Thank you. I need a detail, thus the retrotransposition and the next transposition are performed according to the Hay's model, in according to the following scheme? 1) POA measured ---> GHI and DHI (retrotransposition by Hay's) 2) GHI and DHI -> POA modeled (transposition by Hay's) 3) POA measured is not perfect equal to POA modeled Is it correct? Thank you.

Hi, I would like to figure out how PVsyst performs when POA data values are used as input. Because I found the same POA output values both using Perez and Hay's model, is it a expected result? or should I experience some displacements? Thank you
