sunlight

i have an enclosed porch with vinyl windows, which is where i keep my beer cooler (bev-air cooler that holds about 300 bottles). i have a guest room in my house that has a closet that is completely dark. on top of my cooler is where i keep my more expensive,rare beers. no direct sunlight ever touches the bottles due to the way the sun rises and sets. i have drank beers from this area and none have seemed to ever be bad. my question is how would indirect sunlight affect the beer? i have gotten some great beers recently in trades (bcbs in particular) and do not plan on drinking them very often, but i definitely do not want to have sunlight ruin them....should i just move them into the closet? i do not have space to get a cellar...and i have them in that spot on top of the cooler for when i have company over as conversation starters (how i got them, what makes them so expensive/good etc) so i do like having them up there. thanks for any input as i am sure this thread title has been discussed at nauseum.

 

Yes there is window tint on it and blinds on both east and west side. The temperature controller is an AC that keeps the room constantly running to keep the room cool. It's not 60 degrees but then again neither is my condo especially during the day when we are work (higher temperature).

 

Lol they aren't all whales. Most in my cooler are just easy to get craft. Sam Adams Sierra Nevada anchor steam. Lots if seasonals. My goal is when someone comes over that says they do not like beer, give them something they can enjoy. I have succeeded in this many times. I wish I knew how to post pictures on here so everyone could see. But in simple I definitely don't need that much beer but I endup buying more than I need of seasonaks that don't stay around too long hence my huge amount. The thing is I have more than that in storage inside the bar...which may be a good spot to out some if my more rare beers.

 

Here is a pic of my cooler from mid February of this year. As you can see there's not really anything special in there but lots if easily accessible craft beers. The rare bottles sit on top. I guess I will start putting bottles away and bust a few out when company comes over as someone alluded earlier.
