The Sun !
Sunlight + solar panel = free energy.
No because they are powered by solar energy! Hence the name 'Solar Car'
When a solar-powered car is moving, the energy conversion involved is solar energy being converted into electrical energy by solar panels, which is then stored in a battery. The electrical energy stored in the battery is then converted into mechanical energy by the motor to propel the car forward.
How does a solar powered car stop
It either has solar energy stored in a battery or it doesn't move.
Solar powered cars are battery powered cars. The solar array is charging the batteries. So there is no real difference.
Solar powered car's solar panels and windmills relate because they both use renewable energy resources, the sun and wind respectively.
The cheapest solar powered car is $5,560 (this car is Chinese). The most expensive solar powered car is between $284,000 (Australian) and $1.5 million dollars (possibly American or European)!!
the solar powered car was invented by Alfred Pandori 1985
the first solar powered car , also known as the "sunmobile"
