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.

A 24V solar panel typically has an open-circuit voltage (Voc) of approximately 46V. After learning this, let's also try to find out what is the Voc on a 100 Watt solar panel.
