No solar gains through window?

Hi all!

I was wondering why a change of the SHGC-value doesn’t really affect the results. So I checked the total solar heat gains. There are no gains through all the year (picture is in summertime):

I already tried different epw-files.

Thank you very much for your help!

All the best

Problem solved by itself. It didn’t recognize the windows as windows.
I just disabled and enabled all the components three times or so. Then it worked. Whatever.
