​All In One LED Solar Street Light vs Split Solar Streetlight

As the name suggests, an all-in-one LED solar street light integrates all components into a single unit. This includes the solar panel, rechargeable battery, LED light source, controller, and mounting bracket. But what sets these two types of street lights apart? Is it merely a structural difference? Let's explore this in detail.

Battery 

Split solar streetlights typically use lead-acid batteries, whereas all-in-one LED solar street lights utilize lithium batteries. Lithium batteries have three times the charge and discharge cycles of lead-acid batteries, directly impacting their lifespan. Lead-acid batteries operate down to -5°C, but their capacity diminishes below 5°C and they risk freezing below -10°C, leading to temporary failure. In contrast, lithium batteries, being solid-state, function down to -20°C without capacity loss. Even at temperatures between -20°C and -30°C, lithium batteries only lose about 30% capacity. In regions like Northeast China, Xinjiang, and Tibet, where winter nighttime temperatures can drop below -10°C to -30°C, lead-acid batteries may fail, causing the lights to go out. All-in-one LED solar street lights, however, perform reliably in low temperatures. In summary, lithium batteries outperform lead-acid batteries in both charge cycles and low-temperature performance.

Installation 

Installing split solar streetlights is more complex than installing all in one solar led street light. It involves digging a ground cage pit for the light pole and a separate pit for the battery box, which must be protected from water ingress. After burying the battery, the solar panels and lamps need to be installed. In contrast, installing an all-in-one LED solar street light is straightforward: dig the ground cage, install the lamp, and erect the light pole. The integrated design of the all-in-one system, which houses the solar panel, controller, and light source within the lamp pole, speeds up installation and reduces construction costs. However, the split type offers more design flexibility due to its separate components.

Maintenance 

Repairing split type solar street light is more complicated. When a street light malfunctions, the manufacturer must send technicians to the site to inspect various components like the battery, photovoltaic panel, LED lamp holder, and wiring. Some manufacturers may not even provide on-site maintenance. For all-in-one LED solar street lights, users can simply send the integrated unit back to the factory for repairs.

Lighting Efficiency 

The larger the area of the battery panel, the higher the photoelectric conversion efficiency, and the battery capacity is proportional to its volume. Therefore, the compact design of integrated LED solar street lights limits the area of the battery panel and the battery volume, making them unsuitable for locations with high lighting requirements. They are best used in areas with moderate lighting needs. Split solar streetlights, on the other hand, offer greater flexibility.

From this comparison, we can see the differences between all-in-one LED solar street lights and split types. Users can choose the appropriate street lamp based on their specific needs.
