Open-Circuit Voltage
As the solar panel heats up, the open-circuit voltage decreases. Picture it as a sunbather who feels vibrant in the early summer day but gets lethargic as the sun gets hotter.

It is the time when the solar panel is at its coolest state, resulting in the highest open circuit voltage. To determine the open-circuit voltage (Voc) of the panel, all you need to do is measure the voltage across the positive and negative terminals with a voltmeter.
The efficiency of a solar panel decides the output voltage. If the efficiency is high, more charge will flow in the cells. It means the voltage or potential difference will also be high. If the efficiency is low, you will get a little lower voltage as some of the sunlight won't be able to convert into solar energy. Solar cells have a definite size.

There is also another situation where the affected panel string's open-circuit voltage is the typical 11 or 13 volts too low but none of the bypass diodes are defective; instead, there's an interruption between the junction box and the solar cells.
As the solar panel heats up, the open-circuit voltage decreases. Picture it as a sunbather who feels vibrant in the early summer day but gets lethargic as the sun gets hotter.
The open-circuit voltage, also known as VOC, represents the highest voltage that can be obtained from a solar cell. This voltage is achieved when there is no current flowing through the cell.
