Sure. If the voltage and current rating of the panel and the motor are compatible, they can be connected directly.
If the panel produces too much voltage and not enough current, an electronic down-converter is needed.
In the opposite case an up-converter does the trick to raise the panel's voltage to what the motor needs.
If the panel does not produce enough power, the electricity can be stored in a battery and used to run the motor for short periods of time or when the sun does not shine. In this case a battery charge controller is needed in addition to the motor controller which powers the motor from the battery.

Batteries and more batteries. Charge the batteries from the solar modules and run the car from the batteries. But still there is the problem of carrying so many large batteries around with you everywhere you go. It would be like driving a forklift because of so many batteries and then an airplane because you would need a lot of room for solar modules to charge all those batteries.
So first thing we need to do is get all the roads built wider so we can put wings on our cars and thicker to handle the weight.
Not a good idea yet. Give it about 10 more years so we can make better solar modules and smaller batteries. Best to go hydrogen and run your car from water.

the output of a solar panel is dc voltage- so you need a DC motor to hook the panel to - there are a couple solar powered cars that either used a battery, which the solar cell charged, or directly from the solar cell (I personally recommend some kind of battery, so clouds won't interrupt the movement of the vehicle...) just make sure the output of the solar panel(s) is matched to the battery, and the motor is capable of good torque at the battery's voltage... polarity is good too...

It is possible, but not a very good idea.
The output of the panel varies too much
over the course of a normal day or with the
passage of clouds.
The motor needs stable input for proper
operation.
