pi4_EL Table Flasher for PV Modules

New possibilities of cost saving in manufacturing of PV panels by means of combined inspection processes and enhanced quality assurance
pi4_EL Table Flasher (PresseBox) (Berlin, ) In cooperation with h.a.l.m. elektronik, a flasher expert, pi4 has developed an innovative EL Table Flasher system for PV panel manufacturing. It is a compact in-line system that unites high-class flasher technology and fully automatic electroluminescence inspection. Modules enter with the sunny side down on conveyours with a typical belt level of 900 mm or higher, which ensures an easy integration into new or already existing production lines. Additional handling of panels is superfluous.

The flasher unit contains a precise Class-AAA UI-Curvetracer measuring system that has been developed by h.a.l.m. elektronik in Frankfurt, Germany. The flasher unit provides a highly stable irradiance output and extraordinary long flash-times from a single light sorce.

After the flashing process is finished, electroluminescence inspection of panels starts. It is carried out by means of special high-resolution cameras by pi4 and runs fully automatically. Our software algorithms provide reliable results at stable operation and are able to detect even microcracks in polycrystalline cells. pi4_EL Table Flasher offers the same high quality of EL inspection as all other EL testers by pi4.

pi4_EL Table Flasher systems are available in various versions - as fully automatic in-line systems that boast short cycle times and can be easily integrated into a production line, or as semi-automatic or manual variants to be used in the filed of R&D.

pi4 and h.a.l.m. elektronik will introduce the new systems from September 25th through 28th in hall 3, booths J59 and H20.
