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.

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 Cells.

How it work?

Components

Solar Array Power Trackers Batteries Motor Controller What Will Happen if There is No Sunlight

Solar Array

Collect the energy from the sun and converts it into usable electrical energy.

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.

Power Trackers

Power trackers convert the solar array voltage to the system voltage.

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.

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.

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

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.

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.

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.

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.
