He may not have a fridge, which is a somewhat constant load, but a stereo and inverter suck a heck of a lot more power than my fridge....
So he still should consider more Input or more storage, depending upon his needs.

Below are links to solar panels I just put on my new to me motor home and also put one of them on Karl Ws Westy roof while out in Pheonix, <http://frankcondelli.com/travels/?p=984>   These 100w panels are cheap and work so well you will be surprised.  I have a 130w Kyocera panel on my Westy that's been there for several years now, paid something like $1000 for the whole set-up, panel, Morningside controller, connectors and wiring, enough to install and make up three 33' foot extensions.  The new panels I just got out-perform this old panel by far, at first light the panel is putting out power, not so with my old Kyocera.  Solar panel technology has come a long way and it's not over yet !  My advice, get the biggest panel you can afford, bigger is better, even if you "think" you don't need it YOU DO !  Remember these things produce electricity with the sun and the sun is unreliable !  Plus the angle of the sun on your panel is not going to always be optimum so BIGGER is better.
