SOLAR is the new GREEN thing these days, and California is a great place to utilize this technology!
I made a cool portable USB solar charger, using two 6v polycrystalline solar panels (the most efficient type), with a 12v car USB charger adapter (both available on eBay – Links below). The solar panels were about $12 each, and the USB car adapter was only about $3. I also bought a 12-foot cigarette lighter extension cord for $3 at Big Lots, that I cut in half, then used half so I can plug in my solar panel to my car, and have the other half to use with this setup, if necessary. The AA battery backup charger was only about $20, and provides an extra boost at night, on-the-go, or when there’s no sun. It’s always charging when under the sun, but charges FASTER when a USB cable (with power) is connected to it. Everyone should have things like this! They’re all over the place online!

P.S. The case that I used to fit everything in, is an old Computer Tech toolkit pouch (originally held a bunch of screwdrivers and things). You can use one if you want, or you can put them in an old lunchbox, Tupperware container, a hollowed-out book, folding picture frames (with some modifications), a *small* briefcase …or try putting them on your backpack, or on a hat! Get creative, the main components are the solar panels and the USB adapter.

The new solar system is up and working we now have a 24 volt system in place. And a big thank you to Bill from Bill and Rosa off grid.
