Mismatch Calculation Using Graphical Tool

[Mubeen A S]

Hi,

I am trying to do a mismatch analysis using the flash test data in PVSyst Graphical tool. I want to understand why PVSyst is considering Isc and Voc values a input parameters, instead of Impp and Vmpp. 

As per my flash test data, RMS value of Impp and Vmpp is comparatively higher than Isc and Voc respectively. Therefore, I am not feeling very confident after seeing a very low mismatch loss, after considering Isc and Voc values.

 

Request you to explain this.
