Very cool projects. I don't understand all of it, but producing your own electricity is very cool. Ever since I saw a show called "canada's worse handyman" I realize solar/wind is more mature technology than I previously assumed.

What sort of knowledge do you need for these projects? I can solder, and understand the basics of electricity but thats it. I'm checking out the builditsolar, and the "Getting Started" hopefully that'll fill in some gaps.
