hi all
in the below pic, if i set ‘true’ diffuse radiation, my results is direct radiation on my geometry? my geometry is a semi-sphere!
i don’t know why annual diffuse is more than direct radiation?!! it is so strange! EPW… LONDON
Did you try to draw a radiation rose and compare the contribution of diffuse versus direct radiation?

dear Mostapha
actually, i have a semi-sphere and i gonna calculate how much radiation will be received by my geometry in a year, then i gonna compare annual diffuse radiation and annual beam radiation in a year period.
