I have had a new tracker (from Solaflect) installed and it's working fine as a system, but I am puzzled by a discoloration of some cells in the Sunpreme GxB 320T (bifacial) modules that seems to be very apparent during overcast and/or wet conditions. I originally thought it might be moisture incursion in the modules, then I speculated it was evaporation of dew or condensation on the glass due to temperature variations in the cells, but I have since figured out that the discoloration is entirely within the glass sandwich. I've been googling around but I haven't run across anything else that looks quite like it.
Does anyone have experience with this or ideas? Should I be worried?
