I know this is off the original topic and no amount of information will sway your mind Xenophobe but consider this:
From the paper you quoted on PV cost.
For example, the typical annual output of a flat-mounted 1 kW system in San Diego,
California, is about 1,310 kilowatt hours (kWh), while the same system in Seattle,
Washington, would produce about 850 kWh.1 As a result, the LCOE of the Seattle system is about 1.5 times greater than the San Diego System, ignoring any differences in
financing and incentives.
Lets take a round figure average from that quote and say that the average US location could yield 1000 kwh/ year from a 1000 watt roof top system. Now how big would your system have to be to charge your Volt and how much would it cost?
As we have figured out above to run a Volt 15,000 miles at 12.9 kwh/charge takes 6450kwh per year. It happens I have a catalog here that has solar panels in it on sale. Each 5.2X 2.7 foot panel is rated at 180 watts and is on sale for $700. 6450/180=35.8 so
36*700=$25,200 We will skip the shipping and installation costs and assume you have 500 square feet of south facing roof. There is of course a tax credit available and I'm sure you will want to claim the 30% credit which will drop your cost to $17,640. We will also assume that you can use smart grid technology to pump power into and back out of the grid at will without any losses or cost. This saves you the cost of another battery as big and expensive as the one in the Volt ( $8000)to store sunshine that falls on your roof while you and your car are at work. Now lets assume that the car and the panels both last ten years but have zero salvage value. You will argue that of course but lets assume it balances the shipping,and installation cost, increased insurance costs etc. we have ignored.
So in ten years the panels will produce 64,500kwh of electricity at a cost of 27 cents per kwh and your car will have a (Fuel/electricity) cost for 150000 miles of 11.78 cents per mile. And with an initial cost after tax credits of $32,500 You start with a base of over 33 cents per mile before you add in registrations, state taxes ,insurance, maintenance and repairs which might be considerable if you have to change out a battery.
Now compare to a $17,000 Toyota Corolla getting 34 mpg hwy. 30 combined. Gas would have to be over $6.62 a gallon average over the life of the car before the Volt has a chance to break even with it.
If you want to get started on your PV panel installation I,ll give you the Email address where you can order those 180 watt panels.
