I have an OpenStudio house model and I have added the measure "Add Rooftop PV" from BLC measures.

This what I'm trying to do is to find out how could I export the DC output from the PVs in an CSV file (I already used for Ideal Loads Cooling/Heating and exported all these to CSV files) but I don't know what is the correct variable name to copy from the eplusout.rdd file.

I want only the DC output from solar panels in CSV every hour, it would be better the values to be before the inverter. Is it possible?

I'm attaching my .rdd file here:

Thank you in advance!

I believe the BCL "Add Rooftop PV" measure adds a Generator:Photovoltaic with a 'simple' performance type. From the .rdd you have provided and from the energyplus input output reference for this object's outputs, the 'Generator Produced DC Electric Power' and 'Generator Produced DC Electric Energy' would give you what you are looking for. You would request this from Openstudio by including these Output:Variable objects in your model. Hope this helps!
