CONTENTS What is Solar Car? History of Solar Car Components of a Solar Car Mechanism Advantages Disadvantages Application Conclusion Reference
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.
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.

Components of a Solar Car
SOLAR ARRAY POWER TRACKERS ELECTRIC MOTOR SPEED CONTROLLER CHASSIS BATTERY WHEEL
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.
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.
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.
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.
Electric MotorAn 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.
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.
Speed ControllerThe 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
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.
Mechanism
AdvantagesReduced Polution
Reduced Energy Cost Produce less
noiseUnlimited Source
Disadvantages High initial Cost
Lesser speed than regular car
Less efficient in cloudy weather
Limited to Solar regions only
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.
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
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.
