How about this scenario; consider my shed as very long shed and ignoring the reflection from tow side of the table 3,4. see attached image.
and regarding the pitch I use respectfully high value ( let say 10m ), so system read maximum value of irradiance reflection from both sides 1 and 2 towards panels backside.
Would this works? so I could simply use Unlimited Sheds field type and avoid making 3D and no need for reset error message.
What do you think?
