6 FAQs about [Causes of water leakage in photovoltaic panels in industrial areas]

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.

How to eliminate leakage current in solar PV array system?

There are two distinct methods to eliminate the leakage current in the solar PV array system: (i) obstruct the leakage current, (ii) reduce the variation/constant common-mode voltage. The additional diodes/switches are incorporated in the system to obstruct the leakage current by disconnecting the PV array from the grid side network.

How do leakage currents affect PV module efficiency?

This will induce leakage currents flowing through the module package potentially leading to significant PV module efficiency loss. In standard p-type c-Si PV modules, leakage currents can flow from the module frame to the solar cells along several different pathways (Fig. 2), which are depicted as follows:12,13,44,48–50

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].

How does temperature affect leakage current?

This decreases the humidity in the microclimate of the module. 51 The temperature usually increases the leakage current, but in this case, it will lead to a smaller total leakage current because the surface conductivity is reduced—the current paths become concentrated at the module edges. 51,115

Why is leakage current not a universal indicator of PID?

Leakage current of modules under system voltage is not a universal indicator of PID because power recovery is seen in some cell technologies, some current paths are more deleterious than others, and solutions to prevent PID include lowering resistance of the current pathway (i.e. making SiNx AR coating more conductive, discussed in Section 6.1.1).
