Unfortunately it doesn't scale like that. Maybe disabling the alternator on a super efficient car like the Honda Insight could improve fuel economy by 10%, but electrical loads represent a smaller portion of total energy use in larger vehicles.

Kinda like how I could tell when my AC kicked on in my old and weak Subaru. AC represented a larger load on that vehicle than, say, my 7,000 lb Dodge Ram 2500 diesel.

That said, seems a worthwhile project since the solar is already installed and available to be utilized.
