The production process comprises the following major steps

  • Soldering of about 8 to 12 cells to form a so-called string using a copper strip
  • Simultaneous cleaning of the glass panel and applying a transparent film to the cleaned panel
  • Applying 4 to 8 strings to the film-coated glass panel
  • Soldering the strings
  • Applying additional films
  • Laminating the resulting sandwiches at high temperatures and pressures Trimming protruding pieces of film
  • Mounting of the aluminum frame
  • Installing and electrically connecting the junction box
  • Performing safety checks (high voltage)
  • Functional testing and module characterization (solar simulator)
  • Packaging (incl. measurement log)
