If the panel has 72 solar cells in series and each cell has a voltage of 0.6V, the theoretical Voc is 43V. Here's a simple table that takes you through the different types of voltages for different wattage solar panels: 30V for a 60-cell panel with 0.5V solar cell output. 36V for a 72-cell panel with 0.5V solar cell output.
If you know the number of PV cells in a solar panel, you can, by using 0.58V per PV cell voltage, calculate the total solar panel output voltage for a 36-cell panel, for example. You only need to sum up all the voltages of the individual photovoltaic cells (since they are wired in series, instead of wires in parallel). Here is this calculation:
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.
Example: A nominal 12V voltage solar panel has an open circuit voltage of 20.88V. This sounds a bit weird, but it's really not. Voltage output directly from solar panels can be significantly higher than the voltage from the controller to the battery. Maximum Power Voltage (Vmp).
A single solar cell has a voltage of about 0.5 to 0.6 volts, while a typical solar panel (such as a module with 60 cells) has a voltage of about 30 to 40 volts.
