3. INTRODUCTION
»Solar car is a solar vehicle used for land
transport.
»Solar is combined technology typically used in
the aerospace, bicycle, alternative energy and
automobile industries.
»Design of a solar vehicle is severely limited by
the amount of energy input into the car.
»It is made up by Photovoltaic cells which
provides power to run the vehicle.

4. HISTORY
 In 1829 ALEXANDRE EDMOND BECQUEREL
discovered that certain materials produced
electric current when exposed to light.
 First solar car invented was a tiny 15-inch
vehicle called SUNMOBILE by WILLIUM G.
COBB of General motors corporations.
 COBB showcased this car at Chicago Powerama
Convention on 31 August, 1995.
 It was made up by 12 Selenium Photovoltaic

5. How it work?

6. Components
 Solar Array
 Power Trackers
 Batteries
 Motor Controller
 What Will Happen if There is No Sunlight

7. Solar Array
 Collect the energy from
the sun and converts it
into usable electrical
energy.

8. How solar array change sunlight to usable
energy?
 First thing the solar
array collect sunlight
together.
 When sunlight is
collected together. It
immediately change the
sunlight to electricity.
 Next step is to the power
tracker.

9. Power Trackers
 Power trackers convert
the solar array voltage
to the system voltage.

10. Power tracker role
 In this step the power
tracker in the car
receive the energy from
the solar array, and
change the energy that it
receive to energy that
the car can be use
 After it convert energy,
it send the energy to the
battery.

11. Batteries
 The batteries(eg. NiMH,
NiCd, Lithium ion &
Lithium polymer) store
energy from the power
tracker and makes them
available for the motor's
use.
 They operates in a range
of 80 to 170 volts.

12. Motor Controller
 The motor controller
adjusts the amount of
energy that flows to the
motor to correspond to
the throttle.
 The motor uses that
energy to drive the
wheels

13. How Solar-Power Car runs?
 When the energy is send
from the battery to the
motor, the motor adjust
the amount of energy
that flows to the throttle.
The motors use the
energy that receive to
run the wheel.
 This is the process how
solar car runs.

14. Solar Car brake
 Kinds of breaks:
 Friction brake is a type of automotive that
restore heat in the rotating part (drum brake or
disc brake) brake during the application and then
release it in the air.
 Drum brake if you press with your leg the brake
is connected to the wheel that is spinning.
 Disc brake this one brake all the wheels together
and make the car slow down or stop at that
moment.
 Hand brake is emergency brake e-brake, slide
stick, or parking brake.

15. 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 batterie will
be used.

16. ADVANTAGES & DISADVANTAGES
ADVANTAGES
 No noise pollution.
 No green house gases
produced.
 Solar energy is free widely
available.
DISADVANTAGES
 SAFETY ISSUE-Cars should
be sturdy & able to hold up
safely in case of an
accident and lightweight
solar cars are not quite
there yet.
 The cost is not just viable
due to use of no. of panels
required for power.
 Average family would not
be able to afford.
