5 watt solar panel
How do I increase the speed of a solar car ?

Mine’s currently moving 7 seconds per 5 metres, and that’s INCREDIBLY slow. I’ve heard of solar cars moving approximately 2 seconds for exactly the same length. Can anyone please tell me how can I increase the speed of my current solar car? I really am no good when it comes to physics or any of these things.

What’s the best type of tyres, to move on a rubber track?

How do I increase the volt of my solar panel, without increasing the watt? Can I put together two solar panels, of 3 volts each and 1 watt, in serial instead of 1 solar panel, 1.5 volt and 1 watt? Which one will move faster?

OK, let me think whether you are out of your mind or not….
5 meters in 2 seconds equals 2.5 meters in one second. One km has 1000 meters, and one hour has 3600 seconds. So you are asking for a speed of 9km/hr, which equals a fast-walking pedestrian. I would say this is achievable.
But what makes “fast” solar cars different is that they do not take the juice for the motor directly from the solar panel, but the solar panel charges a battery (with high Amp/Hrs), and the motor is not a “toy-style” 3 Volt DC motor, but a motor that can produce incredible torque (thanks to the battery bank’s high current it can supply).
Therein lies your problem.
