Hello Mostapha !
thanks for the warm welcome !!
Yes exactly, i would like to be able , to generate the sun vectors, because the european norms is asking to calculate the solar factor from specific specific angles and not specific hours.
I actually don’t know what is the logic of usin angles that doesnt not always exist in a specific location and what would be the effect on the skyparameters ?..
I’ll add my picture as soon as possible
