Why Solar?

• Oil, coal and other fossil fuels are coming to
  end, very shortly
• Environmental Degradation
• Plenty of Solar both- silicon on earth and
  sunlight from the sky
• Solar is versatile
• Solar is independent
• Solar is eternal, renewable
• Solar is divine too

3
Solar PV is the Smart Technology Choice of 21st
Century

• Solar is Eternal
• Solar is Reliable

4
Kerosene is Dangerous to the people the Planet
Earth

• A student studying using smoky and hazardous
  kerosene wick lamp
• Hes one among the 2 billion people world over
  who have no access to electricity even at the
  dawn of 21st century!!

13
The VOLTAGE of a solar cell is 0.5Volts, no
matter what is its size!
14
The CURRENT of a solar cell is directly
proportional to its size.

• The current produced by a solar cell is directly
  proportional to the intensity shines on it

Manpower

• For a typical 3MW Line per annum 3 Shifts/Day
• Engineers 2
• Foremen (Diploma) 4
• Artisans(ITI) 25
• Semi/Un-Skilled 5
• The above manpower requirement varies from
  company to company depending on the kind of
  equipments used, whether manual or automated
