Kind of depends on the house. It probably does take a football field worth of solar panels to power Micheal Moore's McMansion. However, my house was net positive with only 15 panels (260 sqft), at least it was until I started charging a couple EVs. If I wasn't using Trackers, I'd probably need 300-310 sqft of panels to get the same energy. That's less than 1/4 of the south facing side of my house (less than 1/8 total roof area). My house is 100% electric (heating, cooling, cooking, and now transportation) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/index.html INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
