Detailed Explanation of The Working Principle And Continuous Lighting Time of Solar Street Lights on Cloudy And Rainy Days
Sep 23, 2024
Solar street lights, as the name implies, are street lights that use solar energy to charge. During the day, when sunlight shines on the solar panels, the panels convert light energy into electrical energy and store it in the battery. At night or when the light is weak, the electrical energy in the battery is supplied to the LED lamps through the controller to light up the street lights. The intelligent controller is not only responsible for the charging management of the battery but also automatically controls the switch of the street lights according to the changes in ambient light. But there is a problem that must be considered. If there is no sun on a rainy day, how will it work?
In rainy weather, due to the obstruction of clouds, solar radiation is significantly reduced, resulting in a significant reduction in the solar energy received by the solar panels. This directly affects the power generation efficiency of the panels, resulting in a corresponding reduction in the amount of electricity generated. However, solar street lights suppliers believe that this problem is not difficult for outdoor solar street lights.
The design of solar powered street lights has taken this situation into consideration and has taken a series of measures to ensure its normal operation in rainy weather. Solar panels collect less energy on rainy days than on sunny days, but that doesn't mean they don't collect any energy. In fact, solar street lights collect more energy during the day than they consume at night, so there is enough energy to charge the street lights and there is excess power to charge the batteries.
When solar street light manufacturers design their systems, they also determine the size of the solar panels and batteries based on the specific location where the street lights are installed, based on data from the Meteorological Bureau, and increase the capacity of the batteries, which means that even without sunlight, the solar energy street lights have enough power to last for a while. So, with the ability to generate power even on cloudy days, we can ensure that your lights will shine night after night.
To ensure that outdoor solar street lights can be used for a long time in rainy weather, three key aspects need to be considered during the design phase.
First, the hardware configuration needs to be enhanced, which can be achieved by using solar panels with higher conversion efficiency per unit area or increasing the size of the solar panels to generate more electricity.
Secondly, the battery capacity needs to be increased because solar energy is not a continuous and stable power source. The energy stored in the battery ensures a stable and sustainable power output. The battery is the key to keeping outdoor solar street lights working in rainy weather. On sunny days, the solar panels store excess electricity in the battery. In this way, in rainy weather, even if the power generated by the solar panels is insufficient, the reserve power in the battery can continue to power the street lights.
Thirdly, intelligent power regulation technology can be used to adjust the discharge power according to weather conditions and optimize energy use. The intelligent charge and discharge controller can automatically adjust the switch of the street lights according to the changes in ambient light and take energy-saving measures when the battery power is insufficient, such as reducing the brightness of the street lights or extending the switching interval time to extend the working time of the street lights.
It is not necessarily a bad thing for solar street lights. Solar panels can be washed for free in rainwater, and rainwater will wash away the debris and dust accumulated on the panels, which also means that when the sun comes out, they can collect sunlight more efficiently. In short, solar energy street lights can still work normally in rainy weather, mainly due to their built-in battery energy storage system, the waterproofness of solar panels that can be efficiently converted, and the intelligent control function.
Therefore, solar street light manufacturers believe that although rainy weather will affect the power generation efficiency of solar panels, through reasonable design and configuration, solar street lights can still provide people with stable and reliable lighting services. With the continuous advancement of technology and the continuous promotion of its application, we believe that solar energy street lights will play a more important role in future urban lighting and will bring more and more convenience to your life!
