  1. Solar PV Module Manufacturing D.T.Barki Noble Energy Solar Technologies Ltd YES/NEST Ltd/Dec'04

  2. 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 YES/NEST Ltd/Dec'04

  3. Solar PV is the Smart Technology Choice of 21st Century • Solar is Eternal • Solar is Reliable YES/NEST Ltd/Dec'04

  4. Kerosene is Dangerous to the people & the Planet Earth A student studying using smoky and hazardous kerosene wick lamp He’s one among the 2 billion people world over who have no access to electricity even at the dawn of 21st century!! YES/NEST Ltd/Dec'04

  5. The Solar Modules:…..From What? YES/NEST Ltd/Dec'04

  6. Quartz to Module Silicon grains Ingots Wafers Solar Cells Solar Modules YES/NEST Ltd/Dec'04

  7. The Process of Module Line 1. Glass Preparation 2. Cell Testing 3. Cell Tabbing 4. Stringing &Circuit Formation 5. Module Lay Up Preparation 6. Module Lamination 7. Curing 8. Framing & Assembly 9. Performance Test YES/NEST Ltd/Dec'04

  8. Materials • Solar cells • Low-iron content, toughened glass • Ethylene Vinyl Acetate (EVA) • Tedlar back cover (PVF) • Tinned copper interconnects & bus bars • Anodized Aluminium frame • RTV silicone • Terminal Box YES/NEST Ltd/Dec'04

  9. Solar Cell:The Basic Building Block for Making Solar Module YES/NEST Ltd/Dec'04

  10. Solar Cell Tester YES/NEST Ltd/Dec'04

  11. Solar Cells for Tabbing and Stringing YES/NEST Ltd/Dec'04

  12. Tabbed Solar Cells & Stringing YES/NEST Ltd/Dec'04

  13. The VOLTAGE of a solar cell is 0.5Volts, no matter what is its size! YES/NEST Ltd/Dec'04

  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 YES/NEST Ltd/Dec'04
