When your photovoltaic panel hasn't reached the open circuit voltage, it signals potential issues affecting system efficiency. Let's examine the primary culprits: "A 5% voltage drop can lead to 15% energy loss in certain configurations," notes the 2023 NREL Solar Performance. . If a panel has a third less open-circuit voltage, that means a difference of about 11 volts (for panels with 60 cells) or 13 volts (for panels with 72 cells) between strings working normally and those that aren't. This sounds a bit weird, but it's really not. Sometimes they rate at 25 degs C (STC), sometimes at 40 degs C. NOC spec's will have lower panel Voc and Vmp voltages. .

To be more accurate, a typical open circuit voltage of a solar cell is 0.58 volts (at 77°F or 25°C). All the PV cells in all solar panels have the same 0.58V voltage. Because we connect them in series, the total output voltage is the sum of the voltages of individual PV cells. Within the solar panel, the PV cells are wired in series.
Nominal Voltage. This is your typical voltage we put on solar panels; ranging from 12V, 20V, 24V, and 32V solar panels. Open Circuit Voltage (VOC). This is the maximum rated voltage under direct sunlight if the circuit is open (no current running through the wires). Example: A nominal 12V voltage solar panel has an open circuit voltage of 20.88V.
These solar panel voltages include: Nominal Voltage. This is your typical voltage we put on solar panels; ranging from 12V, 20V, 24V, and 32V solar panels. Open Circuit Voltage (VOC). This is the maximum rated voltage under direct sunlight if the circuit is open (no current running through the wires).
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.
