Most solar street lights can be used when there is no sunshine on rainy days. The solar street light itself and the electrical system are waterproof and have batteries to store energy, and certain rainy weather conditions must be taken into account when designing. So solar street lights can work in rainy days. If it is cloudy and rainy for several days in a row, it depends on how many consecutive rainy days the street lamp configuration and technology can support.
1. Under normal circumstances, the default number of rainy days for solar street lights produced by most manufacturers is three days, and the number of rainy days for integrated solar street lights will be longer, ranging from five days to seven days. That is to say, within the specified number of days, even if the solar street light cannot replenish solar energy, it can still work normally, but once this number of days is exceeded, the solar street light cannot be used normally.
2. The reason why solar street lights can continue to work in rainy days is because a part of the battery stores electric energy. In the absence of solar energy conversion, street lights can continue to work for a period of time, but when the original stored electricity energy consumption When the solar energy is exhausted but still cannot be supplemented by solar energy, the solar street light will stop working.
The basic working principle of solar street lights is that the solar battery pack converts the sun’s radiant energy into electrical energy during the day, which is stored in the battery by the intelligent controller, and the battery is controlled by the intelligent controller to discharge the street lights at night, and the lighting time is reasonably allocated according to user requirements.
For solar street lights, in order to meet the continuous use of rainy days for a longer period of time, there are three key points in the design. From the hardware point of view, it is necessary to increase the configuration: First, improve the conversion efficiency of solar panels. On the one hand, you can choose the conversion efficiency per unit area. Higher solar panels, on the other hand, can also increase the area of the solar panel, that is, increase the power of the solar panel; secondly, increase the capacity of the battery, because solar energy is an energy that cannot provide continuous and stable power supply, so a kind of power storage is necessary The device stores electricity and outputs it in a stable and sustainable manner. The third point is from a technical point of view, that is, to realize intelligent power regulation through technical means, intelligently judge recent weather conditions, and reasonably plan discharge power.
