PID-Resistance IntroductionThe first company with all products meet PID-resistance
What Is PID?
1
the cells’ voltage
(which module closest
to the negative pole
is several hundreds of
volts .-400 -200 0 200 400

REFERENCE: S. Pingel, O. Frank, “POTENTIAL INDUCED DEGRADATION OF SOLAR CELLS AND PANELS”, 2010
Pease be noticed that we don’t do pre-degradation before testing PID, so this result probably be influenced by LID, and the real PID values should be less than those values.
