“How long can lithium battery solar street lights from solar street light manufacturers operate continuously during rainy days?”

Therefore, it can be summarized that if a lithium battery solar street light is fully charged, it can maintain operation for up to a week during rainy days, which is seven days. The main reason is that lithium battery solar street lights rely on solar radiation energy converted into electrical energy. To increase their working duration in overcast weather, choosing the appropriate lithium battery is essential.

Currently, the preferred choice for solar street light manufacturers is generally the split-type street lights. The lead-acid battery sets are either mounted above the lamp post or buried underground beside the post in a ground box. The alternative is to place the lithium battery on the back of the solar panel assembly.

Voltage Platform: The voltage platform for lithium batteries is greater than 3V, while for lead-acid batteries, it is 2V.

Safety: The safety levels of lithium batteries (like lithium manganese oxide and lithium iron phosphate) differ due to the materials used, while lead-acid batteries are a well-established technology with better safety than lithium batteries.

Environmental Friendliness: Lithium batteries have no pollution (not absolute), whereas lead-acid batteries contain heavy metal lead pollution.

Discharge Characteristics: Simply put, with the same capacity, under high current discharge conditions, lithium batteries can provide approximately 30% more power than lead-acid batteries.

Solar street lights can automatically adjust their brightness based on the sky brightness throughout the 24 hours and various personal needs. Simultaneously, the system can allocate the ratio of lithium battery solar cells for lighting and storage, and discharge according to the light source’s brightness, ensuring that the entire system is fully charged on sunny days. Additionally, LED light sources are used for illumination, allowing for more energy and power savings. It can also provide effective lighting for continuous rain and cloudy days for up to 7 days.

The above provides a complete answer from solar street light manufacturers regarding how long lithium battery solar street lights can continuously operate during rainy days. We hope this information is helpful, and you can refer to the parameters provided.
