History of solar car• The first solar was invented in 1955 by wiliam g.cobb.• That was called “SUN MOBILE”.• It had 12 PV cells and the size was about 12 inch.

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 (generally, the roof) of the vehicle.

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.

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.

7Solar array

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

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 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.

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.

15

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.

• Solar car reduces pollution,reduces energy cost .• Solar powered cars do not require any expense

for running.• Solar car require very low maintance .• Solar car produces less noise,produces no

harmfull emissions.

Advantages

Disadvantages

• The main disadvantages is that it doesn’t produce enough energy to move or reach high speeds.

• Solar powered cars can operate only for limited distances if there is no sun.

• A good solar powered car is expensive. It will cost $200,000 or more.

• Parts used in solar cars are not produced in large quantity so they are expensive.

• If it is dark out for many days, the car battery will not charge and you this can seem as a problem to many problem. This is the main reason why people don’t rely on solar cars.

What will happen if there is no sunlight?

• If there is no sunlight ,the emergency Batteries will be usedExample in the Situation that there wasa large cloud coversky ,this emergency batteries will be used.

19

Application• 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.

20

Conclusion

• Solar car would be 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 are overcome, it will play a vital role in future transportation.
