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.
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.
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. What gives? Which is the correct voltage; 12V or 20.88V?
Whether it be open circuit voltage, maximum power voltage, or nominal voltage, you will find it all in the datasheet of the manufacturer. Generally, the nominal voltage of any solar panel is 12V or 24V. This is the voltage at which normally DC appliances operate, batteries are charged, etc. However, the nominal voltage could be 20V or 18V as well.
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).
Monocrystalline panels, known for their high efficiency, typically have voltages between 36 and 40 volts. Polycrystalline panels, while slightly less efficient, also fall within the 36 to 40 volts range. Thin-film panels, which are lighter and flexible but less efficient, typically generate voltages from 20 to 30 volts.
