It is 12V or 24V. The voltage of a solar panel mainly depends on the solar panel type, size, cells, etc. Whether it be open circuit voltage, maximum power voltage, or nominal voltage, you will find it all in the datasheet of the manufacturer. Generally, the nominal voltage of any solar panel is 12V or 24V.
Most common solar panels include 32 cells, 36 cells, 48 cells, 60 cells, 72 cells, or 96 cells. Each PV cell produces anywhere between 0.5V and 0.6V, according to Wikipedia; this is known as Open-Circuit Voltage or V OC for short. To be more accurate, a typical open circuit voltage of a solar cell is 0.58 volts (at 77°F or 25°C).
There are three types of solar panel voltages. The voltage that is recorded when there is no load connected to the solar panel is called Open Circuit Voltage. The circuit is open as there is no load, so there is no flow of current. A multimeter is connected at the terminals of the solar panel directly without having a load.
With solar panels, we can charge batteries, and batteries usually have 12V, 24V, or 48V input and output voltage. It is the job of the charge controller to produce a 12V DC current that charges the battery. Open circuit 20.88V voltage is the voltage that comes directly from the 36-cell solar panel.
Here is the nominal and open circuit voltage chart for 32-cell to 96-cell solar panels: As we can see, solar panels produce a significantly higher voltage (VOC) than the nominal voltage. The actually solar panel output voltage also changes with the sunlight the solar panels are exposed to.
Nominal Voltage. This is your typical voltage we put on solar panels; ranging from 12V, 20V, 24V, and 32V solar panels. Open Circuit Voltage (VOC). This is the maximum rated voltage under direct sunlight if the circuit is open (no current running through the wires). Example: A nominal 12V voltage solar panel has an open circuit voltage of 20.88V.
