System with 4 different orientations and mismatch between shading scens and system orientation window.

[Usama Alfadel]

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.

Hi,

Try to identify orientation with smaller tolerance.

Also, you can create manually your 4 orientations and attach fields to each of them:

If you still cannot get it, try making each distinct orientation a separate group in the shade scene, then try the method stephane has stated.
