Validity of Sunlight Hours

Hi,
I try using ladybug for “sunlight Hours” analyze, but I have doubts about the results because it is very Low and even when I scaled the target surface 10 times bigger, the results still very low and I don’t know if I do it right or where did I make a mistake, so If anyone can check my algorithm, please.
I Upload the ‘EPW’ and ‘GH’ file. thanks.
