The document discusses the components and working of a solar vehicle. It describes that a solar vehicle is powered by solar energy collected from solar panels on its surface. It then explains the key components of a solar car including the solar array, power trackers, electric motor, speed controller, chassis, and battery. The document outlines how solar cells convert sunlight into electrical energy that is either stored in batteries or used to power the motor. It also discusses the advantages of solar cars in reducing pollution and energy costs, as well as some disadvantages like high initial costs and lesser speeds than gasoline cars.

3. What is aSolar 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.
▶ Aflow 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.
ELECTRIC MOTOR

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.
REMOVEABLE BATTERY

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.
Speed Controller

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 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.
