Irradiance inputs for PV Plant

Dear all,


For a PV project, I was wondering which variables to use as GHI, DHI and DNI from ERA5 hourly data on single levels.

I read on the forum that "surface_solar_radiation_downwards" is suitable as GHI (and some comparisons with other database and different location seems to confirm that assumption) but for DHI or DNI, I'm not able to find a suitable variable.


Thank you very much in advance

Hi Florian,

In our paper we used the ERA Interim dataset to model the PV performance. More details here:
