          Tips for using solar street lights in winter
          Time:2020-04-07  Traffic:

          In winter, the sun will move south, and the sun's altitude will decrease, resulting in insufficient light. Therefore, the solar panel should be placed where the solar energy shines. The solar panels have not been cleaned for a long time, and there is too much dust, which affects the power generation. In some places, it is because it often snows, and the snow covers the solar panels to cause insufficient power generation.


          Tips for using solar street lights in winter


          1: The solar panel receives a certain amount of light energy per unit time. Under the same conditions, the solar panel's photoelectric conversion efficiency is different. The lighting conditions are not as good as in summer. In winter, if you want to fully charge the battery while there is sunlight, it means that the requirements for the photoelectric conversion efficiency of solar panels are also higher.


          2: The light in winter is not as good as in other seasons. The solar panel is not generating enough electricity. At the same time, the discharge of the battery in winter is only 70% of that in summer. The battery power is only enough for two or three hours a day to run out of electricity, so the street lamp system should be replaced regularly.


          3: Pay attention to adjust the angle of the solar panel to ensure that the solar street lamp panel angle is correct, can fully obtain solar energy and charge in full, then the normal lighting time can be guaranteed.


          4: The weather is cold in winter, and the battery will be damaged by frost, which is easy to cause insufficient discharge. Usually in cold areas, the battery should be buried at least 1 meter deep, and 20 cm of sand should be laid on the bottom.
