Out Door Solar Lights

I have been looking for outdoor lights for my patio ever since Alan and I moved to this apartment, approximately 6 months ago. My little patio needs lights, hanging lights (sort of like Xmas lights), because at night it is really dark in Mountain View. There is no power outlet in my little patio. Therefore, I have been looking for solar lights. There are none. None in the world. The only outdoor solar lights for sale are those that you stick in the ground, not hang.  It seems like a fairly straight forward concept. Why are there none? I'm sure the technology exists. I'm sure people would buy them if they were for sale.

Can you imagine how much electricity would be saved if people used outdoor Christmas lights that were solar? There is a whole untapped market waiting to be exploited. But aside from all the money that could be made, I'm just annoyed that my patio continues to be too dark to hang out in past 4:45 in the winter. Really, its just silly that I can't find any.

I mean hanging solar lights that work. I got some for Xmas, and they don't work. :(
