Dear LenLor ,
I have the same issue . the simulation with Energy Plus do not take in consideration the thermal effect .it only consider th benefit of shading . I wanted to evaluate the impact of PV Panels On roof .
I have used PV panels from Ladybug as an HB context before running the simulation on energyplus . and the simulation donot consider the overheat caused by PV panels .
I invite you to see more details on my post :
Hb Context -Pv panel
