That surface defines the position and geometry for all the PV models, but the net area of that surface is only used with the Simple model. Net area is the gross area minus the area of any sub-surfaces ?see I/O Ref entry for the fielld called â??Fraction of Surface Area with Active Solar Cells. The more advanced PV models use the area of the PV module entered in the respective PhotovoltaicPerform ance input objects and donâ??t use the surfaceâ??s area at all.

Subject: [EnergyPlus_ Support] "Surface Name" in Generator:Photovolt aic
Hi everybody,
I have a question about photovoltaic model on EnergyPlus.
I want to simulate a building with PV panels located in the building façade.
In the object "Generator:Photovol taic", I have defined the "Surface Name" where the PV array will be located as being the external walls of the building.
If there are windows on these walls, I don't know if the program will automatically desconsider the area of the windows, to locate the PV panels, or I have to create another surface on the opaque surfaces in order to locate the panels?
Thank you very much,
Paulo Ara.
