How Long Can a Solar Energy Street Light Stay On?

With the research on new energy sources, solar energy has become one of the most popular new energy sources. With the development of the Internet, the solar store online has appeared in people's vision. More and more people buy solar products, such as solar street lights in solar store online. But before buying, we have to learn solar street lights.


1. What is the solar energy street light

A solar energy street light is an independent lighting system. Put it simply, the solar energy street light generates electricity for its own use. It does not need to be connected to 220V thermal power. During the day, solar energy is converted into electrical energy through battery panels and stored in lithium batteries. When it is dark, the intelligent street light control system uses lithium batteries to supply power to the solar energy street light. The normal design of continuous rainy days is 7 days, if the battery power detection automatic power reduction controller is used, it may be extended to about 35 days. And we know that under normal circumstances there will not be a whole month without the sun, so how long can solar street lights be lit? You need to learn clearly before buying at the solar store online.


2. How long can the solar energy street light stay on?

For the solar energy street light battery panel, it is made of pure silicon board as the main material,whose life span can reach more than 25 years. The life span of LED light source is more than 50,000 hours, and for normal use it can also be as long as about 10 years. The current commonly used lithium battery for solar street lights has a life span of more than 5 years.


The service life of solar panels is generally as long as 25 years. As long as it's a product from a regular solar panel factory, the service life of the light pole can reach more than 30 years. As long as the solar energy street light controller is used in the correct way, it will not cause much threat.


The service life of LED light source and battery is generally 3 to 5 years. But if the overall system configuration is too small and the solar street lamp is always used in a state of power loss, the battery will decay quickly, which will also affect the service life of the battery. Some may have to be changed every 2 to 3 years. When we choose batteries, we must consider the daily charging capacity of the solar panel, the daily power consumption of the light source, and the number of cloudy and rainy days. Generally, we have to reserve 3 to 5 days of cloudy and rainy days, so that the solar energy street light can be used normally.
