Mobile Solar LED marquee

I've got a feasibility question for the forum.

I'm interested in prototyping an outdoor solar-powered LED marquee-display drawing messages from a modem/SIM card (and therefore updatable via SMS).

The modem piece of this is certainly possible, I think I could whip this together with an arduino board if necessary.  The solar piece is questionable, given the voltage requirements of even a small LED display + modem + controller.

Would love to hear people's thoughts on where to start with this.  I'm considering using the LED marquee instructable, or even creating the dot-matrix myself.  There are also hundreds of display manufacturers, so it seems like tinkering with a 12V display might be the fastest solution.  In terms of solar powered displays, however, I've found only one company doing this, and the costs are enormous.  

Thanks for reading.

Look here for the guy with the LED shirt. It's wearable with portable power so you might get some ideas.  Good luck.
I'm interested in such a sign for my business. Please let me know if you know of any available.
