India has National Solar Misssion by which they want to have 22 GW of Solar Power by 2022.

Typically a Solar Cell Module is of size 5.5 Sq M    ( Approx 2.5 m X 2.2 m) Also a module of this size can produce 230-250 Watt of Electricity. Each module consists of approx 60 cells each producing around 4W of electricity.

1 MW of Electricity production will need  a surface area of  5.5 acres ( =2.22 hectare or 0.022 sq km)

On this account the National Solar Mission of India will need a total Solar Panel area of Approx 121000 Acres or  2662 sq km  ( approx 50km X 53km ) for 22GW of Solar Power.

Average Life Span of these modules is 25 years

There are two major technologies here :

1.	Photovoltaic of PV in short. This is cheaper and most popular. 2.	Thin Film e.g. Cadmium Telluride ( Other thin film technologies are CIGS and Amorphous Silicon )

Major Chinese companies in Solar Power production are : 1.	Sun Tech ( Revenue USD3.2 B – Installed Capacity  Approx 600 MW/Qtr installed capacity )- Largest manufacturer of PV modules in the world. 2.	Trina Solar ( Approx 400 Mw/Qtr ) 3.	Yingli Green Energy

American Solar Companies include : 1.	First Solar -- USD 2.8B Revenue in 2011. 2300 MW installed capacity in 2011. 2.	Abound Solar – Annual 65 MW expanding to 840 MW 3.	SunPower Corporation

Major market for Solar PV modules are USA, Germany , Italy , France, Japan China and India

Major Steps in making Photovoltaic modules are :

1.	Ingots --Mono/ Multi crystalline types. Cylidrical in shape from which wafers are sliced. 2.	Wafers 3.	Cells – Typically 4W 4.	Modules – Typically 60 cells of 4W each = 240 W
