Do outdoor solar street lights work in rainy days？

Outdoor solar street light is a very safe and convenient product. Compared with ordinary city circuit lights, outdoor solar street lights have many advantages. Because there is no need to dig pits to bury cables, it saves time and effort, and can also avoid accidents such as leakage and fire. The outdoor solar street lights are energy-saving and environmentally friendly. Nowadays, the country also strongly supports the use of outdoor solar street lights and they have been installed in many places. However, some people may ask what if the solar panels can’t generate electricity if it is rainy or foggy.

As we all know, outdoor solar street lights rely on the solar panels to absorb sunlight and convert them into electrical energy for lighting purposes. However, the sunlight mentioned here is not absolute. It does not mean that the solar panels will only work when the sun is shining. Generally speaking, as long as there is light, solar cells can store energy. The stronger the light, the higher the conversion efficiency. Therefore, when the light intensity is not strong, the battery panels will still store energy for the battery, but the stored electricity is relatively small. The electricity stored on the day may not be enough to turn on the lights at night. When this occurs, the previously stored energy of the battery needs to be used. When the storage battery can't keep up with its external supply, the light will not turn on.

There is an intelligent controller in the outdoor solar street light. When there are multiple cloudy and rainy days and the solar panel can’t absorb the sunlight, the intelligent controller will reduce the loss of its discharge and ensure that it can survive several cloudy and rainy days. This kind of controller is more convenient and can ensure that the outdoor solar street light can be used normally in rainy days.

Under normal circumstances, the default number of cloudy and rainy days for outdoor solar street lights produced by most manufacturers is three days. The number of cloudy and rainy days for all in one outdoor solar street lights will be longer, ranging from five days to seven days. The reason why outdoor solar street lights can continue to work in cloudy and rainy days is that part of the battery stores electric energy. Without solar energy conversion, the street lights can continue to work for a period of time. However, when the original stored electricity is exhausted, outdoor solar street lights will stop working when they can’t be supplemented by solar energy all the time.

The photovoltaic components and batteries of outdoor solar street lights determine the number of rainy days, so these two parameters are important reference factors for purchasing outdoor solar street lights. If your local weather is relatively humid and there are more cloudy and rainy days, if there are more continuous cloudy and rainy days, then choose outdoor solar street lights that support more cloudy and rainy days. Or you can choose a professional outdoor solar street light manufacturer, tell the professional staff your requirements so that the supplier can customize the outdoor solar street lamp according to your local climate.
