Basic Design

  • 156 mm square cells
  • 4x8 cell panels, total of 32 cells per panel
  • dimensions – 29”x56” for each panel
  • 112 designer watts
  • we have enough solar cells for 15 panels

look @ pg. 43 of hurley for an example layout of the panels. The example is 4x8 as well, though the cells are larger than in the example, about 6.14 in^2. These sound fairly large, about 2.5'x4.5'. If we are working on two at a time with a small team of people, we will need significant table space.
