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. . This leakage current is a reactive current with its phase rotated by 90° to the line voltage. In the first approximation, it is without loss. 3 How Does the Leakage Current Affect the Detection of the Residual Current? The capacitive leakage current described in Section 2 is a reactive current. . The issue of leakage in photovoltaic energy systems is controversial and you will find a large number of professional opinions on the subject. Some recommend completely ignoring the matter, while others do recommend monitoring the phenomenon and executing a systemic solution once every few years. . = 937.
