Let's discuss the solar panel/roof issues that were brought up in http://www.mynissanleaf.com/viewtopic.php?p=142154#p142154" onclick="window.open(this.href);return false; (Nissan LEAF Engineering Team Visit December 3rd) so that we can keep the other topic on track.
I wanted to bring up a few points. AFAIK, the solar roof panel on available on the 3rd gen Prius only can deliver about 60 watts max. See http://priuschat.com/forums/gen-iii-2010-prius-accessories-modifications/57681-hacking-solar-9.html#post917560" onclick="window.open(this.href);return false; and a few posts further down. You can probably find more posts by Googling for siteriuschat.com solar roof watts. It only runs the ventilation fan when the car is parked. 5 kw seems completely impossible. I don't know state of the art in solar, but even 1 kw sounds way off.
I hope people realize that 1 hp = ~746 watts.
Some people pointed out 200+ watts for minimal AC. 200 watts is REALLY minimal and doubt it'd do any good. I can tell you that when looking at Scangauge on my 2nd gen Prius that when idling, my car draws ~1.2 - 2 amps (@~220 volts). If I I turn on my (electrically driven) AC, the draw becomes 4.x to 9.x amps, sometimes even 10 amps (I've posted the numbers at http://priuschat.com/forums/gen-iii-2010-prius-fuel-economy/68603-same-prius-not-same-mpg-11.html#post1146128" onclick="window.open(this.href);return false; before).
On Priuschat, we were disappointed to learn that the solar roof couldn't charge the HV battery. Some explanations were given at http://priuschat.com/forums/gen-iii-2010-prius-main-forum/60635-scientific-american-article-2010-prius.html" onclick="window.open(this.href);return false; and http://priuschat.com/forums/gen-iii-2010-prius-main-forum/60635-scientific-american-article-2010-prius.html#post831221" onclick="window.open(this.href);return false;. I'm no EE so I can't comment on the accuracy of that. Others can chime in on that.
