In recent years, the government has placed great emphasis on rural construction, and the construction of new rural areas naturally includes streetlights. Solar streetlights have been widely adopted due to their easy installation and ability to save electricity costs without the need for grid power, making them the ideal choice for rural lighting. However, why are more and more solar streetlights using lithium batteries? Below, we will introduce this topic.
1. Lithium batteries are small in size and lightweight, making them easy to transport. Compared to lead-acid gel batteries, the lithium energy storage system used in solar streetlights of the same power is about one-third the weight and volume. This simplification in transport leads to reduced transportation costs.
2. Solar streetlights using lithium batteries are easier to install. Traditional solar streetlights require a battery pit and a ground box to seal the battery. In contrast, the installation of lithium battery solar streetlights is much simpler, as the lithium battery can be directly mounted on the bracket, either in a hanging style or an embedded style.
3. Maintenance of lithium battery solar streetlights is convenient. When maintaining a lithium battery solar streetlight, the battery can be removed directly from the lamp pole or under the battery panel. However, traditional solar streetlights require digging up the batteries buried underground, making the process significantly more complicated compared to lithium battery models.
4. Lithium batteries have a high energy density and a longer lifespan. Energy density refers to the amount of energy stored in a certain space or mass. The higher the energy density of the battery, the more power can be stored in a given weight or volume. Many factors influence the lifespan of lithium batteries, among which energy density is a very important internal factor.
These are the reasons for the use of lithium batteries in solar streetlights. Additionally, since solar streetlights are a one-time investment for long-term usage, it is advisable not to purchase products that are too low in price. Low-cost solar streetlights generally have lower quality, which may increase the likelihood of maintenance in the future.
