What Should Be Pay Attention To When Using Solar Street Light In Winter
The solar street light that we often see in our daily lives rely on solar panels to absorb sunlight to obtain energy, and convert the obtained energy into electrical energy and store it in a battery. When lighting products need lighting, the battery will continuously release electrical energy. However, the winter in northern my country is cold and windy and the sun is faint, so what should we pay attention to when using solar street light in winter? Now, the editor of Second Sun will give you an introduction.
1. The solar panel receives a certain amount of light energy per unit of time. The photoelectric conversion efficiency of solar panels is different under the same conditions. In winter, the light conditions are not as good as in summer. If you want to fully charge the battery while there is sunshine, it means that the requirements for the photoelectric conversion efficiency of solar panels are higher.
2. The solar panels have not been cleaned for a long time, and too much dust affects power generation. In some places, it is often snowing, and snow covering the solar panels causes insufficient power generation.
3. The battery will be "frostbitten" if it is frozen, resulting in insufficient discharge because the battery is buried too shallowly and the weather is cold in winter. Usually, the battery should be buried to a depth of at least 1m in cold areas and 20 cm of sand is laid on the bottom to facilitate the dissipation of accumulated water. This will extend the life of the battery.
4. Prevent icing:
There will be no icing when choosing good craftsmanship of solar panels with fewer seams and fewer solder joints by the simple designed, smooth and waterproof
It is necessary to prevent the solar road lamp from freezing in cold areas that everyone knows there are often rain and snow in cold areas. Such weather can easily form a layer of ice on street lights because solar street lights rely on solar panels to collect solar energy for power generation. It will cause the solar street light to not work normally if the battery panel is frozen.
5. The sunshine is not as good as in other seasons in winter. The solar panels are not generating enough power and the battery discharge rate in winter is only 70% of that in summer and the battery's power is only enough for two or three hours of lighting a day, so the street light system should be replaced regularly.
Pay attention to adjust the angle of the solar panel to ensure that the angle of the solar street light panel is correct, and the solar energy can be fully obtained and fully charged, then the normal lighting time can be guaranteed.
Solar Street Light with solar power system made in China has reached a certain service life if the battery has charge & discharge times, the power will gradually decrease as the number of uses increases. Therefore, the lighting time of solar street lights will gradually decrease after using for more than 3 years. This is a normal phenomenon.
The above precautions for using solar street lights in winter are shared here. So in order to use solar street lights in winter, as usual, try to clean them manually or mechanically when there is snow on the battery panels. In addition, when installing solar street lights time to fully consider the local climatic conditions.
