Why Bury Solar Light Street Lamp Battery Underground?

Solar light street lamps convert sunlight into electrical energy for lighting. They have the advantages of energy saving, safety, environmental protection and durability, low maintenance costs, clean and pollution-free, and are favored by all walks of life. Whether it is rural roads, park communities, urban streets, large and small public places, we can always see solar light street lamps. It has become the main force of outdoor lighting and plays an important role in urban construction.

The failure rate of solar light street lamps is very low, and the service life is relatively long. However, there is a component in solar light street lamps that is easy to wear and has a service life of only about 5 years, and that is the battery. Generally speaking, the battery of solar street lamps is buried underground.

The buried type is mainly related to the type of battery. Solar light street lamp batteries mostly are gel batteries and lead-acid batteries, which are relatively large and heavy, and can't be placed in the lamp holder or in the air, so they can only be buried. In addition to this reason, burying the battery of the solar street light in the ground certainly has other benefits.

1. Anti-theft

Battery is an important part of solar light street lamps, and the price is relatively expensive, so they will naturally be targeted by some criminals. Therefore, the battery must be buried deep underground, and not too shallow, otherwise it is easy to be stolen.

2. Antifreeze

The battery can be used normally at minus 30℃-60℃. However, in an extremely cold environment, the battery's endurance will be reduced, and some of them will stop working. Therefore, if solar light street lamps are to be installed in colder areas, it is still necessary to bury the battery at a depth of less than 2 meters, because it can maintain a certain temperature.

3. Prevent water from entering the battery

Batteries are afraid of water ingress, and batteries are no exception. Although the outer layer of the battery is waterproof. In order to have a better waterproof effect, it needs to be covered with cement around it. There are also some street lights that use waterproof battery boxes for waterproofing.

Nowadays, many solar light street lamp manufacturers will choose lithium batteries. Relatively speaking, they are much easier to install. They are small in size and have many charge and discharge times. The battery can be installed under the solar panel, but the battery needs to be locked in the battery box. The higher installation location can reduce the possibility of theft to a certain extent. Compared with gel batteries and lead-acid batteries, lithium batteries have better performance, lighter weight and longer service life. Most of the integrated street lights use lithium batteries, which are simple to install and basically do not require maintenance. Batteries are one of the most core accessories in solar street lights, so we try to choose components with good performance when configuring solar light street lamps, which can prolong its service life.
