array mismatch losses

[inyss]

 Hello !

I would ask about the definition of mismatch loss which says : 

The mismatch loss is defined as the difference between the sum of all Pmpp of each independent sub-module, and the Pmpp of the resulting I/V characteristics of the array.

is the result of this formula is this one shown on losses diagram

Mismatch loss is not calculated, it is entered by the user under detailed losses menu. Mismatch due to differences in IV characteristics is relatively low, but it is one contribution to mismatch losses; temperature and irradiance differences also contribute to mismatch losses.

thank you dtarin ! 

I were a litle bit wrong ! yes it is an input parameter which must be seted between 1%-2%
