If we could quantify that the juice required to run the car normally with accessories off was low enough...
1 Watt DLRs for $10(US): Product Listing - CAR

Come to think of it, it would be easy to measure:
Start the engine, disconnect battery positive and put an ampmeter inline between the battery post and the cable, then disconnect the alternator, and read the meter.
It should tell you exactly how much power is being drawn.
Check it at idle and at highway speed RPMs, with what ever acc. you commonly use on. Use whichever reading is the highest, multiply by number of hours you drive a day and you know the size in amp/hours of the battery you would need. (or multiply again by 12volts to get watt-hours for solar recharge need)

So the other day we both returned home at the same time again, only now the weather is warm, sunny, with no wind. And I yell to him: You took the car? In this weather?!?
