SOLAR POWERED VEHICLES Morgan Stelli
HOW THEY WORK
Solar cars harness energy from the sun, converting it into electricity
That electricity then fuels the battery that runs the car's motor
Instead of using a battery, some solar cars direct the power straight to an electric motor.
SCIENCE OF SOLAR PANELS
Solar panels work because of photovoltaic cells (PVC) PVCs convert the sun's energy to electricity Made up of semiconductors, usually silicon, that absorb light Sunlight's energy frees electrons in the semiconductors,
creating a flow of electrons That flow generates the electricity that powers the battery or
motor
Tokai ChallengerThe 2009 winner of the World Solar Challenge, held on a 1,864-mile course in the Australian desert outback.
It had an average speed of 63 mph

University of Michigan Infinium
Built for speed and setting records, not passengers
Finished first in 2010 American Solar Challenge
PRACTICAL USEShttp://www.youtube.com/watch?v=9Jsqf5CEUI0
ADVANTAGES
Non-polluting Renewable energy Other than installing and repairing solar panels, no cost
DISADVANTAGES
Cannot power large vehicles Cannot typically reach highway speeds A lot of panels necessary to power small car Expensive to fix if broken Expensive to install
