Battery placement for solar street lights

31 Jul.,2025

The placement of batteries for solar street lights is a crucial part of system design, which directly affects energy storage efficiency, equipment life, and operation and maintenance costs.

 

When talking about solar streetlights, the first thing that comes to mind is solar panels and batteries. Let's not talk about solar panels for now. Today, let's analyze the placement of batteries. In detail Where is the most practical?

 

When installing solar street lights, most places will habitually bury the batteries under the land on both sides of the street light poles. This has two purposes: one is to save space, and the other is to prevent theft. There is another good way, which is to fix the solar battery on the top of the light pole, which can also prevent theft and will not take up space.

 

We make a systematic comparison of the two schemes. There are two ways to bury the battery underground. One is to dig a square pit on the ground with a size similar to the battery buried box, and then put the battery down and bury it directly. The other method is to dig a pit with a width and height slightly larger than the battery buried box, and then build four walls with bricks in the pit to separate it from the surrounding soil, and then lay a layer of bricks below and apply cement all over it. This can play a good waterproof role. Which of these two underground methods is more practical naturally pales in comparison?

The hanging type solution does not require digging a pit on the ground but welds an iron box corresponding to the size of the battery on the top of the solar street light pole in advance, and then directly puts the battery in it. This method can save a plastic buried box, and there is no need to worry about the service life being affected by water ingress and moisture.

 

Compared with the two, the hanging-type solution is more practical. Why do I say that? First of all, it is better to put the buried battery in a square pit in the wall. It is very unsafe to bury it directly in the soil. The unsafety here is not afraid of theft, but easy to get water. After getting water, the impact on the life of the solar battery is very large. Moreover, all the batteries buried underground will be very laborious to replace in the future because now to beautify the streets, many roads are cemented. The service life of the battery of the solar street light is generally 5 years, that is, it needs to be replaced once after 5 years. Then when replacing it, all the cement around the lamp pole must be smashed, and then the position must be found bit by bit, because after all, the time is too long, and the exact location of the buried box is difficult to find.

 

The hanging-type battery can make up for these shortcomings. First, there is no need to worry about it getting wet. Second, it is very convenient to replace. You only need to open the upper cover of the solar cell box to directly take out the battery for replacement. So in this comparison, the hanging-type solution is more practical.
