For panels intended for use with as PWM CC to charge batteries, the "nominal" voltage of the panel is sometimes taken to be the nominal voltage of the battery bank it is to be used with. Using that convention, a panel with Vmp=18 may be called a "12 volt panel." Similarly, a panel with Vmp=36 may be called a "24 volt panel".
The relationship between watts and volts in a solar panel can be understood using Ohm''s Law: Power (in watts) equals Voltage multiplied by Current. This means that if you have a fixed wattage rating for your solar panel, such as 100 watts, varying the voltage will result in changes to its current output.

To be more accurate, a typical open circuit voltage of a solar cell is 0.58 volts (at 77°F or 25°C). All the PV cells in all solar panels have the same 0.58V voltage. Because we connect them in series, the total output voltage is the sum of the voltages of individual PV cells. Within the solar panel, the PV cells are wired in series.
36-Cell Solar Panel Output Voltage = 36 × 0.58V = 20.88V What is especially confusing, however, is that this 36-cell solar panel will usually have a nominal voltage rating of 12V. Despite the output voltage being 18.56 volts, we still consider this a 12-volt solar panel.
Touch the probes of the meter to bare wire at the end of the cables and you can measure the voltage of the panel. Be careful not to let wires touch each other.
