An AP report is generating headlines around the world:
Toyota Motor Corp. is secretly developing a vehicle that will be powered solely by solar energy ...
According to The Nikkei, Toyota is working on an electric vehicle that will get some of its power from solar cells equipped on the vehicle, and that can be recharged with electricity generated from solar panels on the roofs of homes. The automaker later hopes to develop a model totally powered by solar cells on the vehicle, the newspaper said without citing sources.
Getting some electricity from rooftop PV panels isn’t news, though it is a good idea, if only a “symbolic gesture” until panel costs drop sharply. (See also Treehugger’s “Solar-Powered Toyota Prius Project.”)
But there isn’t enough rooftop area to run a car solely on rooftop solar cells. I don’t see how it would work even for an ultra-lightweight short-range city car with a really big roof area—an ungainly, unaerodynamic design. And don’t forget, cars are often parked inside.
Toyota Motor Corp. is secretly developing a vehicle that will be powered solely by solar energy in an effort to turn around its struggling business with a futuristic ecological car, a top business daily reported Thursday.
Toyota struggling? It had a loss this year, true—the “first since the Japanese automaker began reporting results in 1941”! Meanwhile, its biggest competitor is on the verge of bankruptcy.
Yeah, I’d like to struggle that much. In any case, long before any solar car could be ready to market, Toyota will be the biggest and most profitable car company in the world.
The Truth About Cars says there is no truth to this story, that it was just lost in translation—see Toyota Allegedly Developing Solar Car: A Case Of Too Much Sake.
Still, I ran Chrysler to electrify entire product line, which some commenters thought should have been filed under humor. Let’s file this under Don’t hold your breath ‘media’—since they probably got the story wrong.

Hmmm...
How about this Joe? Solar mirrors along the highway that track the car's roofs and put about 30 suns on them? Hehey.
And solar carports that concentrate 30 suns on the roof for stationary battery charging.
You would need the battery storage for clouds and night travel though. Or an induction strip under the highway, or a backup solid oxide multi-fuel cell/turbine backup generator. Or all of them together, on a Hypercar.
And a solar PV array that could handle 30 suns, with maybe 50% efficiency? And some of that miracle silicon airgel insulation to protect the car from the heat. And liquid cooling for the PV array, that generates extra power.
And Toyota can't seem to make a plain old mass produced plugin hybrid Hypercar yet? Well I guess they do have a prototype anyway.

I just wish AP would proofread their stories!
I notice so many typos that I thought were being made by my local newspaper. Turns out they were all AP stories. For crying out loud learn English before trying to use it in the newspaper and spell check is there for a reason, USE IT!

Really?
I mean, I'm all in favor of solar power. Ultimately, I think it will be the one to go with. But not for cars. Solar cars are just a joke; a marketing gimmick that will never work. Instead of investing millions in a new solar car, why don't they work on the PV technology itself? ...then license it to others for a nice profit.

Translation Error
Likely a translation error involving the fact that "ALL new Prius's will now have a solar panel"
Catch being it's just a tiny panel, designed to improve the battery life, by topping off the batteries with a trickle charge.
It doesn't actually improve driving range. (Much less drive the whole car entirely)

Toyota sez
Via Autoblog:
However this 962 pound, Prius-like performance, carbon fiber reinfornced plastic vehicle could be powered by solar on the garage, carport, or over a parking lot.

Ahh
That makes more sense.
A solar powered car port.
(Likely net metered, rather than battery storage)

Yep Dave
There should be enough space to power every plugin hybrid for it's electric miles, just with solar insolation hitting suitably exposed parking lots, garages, and car ports.
3 kwhs per day for these ultralights, ought to power the average daily drive. If it could be distributed via smart grid and used to recharge at the appropriate time, parked at home, work, school, or shopping, the whole system would work to store it's own energy.
Maybe even storing a surplus for grid backup.
Sunflower's estimate of 25 kwh per day average from a 4 meter dish would indicate that a garage or carport roof would be more than enough with double the area of the dish, due to the lower efficiency.
Maybe 20% of the parking land use, with roof mounted concentrating solar, could power the plugin power for these type of PHEVs.
