As components become more efficient you will be able reduce the amount of energy wasted as heat.
Solar will never be able to power a RC racing rehicle (high speed, fast acceleration) nor a full speed car.
They could be used to suplement them though.
I was toying around a few years ago at taking two rc bodies (would have used my T4 for it) and putting a layer of solar cells between them. It would not create enough electricity to run the vehicle, but if you started with a fresh battery the solar cells would increase your runtime. The problem (with it being done inexpensively by an amature (non Elec Eng) would be that if you stop the car, but leave it in the sun you might overcharge the batteries.
In terms of power creation, with present technology I would not expect you could fit more then ~500ma (or less) at 7.2 volts. How much current draw does a stock (brushless) motor draw?
