"For storage a $65 lead acid automobile battery does the trick. It’s 12V so can be charged directly from the solar panel, and holds 420Wh, way more than I use in a day. That’s $0.15 / Wh so I don’t see why everyone is so excited about Tesla charging $0.43 / Wh for the Powerwall, sans inverter and installation." I would like to refer you to this wonderful article. http://www.thebestpageintheuniverse.net/c.cgi?u=iphone http://www.thebestpageintheuniverse.net/c.cgi?u=iphone
