The voltage of a solar panel is the result of individual solar cell voltage, the number of those cells, and how the cells are connected within the panel. Every cell and panel has two voltage ratings. The Voc is the amount of voltage the device can produce with no load at 25º C.
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:
Think of voltage as the pressure in a water pipe; the higher the pressure, the more water flows through the pipe. In the context of solar panels, voltage is crucial because it determines how much potential energy the panel can generate. Different solar panels have varying voltage ratings, typically ranging from 12V to 48V.
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.
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.
Understanding wattage is essential for determining how much energy a solar panel can produce and, consequently, how much power your devices or appliances can draw from it. For example, a solar panel with a voltage of 20V and an amperage of 5A has a wattage of 100W. This means the panel can produce 100 watts of power under optimal conditions.
