The Voc or "Open Circuit Voltage" is the maximum voltage that a Solar PV panel can output. This parameter is very important when designing a system because it can be used as an indicator of what each panel can contribute to the voltage of the string. For strings wired in series, the Voc multiplies per panel.

Solar panel Voc, or open circuit voltage, is an important parameter to consider when evaluating the performance of solar panel s. It refers to the maximum voltage that a solar panel can produce when it is not connected to any load. In other words, it is the voltage output of the solar panel when the current is zero.
Open circuit voltage (OCV) refers to the voltage that a solar panel produces when it is not connected to any load or circuit. In other words, it is the voltage that is generated by the solar panel when there is no current flowing through it. The OCV is measured in volts and represents the maximum amount of voltage that the solar panel can produce.
The open-circuit voltage, V OC, is the maximum voltage available from a solar cell, and this occurs at zero current. The open-circuit voltage corresponds to the amount of forward bias on the solar cell due to the bias of the solar cell junction with the light-generated current. The open-circuit voltage is shown on the IV curve below.
Open Circuit Voltage (Voc) The voltage of the open circuit is how many volts the outputs of the solar panel are without load. If you only measure the positive and negative terminals with a voltmeter, you’ll read Voc. Since there is no connection between the solar panel and anything, there is no load on it and no current is produced.
