New deterioration diagnosis tech for individual modules in PV panel strings

Conceived by scientists in Japan, the system consists of a a xenon flash lighting system and a detector capacitor. It can reportedly examine solar modules and find the degraded ones without disconnecting the string's electrical wiring. Researchers from Japan's Ibaraki University and the University of Shiga Prefecture have developed a novel deterioration diagnosis device for PV modules that can reportedly inspect a string of cells and spot the deterioration in each individual module without disconnecting the string's electrical wiring. "Detection of deterioration of individual PV modules can ...
