Dear all, I was researching vertical panel simulations. I'm simulating a system with 43,6 kWp, bifacial panels, E/W orientation, tilt 90°. Bifacial configuration include the option "Use unlimited sheds 2D models". Distance between panels (pitch) and Height above are design specifications. Shed width is based in height of panels. The albedo was selected according to PVsyst tables that relate soil type. Image 1 as reference My specific question is about the results, since the "losses array" returned a negative value (indicating a supposed gain? which doesn't make sense) which is not expected. Can you tell me what this means? Or possible causes for this supposed error? image 2 as reference. Thank you in advance for your attention, I look forward to hearing from you. Sincerely, Eduardo.

Dear Edwin Tellez, you will need to change the simulation. Separate the different configurations as project variants. PVSyst is unable to simulate because the panel arrangements are too physically different. The "unlimeted sheds" option requires homogeneous distribution of the photovoltaic plant as it is a limited resource so far.
