I'm a big solar advocate BUT:
If you have an onboard charger and you aren't away from shore power more than a weekend, I would consider solar panels a waste of money. Figure out what your power requirements are, and install enough batteries to handle the load for say 4 days (to be safe). Then a good charger to charge them up during the week.
You can buy a whole lot of batteries (and a charger) for the price of one good solar panel. You're going to need the batteries anyway, so you can install them first and then look into solar panels and controllers later, IF you still want them.
Until you can come up with a good estimate of your load, everything else is a waste of time.
