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. . This is the maximum rated voltage under direct sunlight if the circuit is open (no current running through the wires). This sounds a bit weird, but it's really not. Voltage output directly from solar panels can be. . A higher open circuit voltage generally indicates that the panel has a higher potential to produce power, while a lower open circuit voltage means the panel has a lower potential. Here's a fun way to understand it – imagine a water tank with a tap at the bottom. It could be anywhere between 21.
