Smitty, Since you mentioned Sean's bus I thought you would be interested in more info from a solar thread I had posted a while back- (sure you read this but thought since you asked it just gives one persons usage & equipment requirement info & it looks like quite a system... thread: viewtopic.php?f=11&t=4516&p=38725#p38725
This is SeanF's usage on his bus:
Sean, What wattage panels are you using? Actually if you don't mind what is your system comprised of - panels, batteries, inverter etc? I am curious as to the approx useage (wh) you are using daily & the sytem you have set up... Thanks!
4 x KC120 panels (120 watts each, tilted to 50 degrees in winter months)
400 watt wind turbine (not currently set up)

MorningStar Tri-Star TS-45 solar charge controller

I use about 80-100 amp-hours per day (960-1200 watt-hours).
Desktop PC/flatscreen monitor 9 hrs/day x 5 days/week
Laptop computer about 60 hours per week
Satellite internet modem, router, 60 hours/week

That's about it.
