SOLAR ARRAY The solar array consists of hundreds of

photovoltaic solar cells converting sunlight into electricity. In order to construct an array, PV cells are placed together to form modules which are placed together to form an array. The larger arrays in use can produce over 2 kilowatts (2.6 hp).

WORKING OF A SOLAR ARRAY

POWER TRACKERS Power trackers convert the solar array voltage to the system

voltage. 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, they help to protect the batteries from being damaged by overcharging.

BATTERIES The batteries store energy from the power

tracker and makes them available for the motor's use.

Batteries that are commonly used in solar cars are:

• Lead-acid • Li-ion• Ni-MH • Ni-Cd• Flooded-cell• Gel-cel

MOTOR CONTROLLER The motor Controller is an electronic device that

controls the amount of power delivered to electric motor according to the signal from the potentiometer connected to the throttle pedal.

The motor controller adjusts the amount of energy that flows to the motor to correspond to the throttle.

MOTOR An electric motor is the basic and important part

of the solar car. It is a device which uses the electrical energy to produce mechanical energy.

The motor uses that energy to drive the wheels of a solar car.

HOW DOES IT WORK..??

IF THERE IS NO SUNLIGHT..?? If there is no sunlight like in the nights and

on a cloudy day, the emergency batteries will be used to run a solar car.

Another way for getting the battery recharged so as to run a solar car when there is no sunlight is by recharging the batteries from the sun stations where the energy from the sun is stored for future use.

DESIGN OF A SOLAR CAR The shape of the solar car should be

designed in such a way that the air around the car flows smoothly by causing less drag.

According to the Bernoulli’s principle, the pressure of air decreases as its velocity increases. By creating enough lift the car becomes lighter as it moves, hence producing better speeds.

TILTING PANEL The suns rays may not fall on the solar

panels directly, as the sun moves from east to west according to the time. Hence tilting panels are used so that by tilting the solar panels, we can allow the suns rays to fall directly on the panels.

ADVANTAGES OF A SOLAR CAR A solar car has zero harmful emissions hence

it is eco-friendly. It uses renewable source of energy which can

never be exhausted. They work silently hence no noise pollution. As the life span of solar modules is more than

30 years the life span of a solar car is also more when compared to a regular car.

The fuel used is sunlight which is unlimited and free of cost.

DIS-ADVANTAGES OF A SOLAR CAR A solar car provides less speed. It is expensive. Maintainance cost of a solar car is high. Due to their light weight body and small size

they are considered to be dangerous in case an accident happens.

Performance of a solar car will be affected in unfriendly weather conditions, like on a cloudy day or when night falls.

APPLICATIONS OF A SOLAR CAR Solar cars are used in industries where small

vehicles are used to perform light weight conveys work from one place to another.

These vehicles are primarily manufactured for racing competitions and engineering exercises.

It is used as day to day transportation device. They are used in places where, fuel based

vehicles are banned due to production of pollution and noise.

They are often used and sponsored by government agencies.
