For solar street lights currently on the market, the battery is usually placed on the top of the light pole or inside the light pole.
First of all, placing the battery on the top of the floor lamp is a common design. The advantage of this design is that it can make full use of solar energy, because the top of the light pole is the most likely place to receive sunlight. Solar panels are usually installed on top of light poles and can be directly exposed to sunlight to completely absorb solar energy and convert it into electrical energy. The battery is placed in a battery box, usually located on top of the light pole for easy maintenance and battery replacement. The downside to this design is that the battery is exposed on top of the street light and is easily affected by weather, such as rain, sand, etc., which may affect battery life and performance.
Another common design is to place the battery inside the light pole. The advantage of this design is that it protects the battery from bad weather and extends its lifespan. The battery is usually placed in a battery box inside the light pole. The battery case is waterproof and dustproof to protect the safety of the battery. The disadvantage of this design is that the battery is placed inside the light pole, requiring more space to install the battery box, which can increase the volume and weight of the light pole.
In addition to the two common designs above, there are also innovative designs. For example, some solar street lights place the battery at the bottom of the light pole to reduce the size and weight of the light pole.x while protecting the battery from bad weather. There are also solar street lights that place the battery on the side of the light pole for easier maintenance and battery replacement.
In general, the battery placement position of solar street lights can be determined according to actual needs and design requirements. Whether placed at the top, inside or bottom of the street light, factors such as full use of solar energy, battery safety and maintenance should be considered. With the continued advancement and innovation of technology, I believe there will be more and better designs of solar street lights in the future.
