  • Measurement of a solar cell
  • The right busbar is not connected to the cross connector

  • Measurement of a solar cell with microcrack
  • The crack is clearly visible
  • No soldering points are visible below the crack
  • The crack has cut through the busbar

  • Measurement of a cell in a module
  • In the by-component of the magnetic field the soldering points become visible
  • Some soldering points are missing
  • It can also be determined whether the solder pads are located in the middle of the pad or offset.
