Hi, I am trying to do a simulation with PVsyst, and the simulation has the following inputs: It's two seperate buildings with sadel roof for both, and the inclination is 3˚ degrees, the roof material is bitumen, Since the roof has 3˚ tilt and it is bitumen, the best mounting system would be ballast with 10˚. So if we have the module on both sides of the roof, the module field on the front side of the building would have 13˚ tilt angel relative horizion. While the module field on the back side of the building would have 7˚ tilt angel relative horizion. (The roof is inclined backwards from the horrizion with -3˚ degrees, so the moudle subarray would have a total inclination angel of (10˚-3˚=7˚) Now, since one of the buildings has an Azimuth of +2˚ and the other one has -3˚, this would leave us with 4 different orientaitons. Orientation 1: -3˚ with 13˚ inclination for the front side of the first building Orientaiton 2: -3˚ with 7˚ inclination for the back side of the first building Orientation 3: +2˚ with 13˚ inclination for the front side of the second buildning Orientation 4: +2˚ with 7˚ inclination for the back side of the second building When trying to configure the panels after being done with the shading scinario, seems like the program is translating the orientation 2 and orientation 4 as single orientation with an Azimuth of -1,3˚. P.S. When we do the same simulation but we choose a 10˚ degree tilt angel for the back side of each roof, the simulation works fine, and no mixing between the module fields would happen. I could attach the simulation project as well if needed. Thanks for your help.
