The correct Azimuth in 3d Schene

[Michalis Angeli]

Hello,

I would like to ask something about 3d schene and azimuth of pv panels.

In one project in which i am working this period, I have a house + 2-sided roof.

The plane tilt and azimuth is 25 & 30 degrees, as you can see in first pic1.

Therefore, when I draw the house in 3d shene in order to achive that azimuth i define it -64 degress. (pic2)

Then i draw the panels with tilt 25 degrres and azimuth 30 degrees, like i defined in Orientation window. (pic3)

So, my question is this; The azimuth which pvsyst takes into account to calculate the shadings and production is the 30 degrees that i defined in orientation?

And why the azimuth of house is different than the azimuth of panels, since both "face" the sun position from the same position.

Thank you in adnance.

Sincerely,

Hello, It's difficult to be 100% certain, but it seems to me that in your 3D drawing, the PV plane is not aligned with the roof. Could you please export your project and submit it to support@pvsyst.com for further investigation? Thank you.
