How do solar light towers work and what are their advantages

2023/12/21

In recent years, solar energy as a new energy in front of people's eyes, with the continuous development of solar energy technology, such as lighting towers such a relatively high power consumption products can also use solar energy as their own energy source.

How does a solar power light tower work?
First of all, we all know that a complete solar power light tower is composed of axle, drawber, canopy, mast, solar panel and LED light group. The canopy is loaded with many important components, such as battery packs, inverters, controllers, generators and so on. The working principle is that the solar panel uses sunlight to generate electricity, and is stored in the battery pack, and then the battery pack supplies power to the LED light pack.

Role of controller
If the heart of the car is the engine, then the controller is the heart of the solar power light tower. The controller can control the charging and discharging of the light tower, the height of the mast, the brightness and Angle of the lamp, etc., and can also detect the battery power.

Why load inverter?
Near the pole, there are times when there is not enough light for the panels to generate enough electricity for the solar power light tower to work, because the light is not stable. Therefore, light tower used in these locations need to be equipped with diesel or gasoline generators, and equipped with inverters and mains charging ports. Since the generator generates alternating current, the mains power is also alternating current (AC), but the battery pack and LED light pack that store the power can only accept direct current (DC). Therefore, it is necessary to use an inverter to convert alternating current (AC) into direct current (DC).

The advantages of solar power light tower
The main advantage of solar power light towers compared to those using diesel/gasoline as the main energy source is energy saving.
We have done a test, the use of diesel/gasoline for energy generation, the storage of 1200Ah battery fully charged (1200Ah battery pack can work for more than 12 hours of 6*100W LED light pack), it takes about 3 hours. Consumption of diesel 4.65L or 6L gasoline. Charging the battery pack with three 575W solar panels takes 5.5 hours and uses "0" fuel. Although the charging speed of solar panels is relatively slow, about 1.85 times that of diesel and gasoline, it has no energy consumption. And even on rainy days, it only takes seven hours to fully charge, while most parts of the world get more than eight hours of sunshine a day.
It can be seen that the biggest advantage of solar power light towers is that there is no energy cost, which protects the environment and saves costs. And as people's awareness of environmental protection gradually increases, many countries or regions have issued regulations to strictly limit the use of diesel/gasoline generators. Therefore, in the future, solar power light towers will become more and more common.
