  • Broken cross and cell connectors can be reliably found in the module during operation.
  • Example: measurements 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
  • Above the crack no soldering points are visible
  • The crack has cut through the busbar

  • Measurement of a cell
  • The solder points are visible in the data
  • Some solder joints are missing
  • With the help of the measurement it can be determined whether the solder point is in the middle of the solder pad.

  • Example: Comparison between a normal and an abnormal junction (short-circuited bypass diode)
  • The short circuit changes the current flow in the junction box and thus also the magnetic field.
  • Analysis of closed juction boxes during the operation of PV systems is possible.
