For any specific day during 24 hour, it is not possible that on a horizontal surface direct radiation be less than diffuse radiation. Especially when we have 270 sunny days in a year. I talked with two professor about these results. both of them said results are wrong.
in the 6th july sky is so sunny but diffuse radiation on a horizontal surface is more than direct, this is impossible and so wrong unfortunately.
one time, i set “true” (remove diffuse) and i sum values and gained total direct
another times, i set “true” (remove direct) and i sum values and gained total diffuse
and finally i compared them.
i guess ladybug calculate direct radiation instead of diffuse radiation and conversely
