Open-Circuit Voltage in Solar Panels

In solar panels, open-circuit voltage (VOC) is a key parameter that affects the efficiency and performance of the system. VOC refers to the maximum voltage that can be generated by a solar panel when no current is drawn from it. It is an important indicator of the panel's potential to convert sunlight into electrical energy.

VOC is influenced by several factors, including the type of solar cells used, the temperature of the panel, and the intensity and spectrum of sunlight. Under ideal conditions, a solar panel with a higher VOC can generate more power and operate more efficiently.
