How to calculate solar panel output voltage?
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).
How many volts does a solar panel produce?
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.
What is a typical open circuit voltage of a 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.
How does solar panel temperature affect voltage?
Panel temperature does affect voltage, as discussed in another blog. In the P-V curve, as the solar radiation decreases from 1000W/m2 to 200W/m2, the power drops proportionally – from 300W to 60W. Have a look at these I-V (Current vs Voltage) and P-V (Power vs Voltage) charts for a 305W solar panel from Trina Solar.
How do photovoltaic panels work?
Photovoltaic panels can be wired or connected together in either series or parallel combinations, or both to increase the voltage or current capacity of the solar array. If the array panels are connected together in a series combination, then the voltage increases and if connected together in parallel then the current increases.
Do solar panels produce a higher voltage than nominal voltage?
As we can see, solar panels produce a significantly higher voltage (VOC) than the nominal voltage. The actually solar panel output voltage also changes with the sunlight the solar panels are exposed to.

PV Modules Part 2. Calculations, This Won''t Hurt—Much
First, we find the change in voltage due to the decreased temperature. 68.2 V x 15.9/100 = 10.84 V. Then we add this change in voltage to the original Voc at 25°C. 68.2 V + 10.84 V = 79.04 V. Using Table 690.7, we see that the multiplier factor for -40°C is 1.25 and using this factor gives a Voc of 85.25 volts, a higher, more conservative number.
