RE: [EnergyPlus_Support] Surface Heat Balance of Decoupled PV
Hello,
Yes, shading effects are considered. The incident solar will be reduced if other surfaces in the model will shade the PV panels.
If by "decoupled" you mean you are using the object "Surface:HeatTransfer:ExteriorNaturalVentedCavity" then the model assumes that none of the solar will make it to the underlying surface, it is all incident on the decoupled surface (baffle) that has the panels.
No, you do not include the PV panel in the construction of the base surface. (But if you were modeling PV as "integrated", then you would include it in the construction, but you would use a "Construction With Internal Source" object.)

Subject: [EnergyPlus_Support] Surface Heat Balance of Decoupled PV
Dear all,
For the case of decoupled PV, does the surface heat balance consider the shading effect
by the PV panels? If a PV is input as decoupled, do we need to include it in the construction
of the base surface?
Thank you!
