POLYCRYSTALLINE SOLAR PANELS

• Energy of the Future

PANEL PRODUCTION PROCESS

• Raw silicone formed into a block or ingot
• This block is then sliced into thin cells
• Each of these cells is printed on one side with a
  positive material and on the other side with a
  negative material
• Cells connected in series to create a panel
• Panels have the appearance of shattered glass
• Ex 12 V panel _at_ 18 V 36 cells connected in
  series with each cell producing 0.5 V

EFFICIENCY

• Cheaper per watt than mono-crystalline panels but
  less efficient
• Double the efficiency of amorphous panels but
  more expensive
• Polycrystalline 13-15 efficient
• 3-5 years in energy payback (Study done by
  National Renewable Energy Lab in Golden, CO.)
• Efficiency amount of power produced / size of
  panel
