How to calculate solar panel output voltage?

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:

What is the voltage output of a solar panel?

In solar photovoltaic (PV) systems, the voltage output of the PV panels typically falls in the range of 12 to 24 volts. However, the total voltage output of the solar panel array can vary based on the number of modules connected in series.
