I know this post is quite old now, but I picked up one of these last November as a black thursday gift to myself. It's an easy entry into solar energy, but all in all, you can do much better.
At the time I ought it, $5 watt for solar was a standard price, but cost have long since dropped. That makes this kit expensive and not nearlly a good value.
The frame is pretty weak. You must secure it to a surface or else it will fall apart. It only holds on to the panels with a steel lip across the bottom. It's also unadjustable. When I bought mine, I considered it a free extra, but compared to current costs, I can't do that anymore.
The "Charge Controller" is little more than a few voltage switches and an automotive style socket. While it does provide all expected safety features, if you put in more than one kit worth of solar, even a small good charge controller will make up it's cost in energy savings. It does have some alternative power outputs, including a usb connector, but the step downs on these seem to use up a lot of power. They drop the voltage quickly.
Finally, I never used the CFLs. They were a cold institutional blue color, and after 5 minutes, they had to go. There are numerous alternatives to use.
