Does street light solar panel voltage have anything to do with lithium battery size?

The voltage of the solar panel of the solar street light is related to the capacity of the lithium battery.

First, the solar panels of solar street lights absorb sunlight and convert it into electrical energy. Solar panels generally use photovoltaic cells, made up of several photovoltaic cells. The working voltage of each photovoltaic cell is generally between 0.5V and 0.6V, so the total voltage of the solar panel depends on the number of photovoltaic cells. If there are 10 photovoltaic cells on a solar panel, the total voltage will be between 5V and 6V.

Secondly, the capacity of the equipped lithium battery will also affect the performance of solar street lights. The capacity of lithium batteries is typically measured in milliamp-hours (mAh), which represents the amount of current the battery can deliver. Solar street lights mustt store enough electricity to be used at night, so they must be equipped with lithium batteries of appropriate capacity. Generally speaking, the lithium battery capacity of solar street lights is between 1000mAh and 5000mAh.

There is a certain relationship between the voltage of the solar panel of the solar street light and the capacity of the lithium battery. The voltage of the solar panel must match the voltage of the lithium battery in order to convert the solar energy into electrical energy and store it in the lithium battery. Generally speaking, the voltage of solar panels should be slightly higher than that of lithium batteries to ensure efficient charging. For example, if the lithium battery voltage is 3.7V, then the solar panel voltage can be selected around 4V.

To summarize, the solar panel voltage of the solar street light is linked to the capacity of thelithium battery. The voltage of the solar panel should match the voltage of the lithium battery, and the capacity of the lithium battery should be determined according to the usage requirements of the solar street light. Only when the voltage of the solar panel and the capacity of the lithium battery are reasonably matched can the normal operation of the solar street light be ensured.

A small cell in a solar panel measures 0.5 volts. Solar panels are made up of cells. Regardless of the size of a single cell, the voltage is between 0.48 and 0.5 V. Therefore, the voltage of a panel consisting of 36 cells connected in series is generally between 17.3 and 18 .0 V. As long as 36 cells are connected in series, the voltage will remain in this range.
