Barbadori Posted May 13, 2021 Share Posted May 13, 2021 Hello,I was wondering if there is any report/study about which horizon profile source is more accurate to be imported in PVsyst. I imagine that measuring the horizon on site is the best way to proceed but in the absence of on site measurements, what is the most recommended horizon profile source?The easiest option would be to choose PVGIS horizon from web, that is embedded in PVsyst but I wonder how accurate this source is.Many thanks in advance.

dtarin Posted May 13, 2021 Share Posted May 13, 2021 Another option is meteonorm. The methodologies are similar. They use a digital elevation model and trace back out from the point of interest, calculating the height of the terrain for various azimuths. I think outside of on-site measurement, both are reliable. I have not seen a validation study, however. Link to comment Share on other sites More sharing options...
Barbadori Posted May 14, 2021 Author Share Posted May 14, 2021 Many thanks for the reply.I've read that when using irradiance data measure onsite with pyranometers, the far shading effect is included in that data and it shouldn't be added with the horizon tool on PVsyst. Is that correct?Cheers Link to comment Share on other sites More sharing options...
alihje Posted June 11, 2021 Share Posted June 11, 2021 I actually have the same question. Is it correct that horizon profiles should not be added when using meteo-files including horizon, i.e. measuerd data from a pyranometer? Link to comment Share on other sites More sharing options...
