How many volts does the DC power of a solar panel have

The typical voltage output of a solar panel ranges from 18 to 45 volts DC, depending on several factors. Most commonly used panels have either 60 or 72 cells. Panels with 60 cells usually produce around 30-36 volts, while those with 72 cells generally output upwards of 40 volts. This is the maximum rated voltage under direct sunlight if the circuit is open (no current running through the wires). Monocrystalline panels tend to produce higher voltages. . While nominal voltage is the standardized voltage that's used to classify solar panels (usually, 12V, 24V, or 48V), the actual operating voltage of a solar panel is different.
