Solar is disappointingly expensive

After a little research I have come to the same conclusion that thousands before me already had: Solar is expensive!

First the good stuff:
I bought a 6.5W foldable solar panel from Frys a few days ago. It has extremely little to set up - all you need to do is find some sun and plug in your device.
Thanks to the innumerable "road warriors" out there, almost all electronic devices that need charging come with a car charger. As a result, the most important connector provided with this foldable panel was the the car charger (female).

I connected my battery charger to the solar panel - this is a reasonably good way to charge up my AA and AAA cells, without being on the grid and without draining the car battery. I could also charge my Nokia toys in this way as well.

After that I started checking out what else can be put onto this foldable panel. The rated output is 6.5W. With a 12V rated voltage on the car connector, it means that the rated current is a measly 0.54A.

The typical Dell laptop needs 19V,4.6A at its input DC.
For me to use this panel for the laptop, I would have to make a series-parallel combination to achieve that sort of a rating. I'd need 10 branches in parallel with 2 panels in each branch to make it 24V, 5.4A - With this sort of rating, I may be able to use one laptop off it.

However, the cost comes in the way: Per 6.5W panel comes at $100 in Frys. Pricegrabber shouws lowest price at $74, but even with that, the total price for running one laptop off solar panels is $2000. Way too high.

What about higher rated solar panels? The manufacturers usually can cut costs for larger panels, why not go for that?

A 100W solar panel from ICP seems like a good choice - except for the fact that it costs $800 +.
I can definitely come up with that sort of money, but how much sunlight will I have to eat to break even on the investment?

I'll get the numbers as soon as I can and see if its a worthy investment.
