The system voltage of solar panels drives a leakage current between the solar cells and the grounded metal frames. This results in many different forms of potential induced degradation, including shunting, polarization,1 delamination, and corrosion. This leakage current can be composed of either. . In three-phase transformerless inverters, for systemic reasons, the oscillations are of a much smaller amplitude and, as a result, they generate smaller leakage currents. This fluctuating voltage constantly changes the state of. . The issue of leakage in photovoltaic energy systems is controversial and you will find a large number of professional opinions on the subject.
