Use different feedin ts for pv_ground_vertical_bifacial

[nesnoj]

Currently we use sequences/solar-pv_ground_profile from oemof datapackage for all PV ground. However, a different timeseries for pv_ground_vertical_bifacial needs to be integrated (for pv_ground_elevated the existing solar-pv_ground_profile is ok).

@henhuy
Do we need separate components for PV ground in the esys or can we overlay both timeseries on-the-fly (weighted)?

[henhuy]

Don't know if I fully understand the question.
For django-oemof it is no problem to update profiles on runtime, BUT as we want to use TSAM aggregated timeseries, timeseries have to be aggregated and stored in DP beforehand.
We could have multiple DPs prepared and select DP for simulation depending on user settings, if this helps?
Don't know how many DPs we need in this case?!

I see, so the only option seems to be adding separate pv_ground_... components incl. profiles to the esys.
Which would require adjusting the mapping between backend and sim

You are right - but this would be a small change IMO (one extra line or something).
As you can see #117 I have to revisit EE calculation anyway.
But @srhbrnds has to rerun TSAM for us as well.
