Solar USB charger schematic?

I need a solar usb charger schematic and a list of things I need.

Check the technology section of the site. There are USB solar charger projects on every other page. Update the tags for this post to include solar and charger and you'll get a list of related projects on the right hand side of this page.

BTW there are 2 fetured projects posted on the main page of the site conserning this.
