I need to analyze for the panels to be installed on the facade of the building .(Not rooftop) But, what steps need to be followed for the facade of the building. When I select Tilt 90 degrees and try to analyze it, the PVsyst system is locked. Do I need to choose a different option?

Hello Andre; I did two analyzes at the same location, same bifacial panels with the tracker system. Only the inverter was different. However; There are 2 different Global irradiation and sky-diffuse on rear side values in the analysis. Why the Global irradiation and sky-diffuse values are different? Thanks.
