For any journeyman electrician or master electrician working with photovoltaics, correctly performing a wire size computation is essential to prevent significant. . Voltage drop in solar systems is the reduction in electrical voltage that occurs as current flows through conductors due to resistance, typically measured as a percentage of the total system voltage. For instance, consider the following specifications for a solar panel: VOC (open-circuit voltage) is 22. 3V, ISC. . The VOC is the Open Circuit Voltage – is your solar panel or a solar array is producing too many volts? If so, there is a simple way to reduce the number of volts that a solar panel sends down the circuit. This voltage increases from the rated voltage as the temperature drops below 25°C.
