Part of the 7.2 kW system in Bayview, WI USA (South of Milwaukee, WI). This is very likely the largest residential solar installation in Wisconsin. This home also has a detached garage, and the south facing roof of the garage is totally covered with PV panels as well.
This photo was taken during the fall of 2007 when I was on a tour of residential solar power installations in the Milwaukee area. It was so inspiring to see all of the small scale renewable projects that individuals are doing. It is my hope that the US government begins supporting these grass roots efforts on a much more meaningful scale in the very near future.
It is "Time for Change." It is time for renewable energy to be taken seriously by government leaders in the US.

24 is better but 12 is cheaper.

it all depends, since you’re going to be spending top dollar for the panels anyways you should just go with the best. 24v would essentially be better in the long run because it can carry a heavier load, but if you’re trying to save a few bucks get the 12v which isn’t bad, but expect more limitations.
