4. Introduction
• The design of a solar vehicle is severely limited
by the amount of energy input into the car.
Most solar cars have been built for the
purpose of solar car race.
• Exceptions include solar-powered cars and
utility vehicles.
• Solar cars depend on PV cell to convert
sunlight into electricity.

5. 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.

6. SOLAR ENERGY SYSTEM

7. 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.
Solar cells are devices which convert solar energy directly into
electricity. The most common solar cells function by the photovoltaic
effect. Photo- means light and -voltaic means electrical current or
electricity.

8. SOLAR ARRAY
The solar array is the vehicle's only source of power
during the cross-country Race. The array is made up
of many (often several hundred) photovoltaic solar
cells.

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. The number of power trackers used in
a solar car varies with each team's design. Power
trackers can be very lightweight and commonly
reach efficiencies above 95%.

11. ELECTRIC MOTOR
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. An electric motor is a device using
electrical energy to produce mechanical
energy, nearly always by the interaction of
magnetic fields and current-carrying
conductors.

13. 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.

14. CHASSIS
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.

15. CHASSIS

16. BATTERY
Battery is the main power supply of a vehicle. A
battery is a device that stores chemical energy and
makes it available in an electrical form.
