I have 6 solar panels that are only 2 years old and giving varied dc voltage output. I'm hoping its the bypass diodes. I cant see any other damage to the cells on the panels. (Note: these are rejected panels - no warranty)
There are (3) Junction Boxes. (Positive-out) (center-no lead) and (Negative-out). They are potted for IP67 waterproof and sealed to the panel back. I removed the potting in all 3 boxes to identify the diodes. A THY 2550 was in all 3. Each box is tied to 24 cells.
I can't find an exact match to that diode #.? I cant find the manufacturer for that diode logo.?
Can someone point me to a diode that would be comparable?
I'd really like to improve the Forward Voltage Drop quality of the diode if you have any suggestions?
Thanks in advance for any help!
