orientation

Hi, 

I would expect the orientation to be "the same" on the south and the north side of a roof I am making calculations on.
Using a "east-west" system divided on south and north side of the same roof, in this example i get following orientation.

North Building:
  50% are 115° South-east + 50% at 307° North-west

South Building:
   50% are 127° South-east + 50% at 295° North-west

I would expect the orientation to be either 115°/295° or 127°/307° and not the mix of 115°/307° and 127°/295° that have been used in this simulation.

Why is this?

Best regards

Daniel

Hi Daniel,

it looks like your roof has a ridge that is not exactly in North-South direction, is that correct? In that case, if you have a small inclination of the roof surface and you mount a PV system with its own orientation and tilt, the resulting orientation and tilt (or inclination) will be different. For that reason there is also a small dialog in the mounting system dialog that explains this a bit:

Hope that helps, kind regards,
