Horizon included in TMY PVGIS 5.1/5.2 .SIT

[ManPC]

Hi

I would like to know if the terrain shadows (far shading losses) are included in the TMY PVGIS 5.1/5.2 imported data when a .SIT is created.

Thank you.

Unless someone here has already reached out to PVGIS and received an answer for this question, my guess would be no. Most (all?) satellite TMY data will not. Ground measured data can take horizon into account.  PVGIS has a separate tool for determining horizon losses. They are pretty responsive (at least in my prior experience), give them a shout.

Hi,

The TMY PVGIS file doesnt' take the horizon into account. 

For this, you must use the "horizon" tab of PVsyst to take into account the far shading.
