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 ARRAY
 POWER TRACKERS
 ELECTRIC MOTOR
 SPEED CONTROLLER
 CHASSIS
 BATTERY
 WHEEL

6. 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.

7. 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.

8. 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.

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.

14. Mechanism

15. Advantages
Reduced
Polution
Reduced
Energy Cost
Produce less
noise
Unlimited
Source

16. Disadvantages
High initial
Cost
Lesser speed than regular
car
Less efficient in cloudy
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.
