Prius to Get Solar Panels?

Toyota will reportedly introduce a Prius equipped with solar panels next year. Just don't count on the sun to drive the car.

Toyota plans to roll out a Prius model equipped with solar panels on the car’s roof next year, according to Nikkei.

The Japanese business daily reported Sunday that electricity from the panels would make up a portion of the 2 to 5 kilowatts needed to run parts such as air conditioning.

Whether a solar-panel equipped Prius would have popular appeal remains to be seen, given that the car maker has offered no details, such as pricing and availability. Solar panels also add weight to the car, reducing fuel efficiency. Toyota is supposed to be working on making Prius lighter to achieve the opposite, according to Nikkei.

Toyota is not the first company to consider the concept of putting solar on a car. Fisker Automotive last year unveiled the Karma, a plug-in hybrid with a solar panel on the roof, which it plans to produce for a price tag starting at $80,000 in the fourth quarter.

But today’s solar-power technology is far from good enough to actually propel these cars down the highway.

The Prius, a gasoline-electric hybrid, relies on electricity generated by the engine that is stored in a battery.

Toyota, along with its competitors, understands that the future of fuel-efficient cars lies in advanced batteries. That is why it has invested heavily on improving lithium-ion batteries that can store far more energy than the current nickel-metal hydride version (See Toyota Drives Towards Greener Fleet).

Toyota made the right bet more than a decade ago by launching the Prius in its home market in 1997 and in the U.S. in 2000. The No. 1 hybrid company has enjoyed brisk sales of the Prius, along with waiting lists in some places, and it has been growing production to meet consumer demand. The company expects to produce 450,000 Prius cars in Japan in 2009, up 60 percent from last year. The numbers for 2008 are not yet available.

But Toyota will face a growing competition as others, such as General Motors and Honda, which was first to the hybrid market, release more hybrid model vehicles.

GM plans to launch a Chevy Volt that will include a new plug-in hybrid technology (see Chevy Volt Clears for 2010 Production). And Tesla Motors, a startup carmaker in San Carlos, Calif., last week said it would begin making all-electric Model S, a four-door sedan, in 2010 (see Tesla: We’ll Build Electric Sedans in California).

    Total marketing crap… solar has no place in the transportation market

    Take a look at http://www.Aptera.com.

    The Aptera has a solar panel integrated into the roof to run a heat pump instead of a typical air conditioner.

    Aptera has said it will begin production in October from a factory in Carlsbad, CA. Very cool and zippy looking to boot.

    Nothing like a gimmick, I suppose, to make the gullible public
    think something significant is here. Appaently they need something to keep the natives from getting restless while they spend the next 4 years figuring out how to use those li ion batteries they so compleyely rejected just 3 months ago, but are now going into their plug-in hybrid.  Toyota sucks.

    Thanks for pointing out Aptera. I like its futuristic design. We also have written about LA-based Venture Vehicles, which is developing a plug-in hybrid and an all-electric two-seaters.

    Why not use the solar panels to charge the batteries while the car is parked outside during the day?  Your commute home from work could be free (on sunny days, at least).

    It’s clear that you won’t get much extra mileage from the solar panel.
    Instead, it could and should run the air conditioning system,
    also when the car is parked in the sun, and nobody’s there.
    Makes sense also with all the ordinary ICE-cars, maybe even more.


    This is not a new idea, see e.g.

    The idea of using solar energy to power the air conditioning sounds great. The issue is price, isn’t it? Audi A8 is not affordable to the masses. So car makers aren’t going to make much money from offering that option, and solar cell makers aren’t going to make much money from selling to car makers—at least not now.

    TOKYO (AP) - Toyota’s ecological Prius gas-electric hybrid will become even greener next year with solar-powered air conditioning on some high-end models, The Nikkei reported Monday.
    The solar panels on the roof of the new Prius model will provide 2 to 5 kilowatts of electricity, the major Japanese business daily said in a report without
    citing sources.

    ...
    Adding solar panels to a mass-produced vehicle would mark a first for a major automaker, The Nikkei said.

    I’m sorry, we seem to be quoting from the same source…
