I think you can get 15W/sqft and my Volt is not very efficient I often
need 16KW if I take it easy but even at 8kw you would need 533sq feet
of solar panels 23ft by 23ft. So... not a great deal but with a 32KWh
battery pack you could charge it with a 23x23 panel on your roof in 4
hours. That sounds like a better deal and very manageable.
