Open Circuit Voltage or VOC is shown in the panel specifications and is the voltage available from the solar panel when there is no load attached and the circuit is incomplete, so no current is flowing, hence the name Open-Circuit. When a load is attached to the circuit it becomes complete and current flows.
When multiple solar panels are connected in series, their open-circuit voltages are added. The Voc plays a crucial role when determining the maximum number of solar panels that can be connected to your inverter or charge controller without overloading them.
The open-circuit voltage (Voc) can be obtained by simply measuring the voltage across the positive and negative terminals of the panel using a voltmeter. It’s important to remember that Voc represents the maximum voltage a solar panel can produce under standard test conditions.
Two such key specifications are Open-Circuit Voltage and Short-Circuit Current. What is open-circuit voltage? It is the voltage the solar panel outputs when there is no load connected to it. The open-circuit voltage (Voc) can be obtained by simply measuring the voltage across the positive and negative terminals of the panel using a voltmeter.
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.
There are several terms associated with a solar panel and their ratings such as nominal voltage, the voltage at open circuit (Voc), the voltage at maximum power point (Vmp), open circuit current (Isc), current at maximum power (Imp), etc. All these parameters are crucial to know before purchasing or installation of solar panels.
