Solar street lights use the heat of the sun to store electricity and generate electricity. Many people think that they can only be used when there is sun on a sunny day. In fact, this is not the case. We can see that street lights can still be used as usual even on rainy and cloudy days. What is the principle? Here is a brief introduction for everyone.
First of all, solar street lights rely on batteries to store the sun's heat and then convert it into electricity for street lights to illuminate. Even on a cloudy day, it can absorb the heat of the sun. If there is no sun, the battery can store electricity, so you don't have to worry about no street lights when you go out on a rainy and cloudy day.
Secondly, how long the solar street light can be used continuously in rainy weather still depends on the size of the battery. If the battery is of good quality and has a lot of electricity stored, it can be used continuously for more than ten days on a rainy day. If the battery The power storage capacity is small and the quality is not good, so the use time will not be too long. Therefore, when choosing a new energy street lamp, you must pay attention to the quality of the battery , which is related to the life of the street lamp.
In summary, in rainy weather, especially when traveling at night, there is no need to worry about the lack of street lights, because street lights can work normally, which is also an advantage of new energy street lights.
