Questions related to Window emission and sun light

Guys, I subscribed to your service to learn how to use Blender. I tried to recreate the room with just two windows. I tried using the emission material for the windows, but the problem is that the sun rays don't pass through. If I change the material to transparent, it works. If I load your initial model, you used the same emission material, but it works for you. What am I doing wrong?

Thanks ;)
