Solar Battery Charger for Enclosed Trailer

Anyone using a solar panel charger / battery maintainer for their enclosed trailer? I was thinking a 5-watt panel would be enough to keep the battery fairly well maintained. I just use if for lighting when the trailer is not hooked up to the truck. I may slap a stereo in there at some point. I have two 15 or 18-watt panels on my camper that seem to do the trick all summer. So I figured a 15-watt panel would be over kill. Any thoughts?

@weijing3333,
I don't have such a trailer, but even 15 watts sounds kind of puny. Unless the costs are way higher than I think, I would leave a good bit of headroom. Maybe farmerman will check in. I think he has real experience on this.

@roger,
I use 2 15 watt units on our RV (it keeps the batteries charged on the roads if we arent using a draw (then we use a generator)
My wife has 2 units on her box trailer for her craft shows. She has seberal tools that are 24 v cordless. and the trailer battery is nice and "topped up"

They recc one 15 W solr pnel but two cant hurt for our area of the world. (Sometimes, in New ENgland we wont get full sun for days and we have to keep the generator fired up (The gennies now have a computer that senses when you are running low and it kicks on or off -like if we use the nuke and have the tv and some appliances on)
