Solar panels in gasoline car

pmfman

We all know that an alternator in a car uses a significant portion of a car's HP, thus lots of its fuel efficiency. Thus in theory, if a large enough solar panel (lets say 150 watts) wouldn't this decrease the load on the alternator this increasing HP/fuel efficiency?

 

This is more or less to satisfy curiosity, I don't intend to try it.

  • Interesting idea, but.

    One things is produce additional electricity with solar panels, whatever during drive or during car waiting somewhere. But for reducing looses on alternator, you would need think of disconnecting alternator. And disconnecting of it for maximum saving need to be done on mechanical level. Then you are introducing whole new bunch of problems, and probably will not work efficiently. Of course, you could only disconnect load from alternator, but you still need have any way of connect alternator in days or hours, where would not be enough of Sun.

     

    I just bought 150 Wp flexible PV panel, which I am to plan to mount on my ICE car. And add some extra battery and a lot of other electronics to measure of efficiency of charging via Sun on car.

    In standard life car is not usually parked on the most sunny places, which would be very welcome with PV system on car roof. When I will be ready to show more results, I will post there too.
