If I place it inside it's doable to some extent. I made lukewarm water from tap temperature in 1L tin can (spraypainted black) behind the window. With concentrated rays it can be made warmer. But I dunno how the keg would fare.
Insulated box with glass panel could also work. I think.
Could be combined with beer-collector.
