What is the voltage of lithium battery for solar panel street lights? How long can it be used?

Firstly, the application of solar street lights mainly relies on solar panels, which typically have a voltage of 17.

5V and these two specifications are currently the mainstream voltage specifications on our market. Why is the voltage of this solar panel mentioned? It is because the voltage design of the solar panel is for charging the batteries of and respectively.
Of course, you can also connect multiple batteries in series, so that the solar panels can also be connected in series for charging.
The solar panel generates direct current, and after being charged into the battery, the voltage output from the battery is also//These are several commonly used specifications in solar street lights.
At present, the light sources of solar street lights on the market are specially designed for solar panels, so the conventional voltage is//36/, which is the mainstream. Of course, there are also higher ones, such as/, etc.

What is the size of lithium battery for solar street lights?

The most commonly used lithium-ion battery in the solar street light industry now is type. SONY, a Japanese company, established a standard lithium-ion battery model to save costs, where 18 represents diameter, 65 represents length, and 0 represents cylindrical battery. The battery is made by professional typesetting and welding, as the positive and negative poles of lithium batteries are separated. So the possibility of it experiencing a short circuit has been reduced to the extreme. In addition, a protective plate needs to be installed to prevent overcharging and overdischarging of the battery. The commonly used single cell voltage is 3.2V, and we usually have 4 strings. To get back to the point, what size of lithium battery should be used for solar street light sources? The capacity of the battery is related to power, lighting time, and the number of rainy days. Below is a list to explain
Light source power (watts), working location, working time, ensuring average rainy days, sunshine, battery board, lithium battery controller.
30 watt Yangzhou (peak sunshine 3.7) 6 hours 3-5 days 4 hours
8 hours 3-5 days 4 hours
10 hours 3-5 days 4 hours
6 hours (front 3, back 3) 3-5 days 4 hours
6 hours (front 2, back 4) 3-5 days 4 hours
8 hours (front 4, back 4) 3-5 days 4 hours

8 hours (front 2, back 6) 3-5 days 4 hours

Customers can calculate their own configuration based on the capacity of our lithium battery, as solar panels are calculated based on the peak sunlight in Battsys, which varies in different regions. If you need to calculate the configuration of solar street lights, you can contact us.
