Open circuit 20.88V voltage is the voltage that comes directly from the 36-cell solar panel. When we are asking how many volts do solar panels produce, we usually have this voltage in mind. For maximum power voltage (Vmp), you can read a good explanation of what it is on the PV Education website.
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:
Three primary terms commonly used to describe solar panel voltage characteristics are Voc (open-circuit voltage), Vmp (voltage at maximum power), and Imp (current at maximum power). Voc represents the maximum voltage output of a solar panel when no load is connected, i.e., under open-circuit conditions.
Typically, a 100-watt solar panel produces about 5.55Amps/18 volts of maximum power voltage. The voltage that solar panels produce when they produce electricity varies according to the number of cells and the amount of sunlight that they receive. How Many Volts Does a 200W Solar Panel Produce?
36-Cell Solar Panel Output Voltage = 36 × 0.58V = 20.88V What is especially confusing, however, is that this 36-cell solar panel will usually have a nominal voltage rating of 12V. Despite the output voltage being 18.56 volts, we still consider this a 12-volt solar panel.
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.
