ABSTRACTSTo design a car with high efficiency by using alternative energy sources to achieve optimum performance.

OBJECTIVES

☺Reduce ,Reuse, and Recyclesolar energy is a renewable energy no pollutionenvironment friendly

☺Malaysia has abundant of sunlight throughout the year, car travel on land easy to get sunlight.

☺To spawn an alternative energy source to countries.

SCIENTIFIC THEORY

Sunlight energy

Electrical energy

Kinetic energy

INNOVATIONSCHOICE OF GEAR

Ratio of gear1:3

CHOICE OF BUILDING MATERIALS

CHOICE OF TYRESBig-if the perimeter of the tyres increases, the tyres travel more longer for one cycle.Light-reduce the total mass of the car,so the car can move faster.Thin-reduce the friction between the tyres and the surface.

CONSTRUCTION OF DESIGN

PROCEDURE1) Make car’s chassis.2) Solder solar panel.3) Connect solar panel to

motor.4) Combine the chassis, motor

and solar panel.5) Testing.

DISCUSSION1. Built of solar car: we managed to

built the solar car in firm structure .

2. Solar circuit - using series electric circuit and function well

- current : 0.5A - voltage : 1.0V - power : 0.5W3. Performance: the car moves

smoothly with good speed.4. Reduction of air resistance : The

friction is decreasing due to the aerodynamic design .

CONCLUSION

Solar energy can be used to move a car. Hence it can be used as an alternative energy
