A solar car is an electric vehicle powered by solar energy collected from solar panels on its surface. It consists of solar arrays to collect energy, power trackers to maximize power delivery, an electric motor for propulsion, a speed controller, a lightweight chassis, batteries for energy storage, and wheels. Solar cells in the arrays convert sunlight to electricity, which is either used to directly power the motor or stored in batteries. Power trackers condition and maximize the solar energy delivery. The motor provides mechanical power from the solar-generated electricity to drive the vehicle.

2. WHAT IS 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. SOLAR CAR CONSISTS OF:
SOLAR ARRAY
 POWER TRACKERS
ELECTRIC MOTOR
SPEED CONTROLLER
CHASSIS
BATTERY
WHEELS

5. 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 semiconducting 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

6. 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.

7. The power produced by the solar array varies depending on the
weather, the sun's position in the sky, and the solar array itself.
On a bright, sunny day at noon, a good solar car solar array will
produce well over 1000 watts (1.3 hp) of power. The power from
the array is used either to power the electric motor or stored in
the battery pack for later use

8. 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%.

10. 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.

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
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.

14. 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.

15. Application of solar car:
• 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
