3. What is a Solar Car?
▶ A solar vehicle is an electric vehicle powered by a type of renewable
energy, by solar energy obtained from solar panels on the surface of
the vehicle.
4. History of Solar Car
▶ First Solar Car was invented in 1955 by Willam G. Cobb.
▶ That was called “SUN MOBILE”.
▶ It had 12 PV cells and the size was about 12 inch.

5. Components of a Solar Car
▶ SOLAR ARRA
Y
▶ POWER TRACKERS
▶ ELECTRIC MOTOR
▶ SPEED CONTROLLER
▶ CHASSIS
▶ BATTERY
▶ WHEEL
6. Solar Cell
▶ A solar cell converts solar energy to electrical energy.
▶ Photons in sunlight provide the energy that moves electrons from one layer
of a semi-conducting metallic wafer to another.
▶ The movement of the electrons creates a current.
▶ The most common solar cells function by the photovoltaic effect.
▶ “Photo” means light and “Voltaic” means electrical current or electricity.
7. Working Principle of Solar Cell
▶ When sunlight falls on the PV Cell, it absorbs the energy from photons
and free the electrons from the Semi-conductor.
▶ A flow of electrons takes place which produces an electricity.
8. Solar Array
▶ The array is made up of many (often several hundred) photovoltaic
solar cells.
▶ It collects the direct sun radiation and converts to electricity.It is
the main source of power to the Solar Car.
▶ The power produced by the solar array varies depending on the
weather, the sun's position in the sky, and the solar array itself.
9. Power Trackers
▶ Power trackers condition the electricity coming from the solar array to
maximize the power and deliver it either to the batteries for storage or
to the
motor controller for propulsion.
▶ When the solar array is charging the batteries, the power trackers help to
protect the batteries from being damaged by overcharging.
10. Electric Motor
▶ An electric motor is a device using electrical energy to produce mechanical
energy.
▶ An electric motor is the basic and the most important part of a solar car.
▶ It should work with optimal power and the efficiency should be high.
▶ It is used to drives the wheels.
11. Battery
▶ After the power tracker convert the energy to the energy that is
usable for the car, it send to the battery then the battery store the
energy.
▶ This energy is send to the motor and controller to make the car run.
12. Speed Controller
▶ The purpose of a motor speed controller is to take a signal representing
the demanded speed, and to drive a motor at that speed.
▶ The controller may or may not actually measure the speed of the motor.

13. Chassis and Wheels
▶ The primary challenge in developing an effective solar car chassis is to
maximize the strength and safety, but minimize the weight.
▶ However, safety is a primary concern and the chassis must meet stringent
strength and safety requirements.
▶ The wheel should be Light weight and should posses good road grip.
16. Disadvantages
• High initial Cost.
• Lesser speed than regular car.
• Less efficient incloudy weather.
• Limited to Solar regions only.
17. What Will Happen if There is No
Sunlight?
▶ If there is no sunlight, the
emergency batteries will
be used. Example in the
situation that there was a
large cloud cover the sky,
this emergency batteries
will be used.
18. Applications
▶ This concept can be utilized to build a single sitter four wheel vehicles in
practice.
▶ It can be extended to more commercial form of four wheeler vehicle.
▶ In industry where small vehicles are used to perform light weight conveys
work from one place to other place.
▶ It can be used places where, fuel based vehicles are banned due to
production of pollution and noise
19. Conclusion
▶ Solar Car would be an amazing advancement in future car technology.
▶ They would allow free and pollution less travel with unlimited accessibility.
▶ If some minor drawbacks associated with Solar Car can be rectified, then for
sure Solar Car will play a vital role in future transportation.
