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.
In summary, the output power of the solar photovoltaic panel needs to be adjusted to the orientation of the solar photovoltaic panel, and the light intensity tracking technology is used to ensure that the solar panel maintains maximum efficiency in one day.
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).
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.
According to the simulation of sunshine changes light intensity can enhance the output power of within one day, the simulation shows the influence of photovoltaic panels. In order to obtain more illumination, sunshine on the output power of photovoltaic power it is necessary to set the photovoltaic panels. Automatic generation.
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.
