Weird results , ladybug total radiation

Hi everyone,
I run radiation analysis on ladybug but i have weird results. First of all i run 2 radiation analysis with epw for Athens. One from 1/5 to 31/9 (heating season) & one for 1/10-31/4(cooling season) both from 8 am to 19 pm. The final results are 3230.39 kwh total for heating season & 4996.63 kwh for cooling season.
Any suggestions ?

Hi Raphael,

Can you provide some more background? Where is your analysis plane? Is there shading?
