RMS - receiving different mismatch losses with same inputs

[Mara]

Hey all, 

I noticed that when I use the detailed computation of PV Syst to get the module mismatch loss at MPP, the results changes when re-doing the detailed computation (within minutes) even though nothing of the parameter/project has changed:

 

WHY?

 

Kind regards, 

Mara

Hi this tool uses monte carlo for the evaluation.
Basically random trials are done every time. The values will only converge with many trials.
