Can Solar Power Street Light still work normally in rainy days?

Solar power street light is getting through solar panel absorbing sunlight, to convert solar power into electric power, then storing into battery and the battery provide electric power for LED lamp to work in night. Can solar power street light still work normally if it is rainy day?

Firstly, we should know the working principle of solar power street light. Its working principle is that solar panel converts solar power into electric power in daytime, getting though smart controller to store into battery. The smart controller controls battery to discharge for LED lamp to work in night. The lighting time can be set to distribute according to customers’ requirement.


Regards to solar power street light, if need meet the LED lamp to work under more rainy days, it should notice three factors when designing it. From its hardware, its allocation need be increased. The first one is to improve the conversion rate of solar panel, one the one hand, the higher efficient solar cells can be adopted, on the other hand, the size of solar panel can be enlarged. The second is to increase the battery capacity, as solar power can’t continue to provide stable power, it should use a battery to store these electric powers, then output at stable and continuous power. The third is via technological method to realize intelligent power adjustable, to smart adjust climate state and reasonable to distribute the output power.


In addition, quality is also important, the quality of solar panel and battery would decide the lifespan of solar power street light.

After learning about the basic working principle for solar power street light, now let us talk about these questions.

1. Can solar power street light work normally in rainy days?
There are waterproof and power storage design for solar power street light, and some rainy days should be considered when designing it. Therefore, solar power street light still can work in rainy days. If there are many days to continue rainy, the lighting days of solar power street light is decided by its allocation and technology.


2. Can solar power street light be charged in rainy days?

Yes, solar power street light also can be charged in rainy days, but the power of charging is weak, its power state of charging is different in different rainy situation. There is battery for solar power street light, the battery is charged automatically when sunlight is sufficient, the battery can support solar LED lamp in rainy days. In rainy days, solar panel also can convert sunlight into electric power, but the power is weak.


3. Could solar power street light bright every night in a year?

Of course, it can’t continue to bright every day unless don’t have more rainy days. After learning the working principle of solar power street light, we know that the working mode of solar power street light should coordinate with the law of conservation of energy, according to energy conservation law, if there are too many days to continuous rainy, the battery would not be able to provide power for LED lamp to work, because it can’t get enough charged. Usually, the battery of solar power street light would have some remain power to backup for rainy days, at the same time, battery also can be charged some power in rainy days, so, solar power street light still can work normally in rainy days. But if the rainy days surpass the setting time, the solar street lamp would not be able to light all night.

As above introduction, we can learn that solar power street light still can work normally in rainy days, because its storage battery would backup for some rainy days. Moreover, solar power street light also can be charged in rainy days, just the charging power is weak. But solar power street light can’t work all the time if there are many rainy days. Usually, solar power street light can work normally for 3 rainy days, some can work 10 rainy days under advanced technology. But if the rainy days are continuous to over 10 days, it would be difficult for solar power street light to work all night.
