Need help in setting up portable solar power panel?

I have a small solar panel I use to charge up my batteries for my bait boat for fishing. I like to keep it connected so it is always fully charged up. As we have been having sunshine and showers of late I don’t want to risk leaving it outside while I’m away from home. Will it still work if I prop it up in the double glazed kitchen window which faces south? Please help.
