Solar panels produce Direct Current (DC) voltage. They can be built to provide nearly any DC voltage. The voltage of the panel is impacted by cell size, cell construction, number of cells, panel size, and panel wiring. The result is panels from 0.5 volts to near 50 volts. Each volt range has a use.
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.
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.
This might sound weird, but both are correct and useful: Nominal 12V voltage is designed based on battery classification. With solar panels, we can charge batteries, and batteries usually have 12V, 24V, or 48V input and output voltage. It is the job of the charge controller to produce a 12V DC current that charges the battery.
