6 FAQs about [Analysis of the cause of leakage of wall-mounted solar panels]

What causes small leakage currents in photovoltaic (PV) modules?

ABSTRACT: Small leakage currents flow between the frame and the active cell matrix in photovoltaic (PV) modules under normal operation conditions due to the not negligible electric conductivity of the module build-ing materials.

What happens if a solar cell leaks a DC current?

Predominantly the DC part of the leak-age current can cause significant electrochemical corrosion of cell and frame metals, potential-induced degradation (PID) of the shunting type and PID of the solar cells’ sur-face passivation [1,2,3].

Is leakage current related to electrical layout of PV array?

The obtained results indicate that leakage current is not only related with electrical layout of the PV array but also the resistance of EVA and glass. Need Help?

What is a typical leakage current?

Typically, the leakage current for this mounting method differs between 75 and 120 Î¼A for non rain conditions and up to 200 Î¼A for rain events. Also it can be observed that the magnitude of the leakage current increases because of an increase of the air humidity which is followed by dew on the module.

How does superstrate technology affect leakage current?

Because of the superstrate technology no barrier layer is between the glass and the TCO layer. That leads to an extreme boost of the leakage current of this module. The maximum value reaches 340 Î¼A. In comparison to the unbroken modules the maximum value reaches 12 Î¼A. This is similar to the negative potentials.
