VOC Corrected by Irradiance and temperature

[Ava]

When the Voc is corrected by irradiance and temperature, whether the corrected Voc is affected by the number of cells?During the calculation, I found that the number of cells did not seem to be corrected for 66, but by 72.

The number of cells is defined on the page "Size and technology".

In your case, the Vmpp = 39.27 V  at STC, indeed corresponding to 66 cells, i.e. a voltage of 0.595 V/cell, which is quite correct.

Now when you are using the model under  different  irradiance and temperature, the Voc is obviously different (here higher than at STC as the temperature is lower then 25°C).
