Backtracking settings for NS tracking with Azimuth different to 0deg

[Andrew]

Hi, 

I have a N-S tracker, with an azimuth of 15deg. Is it possible to accurately model backtracking with this azimuth by defining the azimuth in the shading object setting?

When I try this method I am getting high electrical losses...

I saw a post from 2016 indicating this needs to rather be modelled with a 0deg azimuth, with the shading scene then rotated by 15deg.

When I try this method the impact to the in-plane irradiation is minimal, which surprised me.

What is the current recommended approach, and are there any shortfalls to watch out for?

Cheers,

Andrew

Hi, this is surprising. As far as the latest version goes, the backtracking works with axis azimuths different from 0°. Are you using the latest version or a previous version?
