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.
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.
Solar panels produce volts when exposed to the sun. But, that is only part of the equation. Panels also produce amps. In most cases, panels are rated in watts. Watts are the result of the number of volts multiplied by the number of amps. Solar panels are rated by the work they can do measured in watts.
Nominal voltage is an approximate solar panel voltage that can help you match equipment. The voltage is usually based on the nominal voltages of appliances connected to the solar panel, including but not limited to inverters, batteries, charge controllers, loads, and other solar panels.
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.
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:
Ultimate Guide to Solar Panel Voltage
Solar panels have multiple voltages associated with them, including voltage at open circuit, voltage at maximum power, nominal voltage, temperature corrected VOC, and temperature coefficient of voltage. The open circuit voltage generally lies between 21.7V to 43.2V. The maximum power voltage usually lies between 18V to 36V.
