Default Sunlight and beer

Ok ive got my beer primary fermenting in a closet, the only problem its the same closet as all my clothes, and about 3 different times this week ive been in a hurry in the morning and left my closet doors open, exposing it to westward facing sun during the day.
Ive relaxed and had my home brew ( i still have a few from the last batch), and Ive got solar screens on those window and blinds and some sheer curtains on the inside, but light does still get into the room.
How worried should I be?

It'll be fine. Throw a black t-shirt over it and wait for the yeasties to finish their snack.

Not at all, It requires direct sunlight to effect the beer. The hops in beer is very sensitive to UV rays and will under a chemical change in effect causing it to become "skunky".

Glass doesn't pass a lot of the deep UV spectrum, so don't worry. You'd need to expose it through glass for a long time for any skunking to happen.

Note to self: I need to do an experiment on this soon.
