[retrotransposition model]

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.

[retrotransposition model]

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
