Hi forum,
so I searched for a way to use my meteo data of direct and diffuse irradiation (only GHI). I did not find any possibility for that, please correct me if I missed something.
This means I would need to use a standard model and lose a lot of accuracy when using PV*SOL with accurate irradiance (dir/diff) data from sources like SolarGIS e.g.
When comparing results in my example to pvsyst the yearly irradiance on the tilt plane (25°) is lower by 6% (due to wrong ratio (dir/diff)).
How is it not possible to set those crucial values or did I just not find the right option?
