Electroluminescence in multiple modules on tracker in the field: massive efficient polarization

Abstract

More efficient and cost effective procedure for large scale daylight EL dEL measurements in PV plants. Pillars of this strategy working during the day without disassembling the modules and without the use of power supplies. An InGaAs camera (model Hamamatsu C 12741 03 640 x 512 pixel) has been used to take the dEL images
