Change in far shading losses going to version 7.3

[laurahin]

We have compared the results of several simulations using 7.2.21 and 7.3.1/7.3.2.  In all cases, the far shading loss is lower in the 7.3 versions, in one case by 30% (i.e., 1.23% goes to 0.94%).  There can also be much smaller increases in the near shading loss.  Is this an intentional change, and if so, what is the reasoning?

Thanks!

Hi Laura,
Thanks for the feedback, we'll be looking into the issue, it was not a bug known to us yet.

Has there been any confirmation of or resolution to this issue?  Thanks.

Is this addressed in the 7.3.3 update?

The horizon model has been improved in 7.3.3 and it should also cover the bug we mentioned.

The results may still differ a little from 7.2.21 but this is due to the improvement:
we now consider more correctly, within each hour, the fraction of the sun trajectory that is behind the horizon. Please let us know if you experience anything strange agin.
