Under normal circumstances, the default number of cloudy and rainy days for solar street lights produced by most solar street light manufacturers is two to three days. The number of cloudy and rainy days for integrated solar street lights will be slightly longer, ranging from five days to seven days. Explain that in the case of continuous raining of solar street lights, as long as the raining time does not exceed the number of days specified in the product, even if the solar street lights cannot supplement the solar energy, they can still work normally, but once this number of days is exceeded, the solar street lights will be exhausted The stored power cannot be used normally.
The reason why solar street lights can continue to work in the case of rainy days is because a part of the battery stores electrical energy. Without solar energy conversion, the street lights can continue to work for a period of time, but when the original stored electricity is exhausted The solar street light will stop working when it is not supplemented by solar energy.
In fact, very little is known about solar street lights. One parameter of solar street lights is called the number of rainy days, which refers to the number of days that solar street lights can work normally under continuous rainy days without solar energy supplement. According to these parameters, everyone can judge that the solar street lamp can work normally in rainy days and can work for several rainy days.
The photovoltaic modules and batteries of solar street lights determine the number of rainy days, so these two parameters are important reference factors for purchasing solar street lights. If your local weather is relatively humid and there are more cloudy and rainy days, you must choose a solar street light with more cloudy and rainy days.
