    Solar Panel Roof

    Hello, a newbe here,

    How come that nobody is using built-in solar panels in the car roof? They could feed the a/c and also charge the batteries. Would be nice to be able to have the a/c running while you are shopping in the summer, plus it would increase fuel economy if the a/c was disconnected from the motor.

    The amount of surface area on the roof of a car isn't very big. If you aren't careful, the drag caused by adding cells could waste more energy than the cells produce.
    A good smooth design, however, could be used at least to drive a fan to circulate air through the vehicle. I doubt that there's enough energy generated to actually run the airconditioner and it certainly won't get you very far by charging the batteries. I've seen estimates of maybe 1 mile per day in the middle of the summer. Kind of like the Mars Rovers that have maxed at about 1 km in a day. The Rovers, however, have very expensive, multi-junction cells.
    If you really want a solar powered car, wait until plug-in hybrids or pure EV's are available and put solar cells on the roof of your house to charge them.

    Like he said above, it would be a good option for circulating air through the cabin to hopefully keep the temperature down. It could also trickle-charge the battery. Every little bit can help.

    Theres a new type of solar

    Theres a new type of solar panel...which is a more efficient energy collector...i think its called sliver panel...or somthing...plus.its transparent...and it can be applyed as paint....because the cells are so tiny...can be applyed as clear coat for the car...lol...i think green colour is gonna help more energy collected..i think.

    I belive this is one way to extend range and milage on the battery system along with using the Euro spec full electric swith and some other computer tricks on the market. solar is untaped for this use.

    I dont belive drag would be an Issue, just add a small wicker bill along the top of the windshild to direct air over the roof panel.

    The newly redesigned Toyota

    The newly redesigned Toyota Prius comes standard with solar cells on the moonroof which power ventilation and air conditioning.

    we are just ramping up a solar roof in series production for a hybrid sports car, check out our home page! In average, the OEM expects that you can drive approx. 200 miles per year from the power supplied by the solar roof! Not too bad ...

    That's what gets me about

    That's what gets me about the green movement. It sounds great until you try to do something, and then out rolls the caveats. I tried putting solar panels on my roof and the company selling the solar panels told me to "wait a year, and maybe they will be more efficient". I mean come on. We don't give a damn about pushing air through the car cabin. WE WANT TO TURN THE WEELS TO MAKE THE CAR MOVE! Don't over-sell this stuff until you can back up the words. The world awaits anxiously, me included.

    Really not huge fan of these panels.. They are very expensive with little efficiency.. Really hope these panels will become more effective in future..
