That is a very good point, Bill, if we look at the economics of a PV array as replacing transportation fuel instead of kilowatt hours, then the economics are much better.
I'm not sure the accountants will agree, but I like your approach, and if it's your array, you can look at it any way you want.
It's one of the very few ways pv can displace transportation fuels.

Comments from an EV'er.
I applaud Reliant's commitment to the long term electrification of the transportation sector. See <http://electrificat ioncoalition. org/>
The power for an EV can come from any of a number of sources. I have done the math for home installations of photovoltaic arrays. The financial analysis entails an investment for say 1.6 kWatt of panels. That will make power for a 30 mile
daily commute. The cash flow for the life of the panels is as follows: Don't pay for gasoline. Don't pay for gasoline engine related expenses. Pay for battery replacement. Don't pay for PV power generated. Look at the rate of return for this investment, and the rate of return is good! Today!
Sure, driving an EV is a lifestyle change.
For 25 years, you want to take bets on the price of gasoline or the price of traditionally generated electrical power (coal, nuclear or natural gas...) Want to take bets on the cost of PV generated power. I suspect that all costs in this area will be coming down.

Subject: [hreg] Electric cars produce twice as much CO2 as gasoline powered vehicles?
A letter to the editor in today's Chronicle quotes "a recent article in National Geographic that with a coal-fired energy source, a zero emissions electric vehicle actually is
responsible for more than twice the amount of carbon dioxide as produced by a conventionally powered gasoline vehicle."
If this is so, do we still want to drive these "clean" vehicles? Here is a link to the article (scroll down to the 5th letter "A Fly in the Ointment")
