How can there be current at the negative pole of the photovoltaic panel

Bypass diodes are connected in parallel across solar cells to provide an alternative current path when the voltage across a cell is negative due to shading or it becoming faultyBypass diodes are connected in parallel across solar cells to provide an alternative current path when the voltage across a cell is negative due to shading or it becoming faultyLet's say I have 10 combiner boxes that are connected to an inverter, and while the inverter is running I see 3 combiner boxes recording negative current while the 7 of them are recording positive current, and there is no ground fault on the inverter. Potential induced degradation (PID) is a phenomenon that arises over time (months or even years). It may be negligible in the plant's early stage. Even if we know that a solar power array has a voltage of 600 volts between the positive and negative poles, we don't know whether the positive and negative poles have, respectively, 300 and -300 volts, 600 and 0 volts, or 900 and 300 volts. Efficiency is the most common characterization of solar cells and this is often expressed with a voltage current curve.
