Answer
The project you are considering is nearly impossible if you try to do it from scratch.
It you buy a kit, you have a chance.
Go read up on the dedicated helicopter forums:

How do I win a solar car race?

awesomenes

I need to know what is the best set up and vwhat techniqiues I should use,man. Come on I realy ned dis.
I need to know how to win a race with a mini solar car.I know that you have to make it light but I need other info.

Answer
If you are talking about a small size (as in toy car sized) solar car, then skip the batteries if you will be racing in an area that has full sun exposure. Use the the most efficient light weight solar cell available, and use a high efficiency motor (the type used in mini RC helicopters). If you need to use a battery, use the type that is used in cell phones and mini sized RC vehicles.... lithium polymer batteries (aka lipo batteries). They require special care, so be careful with them to avoid a fire, and read about them before you buy them.
