Solarzentrum Stuttgart Poster "DaySy Daylight EL & PL: Estimates PID Losses in the Field" wins Award at NREL PV Module Reliability Conference, Golden, Colorado. Authored by Liviu Stoicescu and Michael Reuter, the poster shows how to extract the Rp and relative cell efficiency from DaySy EL and PL measurements. Thus allowing to estimate the PID losses in the field! Further, DaySy PL allows for detection of PID already in early stages.
