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..

The open-circuit voltage, Voc, is the highest voltage a solar panel can reach without a load. This ranges from 21-33V for a 12V panel..
For a 12 Volt panel the open-circuit voltage will be around 22 Volts – or a volt or so either way..
The open circuit voltage generally lies between 21.7V to 43.2V. The maximum power voltage usually lies between 18V to 36V. The nominal voltage varies, but the general values are 12V, 18V, 20V, or 24V. [pdf]
An model of an ideal solar cell's p–n junction uses an ideal (whose photogenerated current increases with light intensity) in parallel with a (whose current represents losses). To account for , a resistance and a series resistance are added as . The resulting output current equals the photogenerated curr. To calculate the open circuit voltage (Voc) of a solar cell, you can use the following formula: Voc = Vt × ln ( (Isc + I0)/I0) Where: Vt is the thermal voltage, which can be calculated as Vt = k . .
To calculate the open circuit voltage (Voc) of a solar cell, you can use the following formula: Voc = Vt × ln ( (Isc + I0)/I0) Where: Vt is the thermal voltage, which can be calculated as Vt = k . .
Here is the resulting formula: VOC = (n × k × T × ln (IL/I0 + 1)) / q As we can see from this equation, the open circuit voltage of a solar PV cell depends on: [pdf]
