So am I right in assuming that the shading losses that we get when using backtracking (2.5%) are only due to the diffuse component of the solar irradiation?
If not employing backtracking, I assume it is required to define either "Linear shading loss" or "According to module strings" to account for shading losses for beam (and diffuse) irradiation (around 10%?). Would there be any reason why one should not account for these shading losses when not using backtracking (considering angles of +-60 degrees for example)? I have come accross a couple of consultants doing this...
Backtracking "Lineal shading" or "According to module strings"

Hi all,

Thanks for your time and consideration.
