I would like to power my laptop with the sun.

I'd like to work from home while on the road.....
I have an IBM X41 tablet and plan on keeping it for a few more years.
I just purchased a converted Econoline van that is perfect for kiteboarding, which I want to do lots of this summer.
It's also ideal for working, as long as I have a cellular connection for my wireless card and for my phone. My work depends on online access and phone access.
My van has an inverter and a second battery (marine deep cycle). They are both fed energy from the stock alternator. I'd like to use it as little as possible, as I have other energy needs.
My laptop uses a 16V DC input from its power adapter. It says it uses 3.5 A.
I'd like to camp out at kiteboard spots and work from there, however the bottleneck I experience is getting power to my laptop and possibly phone (though I have a long-range phone battery and can purchase another).
I'd like to find a way to power my laptop (actually its battery) while I'm working without draining my van's battery. The ideal solution would be one with a solar panel on the roof directly charging the laptop's battery. I searched the net and didn't find anything that seems suited for this purpose.
Another idea is to wire a voltage converter to the extra battery to step it up from 12V to 16V and bypass the inefficient inverter.
Does anyone have any experience with any of this?
