Can solar street lights work normally on rainy days?


Solar street lights, as the name suggests, are street lights powered and stored by solar energy. How can solar street lights work normally in the long rainy weather without the sun?

Firstly we need to understand the working principle of solar street lights. The basic principle of solar street lights is that the solar battery pack converts the radiant energy of the sun 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 lamp at night. , According to user requirements, reasonable allocation of lighting time.

For solar street lights, there are three main points in the design for continuous use in longer rainy and rainy days. From the hardware, it is necessary to increase the configuration: firstly, to 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 not an energy source that can continue to provide stable power, then a kind of power storage 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 achieve intelligent power adjustment through technical means, intelligently judge the recent weather conditions, and plan the discharge power reasonably.

In addition, the choice of quality is also very important. The quality of battery boards, batteries and other accessories also greatly affects their service life. Taking the battery as an example, to give a simple example, the mobile phone charging treasure is equipped with a lithium battery, some The charging treasure has a large capacity, but it will not be able to fill up the mobile phone in a long time. The problem is that it is equipped with a battery of poor quality, which causes the battery to decay quickly; the same is true of solar street lights. Good or bad has a profound impact on it.

With these points in mind, you can better extend the use of solar street lights in rainy and rainy days.

Can solar street lights work on rainy days?

The solar street light itself and the electrical system are designed with waterproof and batteries to store energy, and certain rainy days must be considered when designing. So solar street lights can work on rainy days. If it has been rainy days for several days, it depends on how many consecutive rainy days the street lamp configuration and technology can support.

Can solar street lights be charged in rainy days?

The solar panel can also be charged during rainy days, but the amount of charge will vary depending on the degree of rainy days. Solar street lights are equipped with battery charging and discharging devices, which usually recharge themselves when the sun is full, and maintain the street light power supply on battery power in rainy days. The solar energy is charged under the sun's light. On cloudy days, the sun's light is weaker and the charge capacity is relatively weaker.

Some manufacturers say that solar street lights can light up 365 days a day, is this true?

After understanding the working principle of solar street lights, we know that the working mode of solar energy needs to follow the principle of energy conservation. Similarly, according to the principle of energy conservation, if there is a long continuous rainy day, because the charge is less than the discharge, some manufacturers promote "solar "Street light 365 lights every day" is inaccurate. This is because some manufacturers are wiping the side ball, playing word games, and misleading consumers. Due to the different product design and positioning, the general solar street lights will have different margins to resist continuous rainy days. At the same time, because the rainy days can also be recharged, the lights can be turned on, but the rainy day time exceeds the set time. It is impossible to turn on the lights overnight. Therefore, if a manufacturer is still promoting that the lights are on every day of 365, just ignore it.
