FOREWORD

     All of the man made machines require some or the external source to start with. More and more use of computers has caused dramatic increase in energy consumption and more electricity is needed as computers run mainly on them and ultimately the energy is increasing. Therefore using renewable resources like solar energy, and LED’s instead of electricity and LCD, can be substituted and can be used efficiently and ultimately saving electricity.


SCOPE
     The source of power to the computer is electricity, therefore substituting the source of power by solar energy using solar cells and LCD’s can be substituted by LED’s.

INTRODUCTION

     The objectives are

 To design a alternative source of energy for computers.

 To design that source of energy in such a way that it should be eco-friendly.

 To design a alternative display system for the computer monitors.


DEFINITIONS

1. PERFORMANCE REQUIREMENTS

 The solar cells must be eco-friendly.

 It must be clean, non-polluting energy.

 They must be silent in operation.

 They must be self-sufficient, must not require refueling.

 They must be at least a warranty of ten years.

 The efficiency should be better than that of electricity.

 The display manner should be clear and perfect and should not cause any strain to eyes.

2. MANUFACTURING REQUIREMENTS

 The computing systems will be set up with solar panels or plates which consists of solar cells.

 They are made up of mono crystalline silicon wafers.

 All the settings should be very accurate and must take less than twenty minutes.

 The mechanism and the complete product must be manufactured and finished using the limited raw materials.

3. ACCEPTANCE STANDARDS

     According to the (ROHS) restriction of hazardous, waste and electrical and electronic equipment (WEE) that ensures the smooth transmission and development of the product.

 The solar computing instruments should be free provided with non explodable cells.

 The cost of the cells should not be more than 300 - 400 (rupees) only.

 The voltage produced by these cells should not be more than 4V.

 The output of these solar cells are separately achieved by connected wires through the other end of the cells and care is taken not to mix wires.

 Inspection is done before the assembly is done.

 The LED’s should be assembled exactly to their X, Y axis.

4. DISPOSAL
     The solar cells and the LED’s should not be disposed off in the open environment rather they should be recycled and can be used efficiently.

5. OPERATIONAL REQUIREMENTS

 Placing the solar cells must be done according to the direction of sun.

 The wires of all the solar cells should be connected to an external circuit which neutralizes and also prevents short circuiting.

 There should not be any internal shocks.

 The dimensions of the LED’s should be exactly known.
