Direct sun hours for indoor study not showing hours

I want to calculate glare potential through ‘direct solar hours’ indoors (according to different window shades)
I’m simulating the floor surface (could be wrong) with the walls etc as context but it shows dark.

What could be going wrong here?

You are probably including the windows geometry in the simulation. For SunHours analysis they are considered opaque. The material definition doesn’t apply.
Try excluding them.

Thank you, I removed the apertures, but it still is dark. Also, I want to see the effects of the shades on direct sun hours. Is there a better way to do it?
