slowly moved to the Tropic of Capricorn, and the winter has quietly arrived. Lithium battery solar street lights are a type of outdoor lighting products that use solar power to generate electricity. It is inevitable that many people worry that solar street lights will be affected on weekdays. So, how to ensure sufficient lighting time for solar street lamps in winter?
1. Lighting Standard
In fact, compared with summer, the compressive strength and duration of light are reduced, and the sun still exists. In summer, because the light is easy to use, two or three hours can be full of electricity. In winter, the battery duration has been increased correspondingly due to the light standard, but if the lighting duration is sufficient, the battery can also be fully charged.
2. Underground battery
At present, most of the solar street lights are all lithium batteries, which are resistant to low temperatures and can be integrated into ultra-low temperatures of minus 40 degrees Celsius. The low temperature resistance of the battery is far inferior to that of the lithium battery, and the road surface is cold. Some underground solar street lights must pay attention to winter safety protection. If the battery is buried shallow, it is likely to cause the rechargeable battery to be cold, so the battery must be buried at least one meter deep.
Third, the solar panel snowfall
It is impossible to prevent snow drifts in winter, small cold or sleet snow will not easily affect all normal applications of solar panels, but it is necessary to take measures in case of snow and heavy snowstorms, because the snow cover the solar photovoltaic panels will produce dark areas , Resulting in uneven conversion of solar photovoltaic panels, affecting the high efficiency of power generation. Therefore, it is one of the ways to ensure the sufficient lighting time of lithium battery solar street lights in winter to do a good job of snow removal.
In summary, under normal winter weather conditions, solar street lights will not be affected much, and all normal applications are fine.
