Wait, really?!? I’m completely new to the area of home backup, but this announcement is in-line with the time that I’m researching solar for our home (on-grid). It doesn’t make sense given our 1-2day/year electricity outages to backup. Even with that though, how is $5k possible? http://www.wholesalesolar.com/back-up-power Their 9.6kWh system is $6.79k - am I completely misunderstanding something? thanks, -lev _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
